Collection of Photoshop Tips

　81. If you use "Path" to draw a path, and the current status of the mouse is a pen, you only press the Enter key on the small keyboard (remember it is the Enter key on the small
keyboard , not on the main keyboard! ), then the path will immediately become the "selection area".

　82. If you draw a path with the pen tool, and your current mouse status is pen, you only need to press the Enter key on the small keyboard (remember it is on the small keyboard Enter, not on the main keyboard! ), then the path will be loaded as a selection immediately.

　83. Hold down the Alt key and click the mouse on the trash can icon on the path control panel to delete the path directly.

　84. When using other path tools, hold down the Ctrl key to temporarily change the cursor to the direction selection range tool.

　85. Hold down the Alt key and click the mouse on the trash can icon on the path control panel to delete the path directly.

　86. When using other path tools, hold down the Ctrl key to temporarily change the cursor to the direction selection range tool.

　87. Click an empty area on the Paths panel to turn off the display of all paths.

88. When clicking several buttons below the path panel (fill the path with the foreground color, stroke the path with the foreground color, and load the path as a selection), hold down the Alt key to see a Series of available tools or options.

　89. If we need to move the entire path or multiple paths, please select the path you want to move and then use the shortcut key Ctrl+T to drag the path to any position.

90. When outlining a path, our most commonly used operation is to outline a single line of pixels, but at this time there will be a problem, that is, the presence of rectangular teeth, which will greatly affect the practical value. At this time we You might as well convert the path into a selection first, and then stroke the selection. You can also get the lines of the original path, but you can eliminate the square teeth.

　91. Converting the selection area into a path is a very practical operation. This function is consistent with the corresponding icon function in the control panel. When this function is called, the required attribute settings will be available in the pop-up MAKE WORK PQTH settings window.

　92. When using the pen tool to create a path, hold down the Shift key to force the path or direction line to be horizontal, vertical, or at a 45-degree angle. Hold down the Ctrl key to temporarily switch to the path selection tool. Press and hold Click the Alt key on the black node to change the direction of the direction line so that the curve can turn; press 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 Shift and select them one by one. Click; when using the path selection tool, hold down the "Ctrl+Alt" keys and move closer to the path to switch to the add node and subtract node pen tools.

　93. To switch whether the path is displayed, you can hold down the Shift key and click the mouse on the path bar of the path palette, or click in the gray area of ​​the path palette. You can also press Ctrl+Shift+H. To switch color modes directly on the Color palette, hold down the Shift key and then move the cursor to the color bar and click.

　Actions Tips

94. If you want to add a new command after a command in an action, you can first select the command and then click on the palette Click the Start Recording button, select the command to be added, and then click the Stop Recording button.

　95. After holding down the Ctrl key, double-click the name of the action to be performed on the action control panel to execute the entire action.

　97. If you want to add a new command after a certain command in a macro (Action), you can first select the command, then click the start recording icon on the palette, and select the Add the command and click the stop recording icon.

Filter skills

98. Filter shortcuts

Ctrl+F - Use the filter you just used again.

　Ctrl+Alt+F - Use the filter you just used with new options.

　Ctrl+Shift+F - Undo the last used filter or adjustment effect or change the composition mode.

　99. In the filter window, press the Alt key, and the Cancel button will turn into a Reset button to restore the initial state. If you want to enlarge the size of the image preview in the filter dialog box, directly press "Ctrl" and click the preview area with the mouse to enlarge; otherwise, press the "Alt" key and the image in the preview area will quickly become smaller.

　100. The first line of the filter menu will record the usage of the previous filter to facilitate repeated execution.

　101. On the layer panel, you can adjust the opacity and color mixing of the filtered effect (the object of the operation must be a layer).

　102. Feathering the selected range can reduce the abrupt feeling.

　103. When using the filter of "Filter" → "Rendering" → "Clouds", if you want to produce more obvious cloud patterns, you can hold down the Alt key before executing the filter. Command; to generate a low-diffusion cloud effect, hold down the Shift key before executing the command.

