I've designed guitars, furniture and alien landscapes at higher resolutions than you'd be accustomed to. Sometimes it's a pixel-by-pixel color balance change and the clients make me nuts with subtle changes that take weeks (eight-hours a day) to create.
That's kinda' why my posts here don't measure up to my "real" Pshop work in any way. PCS is my entertainment. . . a chance for me to not take the skill so seriously . . . have some fun.
Please post some of your "'real' Pshop work".
I'd love to see something of yours that took took weeks to create.
