1. When you need to select multiple layers, you can first use the selection tool to select an area in the file, and a selection virtual box will appear on the screen; then press and hold the "Alt" key on the keyboard, when the cursor changes to a band in the lower right corner When a small "-" sign is followed by a large "+" sign, this means reducing the selected area or pixel, and pulling out a second box inside the first box; then hold down the "Shift" key, and when the cursor changes to a When there is a big "+" sign with a small "+" in the lower right corner, pull out the third selection box inside the second box, so that they can be used in turn to make multi-layer selections.
2. In Photoshop 5.0 or above, we right-click the text in the editing area, select the "Layer" command in the pop-up menu, and select "Effects..." from the subsequent lower-level menu. command, you can quickly create shadow and light effects that change with the font.
3. When using the Layer-Free Transform function, hold down the Ctrl key on the keyboard and drag a control point to deform and adjust it at will; hold down the Shift+Ctrl compound key on the keyboard at the same time and drag a control point for tilt adjustment; hold down the Alt key on the keyboard and drag a control point for symmetrical adjustment; hold down the Shift+Ctrl+Alt keys on the keyboard at the same time and drag a control point Perspective effect can be adjusted.
4. When moving layers and selection boxes, if you hold down the Shift key on the keyboard at the same time, you can move horizontally, vertically, or at a 45-degree angle, and hold down the direction keys on the keyboard to move 1 pixel at a time. Hold down the Shift key and simultaneously hold down the arrow keys on the keyboard to move 10 pixels at a time.
5. Sometimes in order to free up more operating space in the image editing area, we need to quickly hide the toolbar and multiple floating panels. When hiding, we need to use the mouse to click the close button on the operation panel one by one. Next time you want to open the control panel, you have to use the mouse to open it one by one, which is very inconvenient every time. In fact, we can hold down the "Shift" and "Tab" keys on the keyboard at the same time, so that the floating panel will be hidden immediately and disappear from the screen. If we press the two keys at the same time, the panel will appear again; if we only press "Tab" key, the toolbar and the floating panel will be hidden together. Press the key again and they will appear at the same time.
6. When using the pen tool to create a path, hold down the Shift key to force the path or direction line to be horizontal or vertical at a 45-degree angle. Hold down the Ctrl key to temporarily switch to the path selection tool, and hold down the Alt key to move the pen cursor. Click on the black node to change the direction of the direction line so that the curve can turn; hold down the Alt key and use the path selection tool to click on the path to select the entire path; to select multiple paths at the same time, hold down the Shift key on the keyboard and select them one by one. Click; when using the path selection tool, hold down the Ctrl + Shift compound keys on the keyboard and move closer to the path to switch to the add node and subtract node pen tools.
7. When using Photoshop, many users like to set up the working environment of Photoshop by themselves; but in some cases, we need to restore the default environment settings of Photoshop. So how do we operate you? The environment parameter settings of Photoshop5.5 are saved in an "Adobe Photoshop 5.5 Prefs.psp" file. To restore Photoshop's default settings, simply delete the file. The next time you start Photoshop, it will set the system environment with default parameters and restore it to the state when it was first started after installation. When exiting Photoshop, it will also create a new "Adobe Photoshop 5.5 Prefs.psp" file to save the current settings. The "Adobe Photoshop 5.5 Prefs.psp" file is saved in the Adobe\Photoshop 5.5\Adobe Photoshop 5.5 Settings directory. The environment parameter setting file of Photoshop5.0 is "Adobe Photoshop 5 Prefs.psp", and the path is "Adobe\Photoshop 5.5\Adobe Photoshop 5.0 Settings\".
8. When we use various tools in the toolbox, we often set the parameters on the tool options panel according to actual needs. When we need to restore the default settings of the tool options panel, we can click the black triangle button in the upper right corner of the tool options panel to open a panel menu. Select the "Reset Tool" option to restore the option panel settings of the current tool; or select the "Reset All Tools" option to restore the option panel settings of all tools.
9. When we are using the brush tool and want to adjust the opacity, according to the conventional operation method, we need to use the mouse to open the transparency setting dialog box in sequence. There are many steps and the operation is very troublesome. Now we can directly press the numeric keys on the keyboard to set the transparency parameters. For example, when we press the "0" key on the keyboard, it means setting the transparency value to 100%, that is, setting it to be completely transparent; pressing the "1" key means setting the transparency value to 10%. If you press "4" first Press "5" again, then the transparency will be 45%, and so on.