　104. When using the filter of "Filter" → "Rendering" → "Lighting Effect", if you want to copy the light source in the dialog box, you can first hold down the Alt key and then drag the light source. Replication is possible.

　105. Process the selected area. If no area is selected, the entire image will be processed; if only a certain layer or channel is selected, only the current layer or channel will be processed.

　106. The processing effect of the filter is measured in pixels, which means that the same parameters will produce different effects when processing images with different resolutions.

　107. In RGB mode, you can use all filters on graphics. Text must be turned into graphics before you can use filters.

108. When using a new filter, you should first experiment with the default settings, then try a lower configuration, and then try a higher configuration. Observe the process and results of the following changes. Work with a smaller image and save the copy of the master file instead of using Undo. This allows the operator to compare the results and note which settings he really likes.

　109. Before selecting a filter, place the image in a newly created layer and then apply the filter to that layer. This method allows the operator to blend the effect of the filter into the image, or change the color blending mode to obtain the desired effect. This method also allows the operator to change the filter effect of the image at any time according to his or her own ideas during the design process.

　110. Even if the operator has already processed the layer with a filter, the "Fade..." command can be selected. When using this command, the user only needs to adjust the opacity and also change the color mixing mode. The operator can optionally apply filters to the layer before ending the command. Note that if you use "Restore", you can no longer change it.

　111. Some filters can process a single channel at a time, such as the green channel, and can get very interesting results. Note that any filter can be used when working with grayscale images.

　112. Use filters to process data on the Alpha channel to get exciting results (grayscale images can also be processed), then use this channel as a selection, and then apply other filters, through This selection processes the entire image. This technology is particularly useful for crystal refractive filters.

　113. Users can break the appropriate settings and observe what effects occur. When users set filters out of the ordinary, they can sometimes get wonderful special effects. For example, setting the parameters for Virtual Mask or Dust and Scratches to a higher value can sometimes work particularly well to smooth out the color of the image.

114. There is a technique that can produce better special effects, which is to do the same thing (not too many times). This technology is particularly good in Western Europe for operating filters. Of course it can also be used with other filters. Users can also use different settings of the same filter, or use completely different filters, on the same selection multiple times to see the effect.

　115. The effect of some filters is very obvious. Subtle parameter adjustments will lead to obvious changes. Therefore, you must choose carefully when using them to avoid losing the effect of each filter due to excessive changes. style. Images that handle transitions can only be used as samples or examples, but they are not the best works of art. The use of filters should also be done selectively according to the needs of artistic creation.

Layer Tips

　116. To move the currently selected layer up: press the "ctrl +]" key combination to move the current layer up. Turn over one layer; press the "ctrl+[" key combination to turn the current layer down one layer.

　117. Use the mouse to drag the layer to be copied to the "New" icon at the top of the panel to create a new layer.

118. When moving a layer or selection, hold down the Shift key to force a horizontal, vertical, or 45° movement.

　119. When moving a layer or a selection range, press the arrow keys on the keyboard to move 1 pixel at a time.

　120. When moving a layer or selecting a range, first hold down the Shift key and then press the arrow keys on the keyboard to move 10 pixels at a time.

　121. To delete a layer directly, you can hold down the Alt key and then move the cursor to the trash can on the layer control panel and click the mouse.

　122. After pressing the Ctrl key, your move tool will have an automatic selection function. At this time, you only need to click an object on a certain layer, and Photoshop will automatically switch to The layer that the object is on; but when you release the Ctrl key, your move tool no longer has the auto-select function, making it easy to prevent accidental selection.

　123. You cannot drag multiple layers simultaneously to another document in the Layers panel (even if they are linked) - this will only move the selected layer.

