温度计构造不复杂,不过玻璃容器部分刻画比较难。因为它的轮廓不是很规则,刻画同一部分的高光及暗部的时候需要分两步或多步来完成。
最终效果
<图1>
1、温度计图标大致由下面的几部分构成:玻璃容器、液体、度量条纹等。
<图2>
2、新建一个800 * 600像素的文档,选择渐变工具,颜色设置如图3,拉出图4所示的径向渐变作为背景。
<图3>
<图4>
3、新建一个组,用钢笔勾出器皿的轮廓路径,转为选区后给组添加图层蒙版。
<图5>
4、在组里新建一个图层,填充淡蓝色:#CBD1E2,添加图层蒙版,用黑白渐变拉出右侧透明效果,如下图。
<图6>
5、新建一个图层,填充同上的颜色,添加图层蒙版后用渐变拉出左侧透明效果,如下图。
<图7>
6、新建一个图层,调出当前组蒙版选区,填充暗蓝色:#9A98B9,保持选区,选择菜单:选择 > 修改 > 收缩,数值为2,确定后羽化1个像素,按Delete删除中间色块,效果如下图。
<图8>
7、新建一个图层,用椭圆选框工具拉出下图所示的整体选区,填充白色。保持选区,选择菜单:选择 > 修改 > 收缩,数值为2,再羽化1个像素后按Delete删除。取消选区后添加图层蒙版,用黑色画笔把顶部稍微涂抹一下,效果如图11。
<图9>
<图10>
<图11>
8、新建一个图层,用钢笔勾出下图所示的选区,羽化15个像素后填充暗蓝色:#BABFD9,作为顶部的暗部如下图。
<图12>
9、新建一个图层,用白色画笔涂上一些高光,如图13,14。
<图13>
<图14>
10、新建一个图层,调出当前组蒙版选区,选择菜单:选择 > 修改 > 收缩,数值为2,确定后填充白色。保持选区,再收缩2个像素,羽化1个像素后按Delete删除,得到边缘高光选区。取消选区后添加图层蒙版,用黑色画笔把右侧以外的部分涂掉,效果如图16。
<图15>
<图16>
11、新建一个图层,同上的方法制作左侧边缘的高光,效果如下图。
<图17>
12、液体是红色的,玻璃部分也会有影响。新建一个图层,混合模式改为“柔光”,用红色画笔在液体位置涂上一些环境色。
<图18>
13、新建一个组,用钢笔勾出液体部分的路径,转为选区后给组添加图层蒙版,如下图。
<图19>
14、在组里新建一个图层,用矩形选框工具拉出图20所示的选区,然后选择渐变工具,颜色设置如图21,拉出图20所示的线性渐变。
<图20>
<图21>
15、创建曲线调整图层,把全图调亮一点,参数设置如图22,确定后按Ctrl + Alt + G 创建剪贴蒙版,把蒙版填充黑色,用白色画笔把图23选区部分涂出来。
<图22>
<图23>
16、新建一个图层,用钢笔勾出下图所示的选区,填充橙红色,取消选区后用模糊工具把顶部稍微模糊处理。
<图24>
17、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,用画笔涂出简单的明暗。
<图25>
18、新建一个图层,同上的方法制作液体部分的高光及暗部,过程如图26 - 29。
<图26>
<图27>
<图28>
<图29>
19、在当前组的最上面新建一个图层,用椭圆选框工具拉出图30所示的选区填充橙黄色,再渲染一些高光,效果如图31。
<图30>
<图31>
最后加上刻度及一些高光,再微调一下细节,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.