10. If you want to use an image edited with Photoshop on a Web page, you can set the mode of the image to Indexed Color, because this mode has the advantages of small file size and easy transmission; if you continue to edit the image By converting the image to gif98a export (gif output), you can set the image to a transparent effect and save the file in gif format. The image in this format has the advantages of high compression rate, interactive display, etc., and is currently a popular Web Image format.
11. When installing Photoshop, we select the "All other countries" command in "Select Country"; select Custom in "Setup Type"; make sure Cmap files are selected in "Selcet Components"; install the program in this way After completion, our Photoshop can use Chinese normally.
12. When we edit a picture file, sometimes we need to remove the color of the picture outside the selected object. In this case, we can press the "Delete" key on the keyboard, and the outside of the selection area will become the background color or transparent, depending on What is the background content we set.
13. When we want to copy the selected objects in the file, we must use the copy command in the edit menu. If we only copy once, we may not notice the trouble, but if we want to copy multiple times, we need to click multiple times at a time, which adds up to quite inconvenient. So is there a simpler operation method? The answer is of course yes. Here we provide a quick operation method. The specific steps are as follows: First, we can use the selection tool to select the object to be operated, then click the move tool with the mouse, and then hold down the keyboard. Hold the "Alt" key on the mouse. When the cursor turns into two overlapping arrows, one black and one white, just drag the mouse to the desired position. If we want to perform multiple copy operations, we can repeatedly release Just put the mouse.
14. In Photoshop, there are many times when you need to modify the values of settings. Generally, there will be a black triangle on the right side of the value box. Click it and a sliding ruler will appear. You can modify the value by dragging the ruler, but sometimes it is not very accurate. At this time, you can press the down arrow key on the keyboard (each press means the value increases by one) and the up arrow key (each press means the value decreases by one) to accurately adjust the value. If you hold down the "Shift" key, each time you press it, the value will increase or decrease by 10.
15. If we want to add a new command after a command in a macro (Action), we can first select the command, then click the Begin recording icon on the palette, and select the command, and then click the Stop recording icon.
16. If we want to drag and drop a copy between two operation windows, hold down the Shift key on the keyboard during the dragging process, and the image will be automatically centered when it is dragged into the target window.
17. Hold down the Shift key, and then drag a new selection area in the image. We will see that the new selection area and the previous selection area are merged to form a larger selection area; When you hold down the Alt key to select an area, you can subtract the newly selected area from the previous selection area; when you hold down the Shift key and the Alt key to select an area, you can get the portion that intersects with the previously selected area.
18. In Photoshop 5.0 or above, we use the mouse to click the small triangle in the upper right corner of the History control panel and select the "Clear history" command from the pop-up menu, which can temporarily alleviate our problem with virtual memory. need.
19. Due to printing reasons, the pictures we scan into the computer will have some moire. If we edit them on this basis, it will affect the future effects. At this time, we can first use "Despeckle" in the "Noise" filter for processing, then the picture will become slightly blurred; then use "Sharpen Edge" in the "Sharpen" filter (what should be paid attention to here is setting the value Smaller) and then process it, and you're done. At this time, even if you use a magnifying tool to observe, there will be no moire.
20. After we have used Photoshop for a period of time, a large number of pictures and image files have been stored in the folder. When we need to call a file that we have not used for a long time and forget its file name, we need to open the files in the folder one by one to search one by one. This is obviously too troublesome. Here we have a relatively quick operation method. The specific operation steps are as follows: First, click the File menu item in the Photoshop menu bar with the mouse, and select the Automate menu item from the pop-up drop-down menu, and then select the Automate menu item from the lower-level menu behind it. Select the Contact Sheet command, which can create a small thumbnail for each file in the entire folder and store it in an image file. This facilitates future retrieval and review, and saves us valuable time.
75 Tips for Photoshop
The reason why Photoshop has powerful functions while still maintaining good usability should be largely attributed to its neat and concise interface and easy-to-use customizability (in addition to its large number of tools and commands) .
In fact, there are a lot of amazing "hidden" functions in Photoshop. No matter how many years you have used Photoshop, you will continue to discover more and more things. I doubt anyone claims to know "everything" about Photoshop (except maybe ADOBE's software engineers).
The 75 tips below will help you (whether you're a newbie or a seasoned pro) master some of Photoshop's "hidden" features to help complete complex tasks faster and more efficiently; or they will Tell you some capabilities of PHTOSHOP that you never knew before! For your convenience, we have divided them into eight parts:
*
Interface skills[↑]
1). You may know that pressing the Tab key can hide the toolbox and floating panels, and pressing the Shift+Tab key can also hide only the floating panels (while leaving the toolbar visible).
