The images we ended up with.
A shot of the "photo shoot", featuring Diana, trying to help me figure out correct camera settings, etc. I had ordered gradient photo paper, which finally came in, and we installed in into my homemade "light box". I used a large box (one I had hanging around since 2004 because one of my wheels came packed in it and I just KNEW I would need it for something, someday), cut areas out of three sides, painted it white and attached tissue paper in the holes. Then we took 2 PVC pipes with heavy bases and clipped on some reflectors with 100watt fluorescent bulbs. There was a wild assortment of other lights, cords, boxes, etc to help position room lighting.
I think this will work pretty well for "on the fly" shots of new work.
