本教程介绍常见实物的制作方法。重点是实物高光及暗部的把握,需要把立体感渲染出来。大致过程:先用钢笔等把实物的轮廓选区做出来,然后用渐变、加深、减淡工具加强体积感,后期再渲染高光及暗部即可。

13、新建一个图层,用钢笔勾出底部高光选区,羽化1个像素后拉上图19所示的径向渐变。
<图18>
<图19>
14、新建一个图层,用钢笔勾出图20所示的选区,拉上同上的渐变色,效果如图21。
<图20>

17、选择加深,减淡工具把边缘部分的高光及暗部涂出来,效果如下图。
<图27>
18、新建一个图层,用椭圆选框工具拉出一个稍小的椭圆选区,拉上图29所示的径向渐变。
<图28>
<图29>
19、新建一个图层,按Ctrl + Alt + G 创建剪贴蒙版,然后在当前图层下面新建一个图层,用椭圆选框工具拉出图30所示的椭圆选区,拉上图31所示的径向渐变。
<图30>
<图31>
20、可以根据需要添加一些水纹,这一步可以省略。
<图32>
21、新建一个图层,用椭圆选框工具拉出图33所示的选区,拉上图34所示的径向渐变。
<图33>
<图34>
22、把做好的汤圆复制一些,适当排好位置,过程如图35,36。
<图35>
<图36>
23、在图层的最上面新建一个图层,按字母键“D”,把前背景颜色恢复到默认的黑白,执行:滤镜 > 渲染 > 云彩,效果如图37,确定后把图层混合模式改为“滤色”,按住ALT键添加图层蒙版,用白色画笔把碗中的烟雾擦出来,效果如图38。
<图37>
<图38>
最后给碗添加投影,再调整一下细节,完成最终效果。

Photoshop's cost includes direct costs, time and learning curve, resources and hardware investment. 1. Direct cost: Subscription system $20 to $50 per month, purchase hundreds of dollars at one time. 2. Time and Learning: It requires a lot of time and practice, and it is recommended to learn through online courses and tutorials. 3. Resources and hardware: High-performance computers and sufficient storage space are required to ensure hardware configuration to improve efficiency.

Photoshop's core features include layers, selection tools, and adjustment tools. 1. The layer allows independent editing of image parts and supports layer style. 2. Selection tools such as lasso, magic wand and quick selection tools provide precise editing. 3. Adjustment tools such as color level, curve and hue/saturation can adjust images non-destructively.

In Photoshop, the role of layer masks is to allow hidden or displayed portions of layers in a non-destructive manner. 1. The working principle of layer mask is to control the visibility of the layer through black, white and grayscale. 2. The basic usage includes image synthesis, such as synthesising the character image into a new background. 3. Advanced usage can be achieved by using gradient masks to achieve smooth image transition.

Photoshop's powerful features include smart objects and neural filters, while free alternatives such as GIMP, Krita and Photopea do well in specific fields such as GIMP's layer functionality, Krita's digital paintings and online editing of Photopea.

Color adjustment in Photoshop can be achieved through adjustment layers to make the image more professional. 1. Use color level, curve, hue/saturation and other tools to adjust the hue, saturation and brightness. 2. Apply LUT to create unique color effects. 3. Use adjustment layers to avoid image distortion and use the History panel to track adjustment steps.

Photoshop's applications in the real world include artistic creation, scientific research and commercial marketing. 1) In artistic creation, it is used for digital painting and illustration. 2) In scientific research, it is used for image processing and data visualization. 3) In commercial marketing, it is used for advertising design and brand image shaping. The versatility of this software makes it widely used in various fields.