2). Hold down the Shift key and click the title bar (the top blue bar) of the floating panel to make it snap to the nearest edge of the screen.
3). Double-click each column on the floating panel (the one with the title) to minimize it. The Minimize button on the floating panel can be used to switch between compact mode (only minimal options and content are visible) and normal mode (all options and content on the panel are displayed).
4). You can open the options panel of the current tool by pressing the Enter key (or double-clicking the tool button on the toolbox). Otherwise, it can only be opened through the Window/Show Options command on the menu.
5). Use the scaling area (in the lower left corner of the Photoshop form or navigator panel) to quickly select an accurate display ratio. Press Shift+Enter after entering a value to keep the cursor in the scaling area. .
6). To change the display information of the status area (at the bottom of the window, the file size is displayed by default, which can be opened through Window/Show Status Bar), press the button on the status area to select a new item from the pop-up menu. Click the left area of the button in the status area to display the printing size of the current file, hold down Alt and click to display the file size and resolution, hold down Ctrl and click to display collage information.
7).Tired of gray canvas background? Select the Paint Bucket tool [K] (Paint Bucket), hold down Shift and click on the edge of the canvas to set the background color of the canvas to the current foreground color. (Note: To revert to the default colors, set the foreground color to 25% gray (R192, G192, B192) and Shift-click the edge of the canvas again.)
8). The Cancel button in all dialog boxes in Photoshop can be turned into a Reset button by holding down the Alt key. This allows you to easily return to the initial values without having to cancel and start over.
9). The CapsLock key on the keyboard can control the cursor to switch between precise state and standard state. Note: If the cursor has been set to the precise state in Photoshop's parameters [Ctrl+K, Ctrl+3] (File/Preferences/Display & Cursors...), the CapsLock key will not work.
10). Press the "F" key to switch between Photoshop's three different screen display modes (standard display mode → full screen display mode with menu → full screen display mode) (or you can use the button at the bottom of the toolbox). Tip: Press Shift+F in full-screen mode to toggle whether to display the menu. Double-click the blank space in the background of Photoshop to open the file command [Ctrl+O] (File/Open).
11). Hold down Shift and click the color bar under the color panel to change the type of color spectrum displayed. Alternatively, you can right-click the color bar and select other color modes from the pop-up color bar option menu.
12). Right-click the title bar of the picture window to quickly call some commands, such as canvas size command, image size command, copy, etc. Click any blank (gray) area on the palette panel to add a custom color to the palette, hold down the Ctrl key and click to subtract a color, hold down the Shift key and click to replace a color.
13). Color data can be exchanged between Photoshop and other programs (other programs that support hexadecimal color values) by copying and pasting the hexadecimal color values displayed in the Photoshop color picker.
*Tool skills[↑]
14). To use the brush tool to draw a straight line, first click on the image, then move the mouse to another point and hold down Shift and click on the image again. Photoshop will use the current drawing tool to draw a straight line between the two points.
15). Hold down the Ctrl key at any time to switch to the move tool [V]. Hold down the Ctrl+Alt key and drag the mouse to copy the current layer or selection content.
16). Press and hold the space bar to switch to the Hand Tool [H] (Hand Tool) at any time.
17). The shortcut key for the zoom tool is “Z”. In addition, Ctrl + Spacebar is the zoom tool, and Alt + Spacebar is the zoom out tool.
18). Press Ctrl+"+" key and "-" key to enlarge and reduce the view of the image respectively; correspondingly, press the above hotkey while holding down the Alt key to automatically adjust the window to full screen display (Ctrl+Alt+ " +" and Ctrl+Alt+ "-" ), this is very useful! (Note: If you want to automatically resize the window according to the size of the picture when using the Zoom tool, you can check the "Resize Windows to Fit" option in the options of the Zoom tool.)
19). When selecting a color with the eyedropper tool, hold down the Alt key to define the current background color.
20). Combined with the color sampler tool [Shift+I] (Color Sampler Tool) and the information panel (Window/Show Info), we can monitor the color changes of the current picture. The color values before and after the change are displayed next to their sampling point numbers on the information panel. The color mode of the sampling point can be defined through the pop-up menu on the information panel. To add a new sampling point, just click anywhere on the canvas (using the color sampler tool). Hold down the Alt key and click to remove the sampling point. Note: Only four color sampling points can be placed on a picture at most. Tip: When a dialog box pops up in Photoshop (for example: color level command, curve command, etc.), you must hold down the Shift key to add a new sampling point. Click and Alt+Shift-click a sample point to subtract it.
