I have noticed that many people use photoshop to correct things in their images. I am curious about the number of us 3D artists who "doctor" , "change" or "add to" your images after they have been rendered. If you do, what do you think the limits are, if any?

I personally dont like to change things once its been rendered. I think its more fun to challenge myself to get it right in bryce. It's more work but I like it.

What do you think?
