Sure, Mario.
For the last two build reviews I made photos in raw format with Pentax K-x camera in a self-made lightbox from cardboard and whatman sheets (1 sec exposure time and f/32) . Light comes from 2 halogen lamps - 500W, I took them from a local supply store for 10 euro each.
After that I transfer images into Adobe Lightroom - very useful software, you can work with all set of images at a time, not 1-by-1 like in Photoshop. So, in Lightroom I just press "auto whitebalance", "autotone" and then export with an option "sharpen for web" on. I think it is quite easy to make images of unpainted model, but I am still very bad in shooting painted ones.