21). The Measure Tool is very convenient for measuring distances (especially on diagonal lines), and you can also use it to measure angles (just like a protractor). First, make sure the information panel [F8] (Window/Show Info) is visible. Select the measure tool, click and drag out a straight line, hold down the Alt key and drag out a second straight line from the node of the first line, so that the angle between the two lines and the length of the line are displayed in
*Command skills[↑]
22). To use the filter just used again, select Filter/Last Filter [Ctrl+F] from the menu; to use the filter just used with new options, remember to add an extra Alt key (Ctrl+ Alt+F or Alt + Filter/Last Filter ). Tip: To undo the last filter or adjustment effect (or change the composition mode), press Ctrl+Shift+F (Filter ? Fade Filter).
23). If you have recently copied an image and stored it in the clipboard, Photoshop will use the size of the image in the clipboard as the size of the new image when creating a new file [Ctrl+N] (File/New...) Default size. To bypass this feature and use the last settings, hold down the Alt key [Ctrl+Alt+N] ( Alt + File ?New... ) while opening.
24). Press Ctrl+Alt+Z and Ctrl+Shift+Z to move backward and forward in history respectively (or you can use the menu in the history panel to use these commands). Use these hotkeys in conjunction with the Undo [Ctrl+Z] (Edit/Undo) command to freely switch between history and current status.
25).Alt+Backspace and Ctrl+Backspace key combinations are used to fill the foreground color and background color respectively. Another very useful hotkey is Shift+Backspace––open the fill dialog box. Tip: Press the Alt+Shift+Backspace and Ctrl+Shift+Backspace key combinations to only fill existing pixels (keep transparent areas) when filling the foreground and background colors.
26). When using the Free Transform tool [Ctrl+T] (Edit/Free TransFORM), hold down the Alt key (Ctrl+Alt+T or Alt + Edit/Free TransFORM) to copy the original layer (in current selection) and then transform it on the copied layer. Tip: Ctrl+Shift+T (Edit/TransFORM? Again) is to perform the last transformation again, Ctrl+Alt+Shift+T (Alt + Edit/TransFORM/Again) is to copy the original image and then perform the transformation.
27). To prevent the marquee from adsorbing on the picture border when using the Crop Tool [C] (Crop Tool), hold down the Ctrl key while dragging the control point on the Crop Tool marquee.
28). To correct a tilted image, first use the measuring tool to draw a line on the image where it can be used as a horizontal or vertical reference (such as the image border, door frame, horizontal line between the eyes, etc.), and then draw a line from Select Image/Rotate Canvas/Arbitrary from the menu. After opening, you will find that the correct rotation angle has been filled in automatically. Just click OK. Note: You can also use the crop tool to complete the rotation and shearing work in one step: use the crop tool first
[C]Draw a box, drag the control points on the selection box to adjust the angle and size of the selection box, and finally press Enter to rotate and shear. Tip: The angle measured by the measurement tool will also be automatically filled in the numeric transformation tool (Edit/TransFORM/Numeric) dialog box.
29). Use the "New layer by copy [Ctrl+J] (Layer/New/Layer Via Copy)" or "Create new layer by cut [Ctrl+J] (Layer/New/Layer Via Cut)" command Copy & Paste and Cut & Paste can be done in one step. NOTE: Pastes via the Copy (Cut) New Layer command are still placed in their original location, whereas via Copy (Cut) & Paste they are pasted to the center of the image (or selection).
30). After cropping the image (using the cropping tool or selecting Edit/Crop), all pixels outside the cropping range will be lost. If you want to crop without loss, you can use the "Canvas Size (Image/Canvas Size)" command instead. Although Photoshop will warn you that some clipping will be made, for some reason it doesn't - all the "clipped" data is kept outside the frame. Tip: ImageReady's crop command (Image/Crop) will ask whether you want to delete the cropped area or hide it. Note: This does not work in indexed color mode (using the canvas size command in indexed mode will lose pixels outside the frame).
31). When merging visible layers, hold down the Alt key [Ctrl+Alt+Shift+E] (Alt + Layer/Merge Visible) to copy all visible layers and merge them into the current layer. Tip: You can also hold down the Alt key when merging layers (Layer/Merge Down), which will copy the current layer and merge it into the previous layer. There is no corresponding hotkey for this command – Ctrl+Alt+E does not work.
*Selection skills: [↑]
32). When using the Marquee Tool [M] (Marquee Tools), hold down the Shift key to draw a square or circle selection; hold down the Alt key to draw a selection centered on the starting point.
