Here is what I have found to be the simplest setup for decent photos...

First, you need a peice of posterboard (Micheals or any craft store), preferrably glossy in white or black. They do have a chrome posterboard that has a mirror effect that is decent also. Then lean it against a wall like a skate ramp (use some sort of weight to hold it in place), underneath a light that points down. Make sure to use a bright white light to keep the color as natural as possible. Finally, I set my D70 on auto without the speed flash and end up with pretty good photos! I never adjust the color or the light. I just crop them and they are ready to roll!
