1. The use of Boolean operations
1. Boolean operations are used in the graphics tool group, the shortcut key "U"
2. How to use: All operations are performed under the same layer. Before performing the Boolean operation, first use the path selection tool, the small black arrow, and the shortcut key "A" to select the graphics you want to operate.
3. The six forms of Boolean operations are searched in the property bar.
4. Picture example display:
2. Layer styles
1. Layer style is to add simulation effects to your layers, groups, and smart objects.
Layer styles are powerful and can easily and quickly create image special effects with various stereo projections, various textures and lighting effects. Editing is also very convenient.
2. There are three ways to find the layer style: the bottom of the layer and the new layer are together, the second position on the left (fx)
3. Picture case
Clock effects: such as gradient, drop shadow, bevel relief, outer glow, inner shadow, stroke and other effects, this small icon is synthesized.
4. Precautions
a. size, and its resolution
b. Color and gradient angle
c. Whether the angle of the rounded corners is appropriate and whether the whole is beautiful
d. Don't give it too dark, you can reduce the opacity
e. When adjusting the angle of the light, it should be noted that the global light is enough to be checked. If it is checked, cancel it so as not to affect the lighting effect of the entire object.
f. The pointer scale of the dial, whether the rotation angle is correct, the shortcut key used is, CTRL+ALT+T After adjusting the angle, use the shortcut key to "reproduce CTRL+ALT+T"
3. Toning of the image
Image-adjustment properties in the menu bar can adjust the color of the image.
And the commonly used shortcut keys are also more convenient
The second is the fourth position of the circular half-empty shape at the bottom of the layer panel, which is also possible
3. When adjusting the image, you can refer to the window in the menu bar and the histogram inside to adjust the image. The histogram can show what color is missing in the image.
4. When adjusting the color of an image, if you only want to adjust an image, you just need to press and hold the ALT key of the keyboard + the left mouse button, and a "downward black arrow and a white square" will appear;
If you want to cancel, press and hold the "ALT key + left mouse button" again.
5. When the smart object adjusts the color, it can be modified repeatedly, and the adjustment layer appears below.
6. The most commonly used colors are: "Level CTRL+L", Curve CTRL+M" and "Hue Saturation CTRL+U".
7. When adjusting the color with Hue Saturation, when the black and white image cannot be adjusted, you can click Colorize to add a layer of color to the image.
总结：
我觉得学习一门课程要有耐心，要肯下功夫，上课跟着老师的思维走，课后不仅要认真做当天的作业，也要对知识点反复的练习和琢磨。
最后要感谢老师耐心的讲解与指导，努力提高自我的水平，不辜负老师的期望。
一.布尔运算的运用
1.布尔运算是在图形工具组中使用，快捷键“U”
2.使用方法：都是在同一图层下运算，在进行布尔运算之前，首先用路径选择工具，小黑箭头，快捷键是“A” 选取你要运算的图形。
3.布尔运算的六种形式，是在属性栏里面查找。
4. 图片实例展示：
二.图层样式
1.图层样式就是针对你的图层、组、以及智能对象做模拟特效性的添加。
图层样式的功能强大，能够简单快捷地制作出各种立体投影，各种质感以及光景效果的图像特效。编辑起来也特别的方便。
2.图层样式查找的三种方式：图层最底下与新建图层在一起的，左边的第二个位置（fx）
3.图片案例
时钟的效果：如渐变、投影、斜面浮雕，外发光，内阴影，描边等多种效果合成的这种icon小图标。
4.注意事项
a.的大小，以及它的分辨率
b.的颜色以及渐变的角度
c.的圆角的角度是否合适，整体是否美观
d.不要给的太黑，可以降低一下不透明度
e. 调节光的角度时候，应该注意全局光是够勾选，如果勾选了，就将它取消，以免影响整个物体的光照效果。
f. 表盘的指针刻度做法，旋转的角度是否正确，其中使用的快捷键是，CTRL+ALT+T 调节好角度之后在用快捷键”再制CTRL+ALT+T”
三.图像的调色
在菜单栏中的图像—调整中的属性可以对图像进行颜色的调整。
以及常用的快捷键也是比较方便的
第二种是在图层面板底下的圆形半空形状的第四个位置，也是可以
3.当调节图像的时候，可以参考菜单栏中的窗口，里面的直方图来进行调节图片，直方图可以看出这个图像缺少什么色彩。
4.当调节图像颜色时候，只想对一张图像进行调节，只需要按住键盘的ALT键+鼠标左键，会出现“向下的黑箭头和一个白色的正方形”；
如果要取消的话就再次按住“ALT键+鼠标左键”就可以了。
5.智能对象调整颜色的时候，可以反复的修改，调整层是出现在下面的。
6.调色经常用的是：“色阶 CTRL+L”、曲线 CTRL+M”“色相饱和度CTRL+U”。
7.当用色相饱和度调节颜色时候，当黑白图像无法调整时候可以点击着色来给图像添加一层颜色。