33). Use the "Reselect" command [Ctrl+Shift+D] (Select/Reselect) to load/restore the previous selection.
34). When using the Lasso tool to draw a selection, press the Alt key to switch between the Lasso tool and the Polygonal Lasso tool.
35). When drawing a selection, hold down the space bar to move the selection being drawn.
36). As we all know, holding down the Shift or Alt key can increase or trim the current selection, but did you know that pressing the Shift and Alt keys at the same time to outline can select the intersecting parts of the two selections? Tip: Hold down the Ctrl key and click on the layer's icon (on the Layers panel) to load its transparency channel. Then hold down the Ctrl+Alt+Shift key and click on another layer to select the area where the transparency channels of the two layers intersect.
37). Switch to quick mask mode [Q] before zooming or copying the image to retain the original selection.
38). Tips on using layers[↑]
39). Press Shift+"+" key (forward) and Shift+"-" key (backward) to switch between the composition modes of various layers. We can also press Alt+Shift+"a certain character" to quickly switch to the synthesis mode. N = Normal
I = Dissolve
M = Multiply
S = Screen
O = Overlay
F = Soft Light
H = Hard Light
D = Color Dodge
B = Color Burn
K = Darken
G = Lighten
E = Difference (Difference)
X = Exclusion
U = Hue
T = Saturation (Saturation)
C = Color
Y = Luminosity
Q = Behind (Behind 1)
L = Threshold (Threshold 2)
R = Clear ( Clear 3 )
W = Shadows 4
V = Midtones 4
Z = Highlights (Highlights 4)
Numbered ones are valid for the following situations: [Note 1]
Only works in layers with "Preserve Transparent Areas" turned off
Indexed Mode
Use straight line [N] (Line) and paint bucket [K] tool (Bucket Tools) on multi-layer pictures
Dodge and Burn Tools[O](Dodge and Burn Tools)
40). Press the number keys directly to change the opacity of the current tool or layer. Press "1" for 10% opacity, "5" for 50%, and so on, and "0" for 100% opacity. Continuously pressing a number key such as "85" means the opacity is 85%. Note: The above hotkeys are also valid for the current drawing tool, so if you want to change the opacity of the current layer, first go to the move tool or a selection tool.
41). Hold down Alt and click the eye icon in front of the desired layer to hide/show all other layers.
42). Hold down Alt and click the brush icon in front of the current layer to unlink it from all other layers.
43). To clear all layer effects on a certain layer, hold down the Alt key and double-click the layer effect icon on the layer; or select Layer/Effects/Clear Effects in the menu. Tip: To turn off one of the effects, hold down the Alt key and select its name in the Layer/Effects submenu. Or you can uncheck its "Apply" mark in the Layer Effects dialog box.
44). Hold down the Alt key and click between two layers in the layer panel to group them together. This function is very useful when some layers are linked together and you only want to group some of them (because the group command [Ctrl+G] (Layer/Group with Previous) will change the current layer when it is linked to other layers. For the group link layer command [Ctrl+G] (Layer/Group Linked)).
45). Here is a time-saving way to add an adjustment layer (Layer/New/Adjustment Layer): just hold down Ctrl (it should be the Alt key on PC, film note) and click "Create New Layer" icon (at the bottom of the Layers panel) to select the type of adjustment layer you want to add!
46). Press the Alt key and click the Delete button (at the bottom of the layer panel) to quickly delete a layer (without confirmation). This also applies to channels and paths. In addition to editing the layer mask in the channel panel, press Alt and click the mask icon on the layer panel to open it; hold down the Shift key and click the mask icon to close/open the mask (a red cross X will be displayed to indicate that the mask is closed ). Alt+Shift-click the layer mask to display it in ruby color (50% red). Hold down the Ctrl key and click on the mask icon to load its transparent selection.
47). Click the "Add Layer Mask" icon on the layer panel (at the bottom of the layer panel) to add a mask that displays all the contents of the current selection by default (Layer/Add Layer Mask/Reveal All); press Hold the Alt key and click the "Add Layer Mask" icon to add a mask that hides the current selection content (Layer/Add Layer Mask/Hide All).
48). Click the blank area on the path panel to turn off the display of all paths. Tip: Press Ctrl+Shift+H to switch whether the path is displayed (View ? Show/Hide Path).
