HMM. Thanks to my wife for the idea. This is a close up of a silicone scrub pad from the kitchen. I really tried to get the fibers and dust off it, but it held onto them like crazy! This was a little challenging to light, the image preview on the camera did not indicate how blown the red could get from the flash. It took some trial and error and several trips to the computer to work out the proper flash distance and angle. Strobist info: One YN 568EXii to the left of the camera, modified with a small softbox and fired at 1/2 power. The YN was attached to the camera with an OCF cord.
