Thats "just me"... Color manipulation should be done (im my personal opinion) through the shaders/material settings, not post work. I do print my images and I do calibrate my monitor, and I get out of the scene exactly what I want... I may run an image through a levels adjustment or play w/ the brightness/contrast controls, but thats for printing sake only, and only to get the print to match what I produce and see onscreen.

Ive never considered my work only "half finished"...

There are 3 kinds of people in the world. Those that can count, and those that can't..