49). When clicking several buttons below the path panel (fill path with foreground color, stroke path with foreground color, load path as selection), hold down the Alt key to see a series of available tools and/or or options. When the current tool is the Move tool (or hold down the Ctrl key at any time), right-click on the canvas to open a list of all layers at the current point (sorted from top to bottom): Select the name of a layer from the list to make it the current layer. Tip: Hold down the Alt key and right-click the mouse to automatically select the uppermost layer of the current point, or open
50). The Auto-Select Layer option in the Move Tool Options Panel is also available. Tip: Hold down the Shift key (Alt+Shift+right-click) to switch whether the current layer is linked to the top layer.
51). Skills of auxiliary lines and rulers[↑]
52). Hold down the Alt key while dragging the auxiliary line to switch between horizontal auxiliary lines and vertical auxiliary lines. Hold down the Alt key and click on an existing vertical guide line to convert it to a horizontal guide line, and vice versa.
53). Note: Auxiliary lines are created by dragging them out of the ruler, so make sure the ruler is turned on [Ctrl+R] (View/Show Rulers).
54). Holding down the Shift key while dragging the guide line will force it to snap to the scale on the ruler.
55). Double-click the auxiliary line to open the auxiliary line & style parameter setting dialog box [Ctrl+K, Ctrl+6] (File/Preferences/Guides & Grid).
56). Double-click the ruler [Ctrl+R] to open the unit & ruler parameter setting dialog box [Ctrl+K, Ctrl +5] (File/Preferences/Units & Rulers). Tip: You can also select the standard measurement unit in the Options menu on the information panel.
57). The coordinate origin of the ruler can be set anywhere on the canvas. Just drag from the upper left corner of the ruler to apply the new coordinate origin; double-click the upper left corner to restore the coordinate origin to the default point.
58). It is also a good idea to use the path tool to create auxiliary lines of curves and diagonals. Simply trace a path with the Pen Tool and it will serve as a guide when drawing or coloring (the path will always remain visible). Tip: Use the hide path command [Ctrl+Shift+H] (View ? Hide Path) to switch the path display or not.
59). The auxiliary lines will not only snap to the edges (top, bottom, left, and right) of the current layer or selection, but will also be aligned with the horizontal or vertical center (of the current layer or selection). The reverse is also true: selections and layers will also snap to existing auxiliary lines (edges and centers). Note: The guide lines will not snap to the background layer. And to achieve the above function, you must first turn on the "Snap To Guides" [Ctrl+Shift+ ] (View/Snap To Guides) option. Tip: To find the center of the screen, create a new layer [Ctrl+Shift+N] (Layer/New Layer) and fill [Shift+Backspace] (Edit/Fill) a layer and then snap the auxiliary lines to the vertical center and horizontal center.
60).Navigator and action skills[Note 1][↑]
Many times it is faster to use the keyboard to control the navigator (navigation) than the mouse. Here is a list of some commonly used Navigator hotkeys:
Home = Go to the upper left corner of the canvas
End = to the lower right corner of the canvas
PageUp = Scroll the canvas up one page
PageDown = Scroll the canvas down one page
Ctrl+PageUp = Scroll the canvas one page to the left
Ctrl+PageDown = Scroll the canvas one page to the right
Shift+PageUp = scroll the canvas up 10 pixels
Shift+PageDown = Scroll the canvas down 10 pixels
Ctrl+Shift+PageUp = Scroll the canvas 10 pixels to the left
Ctrl+Shift+PageDown = Scroll the canvas 10 pixels to the right
61). Use Ctrl+Tab/Ctrl+F6 to switch between multiple documents (or you can also use the Window menu), which is very convenient!
62). Use the restore command [F12] (File/Revert) to restore the current document to the state when it was last saved. warn! In Photoshop5.0, the restore command will clear the history at the same time! This means that all changes since the last save using the restore command will be lost! Photoshop5.5 corrects this.
63).CHANNEL also has its corresponding default hotkey. This makes adding, subtracting and intersecting operations between selections/masks saved as channels very fast and easy. Here are some common patterns:
RGB color CMYK color Index color
Ctrl+“~”= RGB
Ctrl+1 = red
Ctrl+2 = green
Ctrl+3 = Blue
Ctrl+4 = Other channels
Ctrl+9 =Other channels
Ctrl+“~” = CMYK
Ctrl+1 = cyan
Ctrl+2 = Magenta
Ctrl+3 = Yellow
Ctrl+4 = Black
Ctrl+5 = Other channels
Ctrl+9 =Other channels
Ctrl+1 = Index
Ctrl+2 = Other channels
Ctrl+9 =Other channels
For example: To create a selection to represent the intersection of channel 7 and channel 9, press Ctrl+Alt+7 (to load channel 7 as a selection) and then press by Ctrl+Alt+Shift+9 (and then combine it with channel 9 intersect).
