The Set Channels effect can be used to switch channels. AE has more tools by far to control color than Photoshop. There are at least a half dozen different ways to do what you want in AE that I can think of.
OK, good news.
But can you at least list 1 procedure to invert B/R channels ? Then we can investigate further ourselves
I did that. If you used curves to invert the red and blue in Photoshop use curves in AE. If you want to swap the channels use a set channels.
AE is Photoshop on steroids. It will do everything and more that you can do in Photoshop and most of the color controls are identical.
If you don't know how to do something use the search help the field at the top right corner of the app and check out the community resources.
Great Rick. We will check that and i will try to revert one day with a possible video ;-)
Thanks you for your support