124. To organize multiple layers into a group, the fastest way is to link them first, and then select the Group Linked Layers command (Ctrl+G). When you want to move multiple layers between different documents, you can use the move tool to drag multiple layers between documents at the same time. This technique can also be used to merge (Ctrl+E) multiple visible layers (because when the current layer is linked to other layers, the "Group with Previous Layer command" will become the "Group Linked Layers" command).

　125. Hold down the Alt key and click between two layers in the layers panel to group them together. This is useful when some layers are linked together and you only want to group some of them. Because the group command (Ctrl+G) will be converted to the group link layer command (Ctrl+G) when the current layer is linked to other layers.

　126. Double-click the layer with the word "T" in the "Layer Control" panel to edit the text again.

　127. Hold down Alt and click the eye icon in front of the desired layer to hide/show all other layers.

　128. Hold down Alt and click the brush icon in front of the current layer to unlink it from all other layers.

　129. To clear all layer effects on a layer, hold down the Alt key and double-click the layer effects icon on the layer.

　130. To turn off one of the effects, hold down the Alt key and select its name in the "Layer" → "Layer Style" submenu; or you can use the Layer Effects dialog box Unmark it as "Apply" in .

131. Here’s a time-saving way to add adjustment layers: Just hold down Ctrl and click the “Create New Layer” icon (at the bottom of the Layers panel) to select the adjustment layer you want to add. type!

　132. 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 X will be displayed to indicate that the mask is turned off). 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.

　133. Press 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; hold down the Alt key and click " The mask added by the "Add Layer Mask" icon hides the contents of the current selection.

　134. 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 from the list The name of the layer makes it the current layer.

　135. Hold down the Alt key and click the right mouse button to automatically select the uppermost layer of the current point, or turn on the automatic layer selection option in the Move Tool Options Panel to achieve this.

　136. Alt+Shift+right-click to switch whether the current layer is linked to the top layer.

　137. When we need multi-layer selection, we can first use the selection tool to select an area in the file and draw a selection virtual frame; then hold down the "Alt" key, when the cursor becomes When there is a "+" sign with a small "-" in the lower right corner (this means reducing the selected area or pixels), pull out the second box inside the first box; then hold down the "Shift" key. When the cursor changes to 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. Irregular objects can also be selected using this method.

　138. 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.

Color Tips

139. Photoshop is a 32-bit application. In order to view the file correctly, the screen must be set to 24-bit color.

　140. First execute the "View" → "New View" command to generate the relevant new window, and then execute "View" → "Preview" → "CMYK" to watch the two modes at the same time Image.

　141. Click the eyedropper or crosshair on the window to change the size and color mode from the pop-up menu.

　142. 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.

　143. Click in 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 one. Color, hold down Shift and click to replace a color.

　144. You can exchange color data 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. .

　145. When opening the Color Range dialog box, you can press the Ctrl key to switch between image and selection preview. If you press the Shift key, the straw will turn into a plus straw with a "+" sign, and if you press the Alt key, the straw will turn into a minus straw with a "-" sign.

　146. Press Shift+Backspace to directly call up the coloring dialog box.

　147. To switch the color mode directly on the color selection control panel, hold down the Shift key and move the cursor to the color bar and click the mouse.

　148. To convert a color image into a grayscale image, the usual method is to use "Image" → "Mode" → "Grayscale", or "Image" → "Decolor" . But now there is a way to convert colors to grayscale in a more detailed way. The step is to first convert the image into Lab color mode: "Image" → "Mode" → "Lab Color", then go to the channel panel, delete channel a and channel b, and you can get an image with a more delicate grayscale .
Image processing skills

149. Press the Ctrl key and click the preview area with the mouse to enlarge the image; press the Alt key and click the preview area with the mouse to reduce the image.