64). Hold down the Ctrl key and drag and drop in the agent preview area of the navigator to update the visible area of the current document. Tip: Hold down the Shift key while dragging the display box in the agent preview area to lock the movement direction to horizontal or vertical. Tip: The color of the display box in the agent preview area can be changed in the panel options of the Navigator panel.
65). If you only want to execute a single step in the Action, select the step you want to execute and then hold down the Ctrl key and click the Play button (at the bottom of the Behavior Panel). Note: If you want to change the parameters of some commands in an action, double-click the corresponding step to open the relevant dialog box: any newly filled values will be automatically stored.
66). To start execution at a specific step in an action, just select the starting step and press the Play button (at the bottom of the Behavior panel).
67).Copying techniques[↑]
68). You can use the Marquee Tool [M] (Marquee Tool) or the Lasso Tool [L] (Polygonal Lasso) to drag the selection from one document to another. When dragging a selection or layer from one document to another, hold down the Shift key to center it on the destination document. Tip: If the source and destination documents are the same size (dimensions), the dragged element will be placed at the same location as the source document (rather than in the center of the canvas). Note: If the destination document contains a selection, the dragged element will be placed in the center of the selection.
69). When you want to move multiple layers between different documents, first link them, and then you can use the move tool to drag multiple layers between documents at the same time. Note: You cannot drag multiple layers simultaneously in the Layers panel to another document (even if they are linked) – this will only move the selected layers.
70). To arrange multiple layers into a group, the fastest way is to link them first, and then select the group link layer command [Ctrl+G] (Layer/Group Linked). You can then cancel the link if you wish.
Note: This technique can also be used to merge [Ctrl+E] (Layer/Merge Down) multiple visible layers (because when the current layer is linked to other layers, the "Group with previous" command ” will become the “Group Linked” command).
71). There is a smart way to rearrange multiple layers at the same time (in the Layers panel): first link the desired layer to Group [Ctrl+G] (Layer/Group with Previous), in the Layers panel Drag it to a new location and ungroup it.
72). To create a copy document for the current historical state or snapshot (Window/Show History):
a) Click the "Create a new document from the current state (New Document)" button
b ) Select New Document from the History panel menu
c ) Drag the current state (or snapshot) to the "Create new file from current state" button
d ) Right-click on the desired state (or snapshot) and select New Document from the pop-up menu
73). Drag a certain historical state of the current picture in the historical state to the window of another picture to change the content of the target picture.
74). Hold down the Alt key and click on any historical state (except the current and most recent state) to copy it. The copied state then becomes the current (most recent) state.
75). Hold down Alt and drag the step in the action to copy it to another action.
PS channel mixer
In versions after Photoshop 5.0, the "Image"--"Adjust" function There is a "Channel Mixer" tool under the table. Most people may rarely use it, and various professional media articles rarely introduce this tool in detail. In fact, this is a very useful tool, which can greatly correct the image when certain channels lack color information. The Channel Mixer tool allows you to use the color information of one color channel to affect the color of other color channels, which is not possible with other adjustment tools. Using this command, you can complete the following operations:
1. Effectively correct the color cast phenomenon.
2.Choose different percentages from each color channel to create high-quality grayscale images.
3. Create high-quality toned color images.
The following is a detailed introduction to the channel mixer and the above points.
1. Working principle of channel mixer
The working principle of the channel mixer is: select a certain channel in the image as the processing object (ie, the output channel), and then perform addition and subtraction calculations based on the information of this channel and other channel information of the image to achieve the purpose of adjusting the image. Note that the color information being added or subtracted comes from the same image position in this channel or other channels. That is, the image color information of a certain channel in space can be calculated from the color information of this channel and other channels. The output channel can be any channel of the source image. The source channel will be different according to the color mode of the image. When the color mode is RGB, the source channels are R, G, and B. When the color mode is CMYK, the source channels are C, M, Y, K. Assume that the cyan channel is used as the processing object, that is, the result of the operation in the picture is only reflected in the cyan channel, so the cyan channel is the output channel. The calculation in the figure is: the original color information of the cyan channel of all images (the slider is still at 100%), minus 32% of the yellow information of the same image position, plus 22% of the magenta channel color information of the same image position. %, and then increase the dot size by 16% on this basis. Therefore, the output image with cyan dot percentage is: C=C+Mx22%-Yx32%+16%. For example, the color of an image is C40%M50%Y30%K0%. After the * operation in the picture, the output color is C57%M50%Y30%K0%. The "constant" in the figure means: the information of this channel directly increases or decreases the percentage of the maximum value of the color representation. Here 10% is actually 10% × 100%.
