BTW, why do you combine your image with gamma? How can you get identical result to beauty pass from Corona that way?
You can't. I was just trying to show how you can use some of the passes even if you dont know the "correct" way of using them ( like myself ).
I have some object (teapot) on slightly reflective floor (plane) and i want to compose my rendering from elements in such a way, that i'd be able to change colours of teapot and plane in photoshop. Ideally i'd like to be able to change colour of teapot's reflection if possible, but that's not critical.
I demonstrated how you can change reflection and object colour in Photoshop,i thought that was the question in the first place. It may not be the correct way of using elements but it works good enough for me. Also , I find it very fast.
