工作流程如下:
1. Make a negative of your clip
1.将该镜头反色处理
2. separate the channels of color: RED, GREEN, BLUE
(I used Color Correct and rewired R<-R, G<-R, B<-R for Red, R<-G, G<-G, B<-G for Green and R<-B, G<-B, B<-B for Blue)
2.分离红、绿、蓝三通道
3. create frames of pure color, CYAN, YELLOW, MAGENTA (as pure as possible, use Vectorscope to help out)
3.做青、黄、品红三个颜色的纯色块
4. use logic ops to combine the color separated clips with the frames of color, using Max/Lighten:
combine RED with CYAN, BLUE with YELLOW, GREEN with MAGENTA
4.使用Max或者lighten的逻辑操作将分离出的红色的通道与青色叠加，将蓝色的通道与黄色叠加，将绿色的通道与品红叠加
5. take the results of the RED / CYAN and BLUE / YELLOW and multiply with logic ops
5.将红/青叠加的结果和兰/黄叠加的结果以multiply的方式叠加
6. multiply the results of step 5 and the GREEN / MAGENTA results
6.再将第五步叠加出来的结果与绿/品红的叠加结果以multiply的方式叠加
7. run the results through Negative
7.反色
