I hope that this question does not seem too dumb to answer. You say that you make 3000×2000 images using 3DS and that is impressive. But my question is about making hard copy with those images. Before you output these images to a device, do you gamma correct them? Or do you make them what they should be right in 3DS? I would like to make fairly large color prints and am interested in knowing if any post-processing is really required for best results (or even good results). Thanks for any comments.