150. Make pictures with transparent backgrounds

Generally speaking, pictures with transparent backgrounds on the Internet are in GIF format. In Photoshop, you can first use the command "Image" → "Mode" ” → “Index Color” to convert the image into 256 colors, and then use the command
File\Export\GIF89a to output the image into a GIF file that can contain a transparent background. Of course, don’t forget to use the Photoshop option in the command window. Color dropper sets some colors in the picture to transparent colors! When saving the file, do not choose to save or save as, but directly select "Output GIF" and then select the transparent color. If you need the transparent parts to be white, select white, and so on. When making pictures, hide the background image and adjust it. Then Save for Web can be transparent.

151. When writing Chinese characters on a GIF, why are the writing discontinuous?

Convert GIF to RGB first, then convert back to Index Color after writing.

152. If the bright colors of the image are excessive due to the execution of the USM sharpening command, you can first convert the image to Lab color mode, and then execute the USM sharpening command in the brightness channel. This will not only To achieve the purpose of clear image, it can also avoid the impact on the color.

153. To check whether the image input by the scanner is ideal, you can open the information palette and observe that the bright and dark values ​​of the image reach 240 and the dark value reaches 10, indicating that the image contains sufficient details.

154. If you want to convert a color picture to a black and white picture, you can first convert the color mode to Lab mode, then click the brightness channel in the channel panel, and then execute "Image" → "Mode" → "Gray" "degree" command, because the color gamut of Lab mode is wider, the converted image will have richer layers.

155. When using Photoshop, we often need to find suitable material pictures from a large number of libraries. In this case, ACDSee can be used to help. You can arrange the ACDSee window and the Photshop window on the screen at the same time, and then Use the mouse to drag the selected picture in the ACDSee browsing window (you can select multiple files at the same time by pressing the Ctrl key) to the Photoshop window. Wait until the small "+" icon appears under the mouse pointer and release the mouse. The picture will be opened in Photoshop. .

156. What pictures are suitable for weight loss

In general, we should make corresponding weight loss measures based on the picture quality we require. There are also some pictures that always need to be modified. If you easily merge them and click save, your future modification work will become complicated. Because after saving, you can no longer restore and split the layers, so you should think twice before doing so. Therefore, don’t blindly pursue capacity and ignore quality, which may cause unpredictable trouble in the future!

157. Image File Weight Loss

Resize images: A larger size image takes up more disk space because it has more pixels. But if you try to use the WIDTH and HEIGHT attributes in the markup to resize the image, you will be disappointed because that will not save download time.

Use thumbnails: Set a very small version of the image so users can click on it to see the full image. But you should indicate the full image size next to it so users can decide whether to view the full image.

Storing GIFs as JPEG: JPEG compression is best for images with many colors.

Increase the compression ratio: If it is a JPEG file, you can resave it with a higher compression ratio to reduce the file size. But don't forget the price: higher compression ratios reduce image quality.

Reduce color depth: The color depth of a GIF image is at most 8 bits (256 colors). Each pixel stores less information and the final file will be smaller.

Adjust the contrast level in an image: Most graphics software provides heavy retouching options such as gamma correction and highlight/midtone/shadow to change the content of an image. contrast. Reducing these values ​​usually reduces file size.

Suppress dithering: Dithering refers to using colors in the existing palette to approximate colors that are not in the palette. Dithering increases GIF file size.

158. How to lose weight on pictures with fonts

Many times we like to use the "Font" function of Photoshop to add a few words to the picture to make the picture more beautiful. But this finishing touch may make the space occupied soar in vain from tens of K to a capacity counted in M. Strange, why is there such a sudden change?

In fact, when faced with this situation, after you merge the layers, use other tools such as ACDSee to convert the format or save it as another format, and then delete the original image, it will naturally become smaller! Generally, it is more appropriate to save it as .jpg.

If the quality requirements of your picture are not too high, you can merge the layers first and then convert it to index color (below 256 colors) or control the size based on the .jpg format.

159. File weight loss

For example, if you save a *.TIF file in Photoshop, how can a file that was originally over 100K become over 3M? In fact, you only need to change the format and then delete the original file.

