How to reproduce the various 'Blend' modes of PS in PixInsight?

[RobF2]

Or even some pre-saved process icons calling those formula for each screen blend?
Don't know how you'd reference the 2 images though?  (you could drag icon on to the target image, but not sure how you'd link back to the first image?)

Good idea.

I have never looked into The Gimp - I never saw a need, not as a PI user. Somebody might have some 'inside knowledge' though . . .

You can define a target image by replacing IMG1 (or IMG2) by $T, but the other image must be set manually by ID (to my knowledge...). I think it may be practical alternative have a simple script that allows to select the two images and the type of operation. (And if this writen by a advanced PJSR guru, might be with a preview )

Well, thanks to Rogelio for making me 'wonder' - the end result has been simply fantastic - thanks to everyone for the hard work!!

It looks as if another PS 'barrier' can be pushed to one side, even though a little bit of 'tidying-up' might be needed. With these code snippets in place, the notion of 'Layers' draws a step closer

I'm glad I asked the question now
