I must admit I can get richest effects by working on a ruff trashboard, scanning it and avoiding posterizing or converting it to Black and White linear image. Then I get the coloured by using the selection tool both Magic Wand and Lasso (I worked on iPhoto Plus, a very old image editor that came with my old scanner) with different gradients of sensitivity and similarity. Then came lightning and color adjustments for each selection. And here are the procedure step-by-step, maybe I need to work on enhancing the central object like popping it out from the orange-hell background. What do you think?