160. What format should the black and white pictures be scanned into?

If it is a chart, use gif, if it is a photo, use jpg. It is recommended to convert black and white pictures to grayscale first and then save them as gif; if the color is below 256, it is best to use gif - the file size is small and there is no loss of quality; if it is true color, it must be jpg.

161. Transition from real to virtual

How to achieve a gradient from high to low opacity of a selected area or layer in Photoshop? It's very simple. Just feather the selection or make a layer mask, create a new layer and make it a black and white gradient, and then merge the layer selection screen that needs to be effected.

You can also use a gradient mask to transition this area or layer from 100% opacity at the top to 0% at the bottom. These percentage values ​​can also be changed at will.

162. Image mixing and overlay

In advertising design, image synthesis and overlay are often used. In fact, the function is very simple:

Open the main image as the background image.

Then open another picture, Crtl+A to select all, Crtl+C to copy.

Back to the main image, Crtl+V to paste. A new layer appears here. In this layer, select the mode as Multiply or screen. At this point, the two images have been superimposed. Finally adjust the position of the image to the best.

A very artistic effect has appeared, you can also clone your twin!

163. How to realize the function of drawing dotted lines in Photoshop

Double-click the Brush you want to use, change 100% in the Spacing area to be larger, and a gap will be left, then use Brush Just paint. First draw the path, define Brush: Space is set above 200, open the Path panel - Storke Path.

How to overlap two images of the same size with a semi-transparent effect?

In the layer panel: you can change the transparency of the upper layer, or change the blending mode of the layer.

164. To remove burrs

You can try to use the path tool or magic wand to outline the outline of the image, then use "Feather" of "Select", then invert the selection and delete, it may be better .

165. How can I save the extracted image without the background color?

"Copy" the area selected by the dotted line, then "Paste", then delete the bottom layer, and finally "Ctrl" +S". Note that the storage format should be .PSD format or .EPS format or .AI format.

166. Quick filling

Open the picture to be filled, execute Ctrl+A, select all images, execute "Edit"→"Define Pattern", define the picture as a pattern and execute "Edit"→ "filling".

167. Remove texture from pictures

(1)Scan a picture from a pictorial or magazine

Generally, texture is caused by the printing of pictorials or magazines It is caused by the rough texture of the paper. When scanning, the dpi value should be set higher. The higher the resolution, the larger the scanned image will be, and the higher the relative fineness will be. A higher resolution will create good conditions for the next step of image reduction and filter processing.

(2) Adjust the image to the appropriate size

Select the "Image Size" option under the "Image" menu, the "Image Size" dialog box will pop up, and determine the limit ratio option under it To check the box, change the pixels after Width to percentage in the pixel size. The Width value at this time becomes 100. At this time, you can enter the required percentage value to reduce the image proportionally. After the reduction, the texture has been slightly reduced.

(3) Use Gaussian blur to eliminate mesh

Select "Show Channels" in the "Window" menu, and the channel panel will appear. The four channels are RGB, Red, Green and Blue. Select the Red channel and the picture will appear in black and white. Select "Blur" → "Gaussian Blur..." in the "Filter" menu, and the Gaussian Blur dialog box will pop up. Adjust the radius value to control the blur range so that the mesh in the Red channel is almost invisible and the image content is slightly blurry. Then adjust the Green and Blue channels respectively in this way to make the mesh in this channel disappear. Finally, return to the RGB channel. At this time, the picture has no interference from the mesh. Note: The value of Radius cannot be set too large to avoid excessive impact on the RGB channels and making the picture hazy.

(4)Adjust the final effect

If the mesh is too clear and the radius value is set to a large value, the image in the RGB channel will be somewhat blurry. If you want to make the content of the picture clearer, you can also perform the "Sharpen" clearing effect in the "Filter" menu. Finally, use the "Adjustment" → "Levels" or "Brightness/Contrast" options in the "Image" menu to set the contrast and other values ​​you need to achieve the final satisfactory effect.
