I set up my Canon 30D on my Gitzo tripod near my kitchen window (IE sidelighting). Canon 35mm F1.4L lens, set on F2.0. I let the camera select the shutter speed when I started shooting then did some bracketing/viewfinder viewing to see where the best exposure was. Then, I set the timer (10 seconds) and each time I tripped the shutter I would run around behind the flowers with a different colorful dishcloth (all bought in Provence) and hold it up behind the flowers as a backdrop. I even used a big sheet of tinfoil as a backdrop for one photo.