The channel mixer only works when the image color mode is RGB or CMYK. It cannot operate when the image color mode is LAB or other modes.
2. Operation of channel mixer
1. Open "Image" - "Adjustment" - "Channel Mixer".
2. Select the output channel, which is the channel you want to adjust.
3. Drag the slider of any source channel to the left to reduce the percentage of the output channel that channel accounts for, or to the right to increase the percentage, or enter a value in the text box between Value between -200% and +200%.
4. Drag the slider to enter a value for the "Constant" option. This option adds a channel with different opacity to the output channel.
5. If you want a grayscale image, select "Monochrome" to apply the same settings to all output channels, creating a color image containing only gray values. In the image to be converted to grayscale, the ratio of each source channel to gray can be adjusted separately. If you select and then deselect the Monochrome option, you can modify the blend of each channel individually to create an image of a specific hue.
6. Click "OK" to complete the operation.
3. Use channel mixer for image processing
1. Color image color adjustment
For example, if there is a landscape image, you can see at a glance that there is a problem with the color of the grass in the picture. The color of the grass is bluish and lacks green. So find a way to increase the Y value in the grass color. In order not to affect other colors, the generally more convenient method is to use the selective color correction tool (SelectiveColor) to process, use cyan color as the processing object, and add Y in cyan, but the effect will not be very good. The reason is that in the color of grass, the content of Y mesh itself is very small (for example, reading the color value of a representative point is C64%M24%Y7%K14%). If you want to increase the Y mesh content on this basis, Size is more difficult.
It is very simple to process this image using the channel mixer. Since the Y dot size in the picture is mainly increased in the cyan area, the existing C dots in the cyan channel can be directly used as a basis to increase the Y dot size in the yellow channel. This processing will not change the original level of the image. For the original image with a large C value, the added Y is larger. For the original image with a small C value, the added Y is smaller. The final obtained level is consistent with the original one. Here, the yellow channel is used as the output channel, and the color information of the cyan channel is used to increase the yellow information of the corresponding image points. * Do this once, and the green grass in the picture will immediately turn green.
This example illustrates that when a certain channel lacks color information, it is very effective to use the channel mixer to borrow color information from other channels. To use the channel mixer well, you must have a deep understanding of color, analyze what colors need to be added or subtracted, and what channels should be used as output channels.
2. Use the channel mixer to adjust image saturation
Increasing black or increasing color dots of the opposite color can reduce the saturation of the image. Using this principle, adding black or the opposite color to the color to desaturate can achieve the goal. Likewise, lowering blacks or lowering dots of the opposite color within a color can increase the saturation of an image. Using this principle, reducing the dot size of K in the color to increase saturation or reducing the dot size of the opposite color can achieve the goal. For example, the channel mixer can be used to increase the saturation of the color C80%Y100%K20%: first analyze that the color should be green, and the opposite color of C80%Y100%K20% is K20%. The purpose of increasing saturation cannot be achieved with the Hue/Saturation tool. This can be achieved by using the channel mixer. Select the output channel as the "black" channel, and adjust the cyan or yellow slider of the source channel to the left to change the color to C80% and Y100%.
3. Use the channel mixer to create grayscale images
Sometimes we need to convert a color image into a gray image. If we directly perform the conversion to "grayscale" operation in the color mode, we may not get the desired results. Because this conversion is performed according to the depth of the color, the dot size of each channel is not considered. The shades of yellow, magenta, and cyan are different. If you use a channel mixer for conversion, you can make targeted adjustments to adjust the contribution of each channel in forming gray. Select monochrome, and then adjust the size of each channel, that is, add the dots of each channel to the black channel according to the proportion in the picture. The color mode of the final image remains unchanged. If the original CMYK color mode is used, only the black channel has color information, and the other three channels are all 0%, which is white.
4. Use the channel mixer to create an image with a certain tone
Using the channel mixer, you can also perform creative designs to bias the image to a certain tone and obtain unexpected effects. The following is explained using Figure 7 as an example.
The first step is to perform the channel mixer operation, select "Single Color", and then remove the "Single Color" selection. At this time, the channel mixer becomes as shown in Figure 12, and the output channel is displayed as "black". At this time, the channel tool shows that only the black channel has an image, and the other three channels are blank.
The second step is to select "Cyan", "Yellow", and "Magenta" in the output channel and adjust the sliders in the channel mixer until a satisfactory result appears.
The third step, click "OK" to end the operation.
