I have a $8 lamp I got from Walmart long ago, and the shade for it is a translucent plastic bowl... with hole already cut in it. That would work well also.
Oh, and I downloaded my camera manual and learned how to adjust white balance! I took this photo earlier - I had to adjust levels a bit in Photoshop, but it's a heck of a lot better than it was. My lights also need different placement, but I'm on the right track.
Thanks so much, Evan, for posting this wonderful tutorial, and Shari, for clueing me in on camera usage!! : )
