I originally wanted to shoot a used piece of sandpaper but found a container of spackling instead. I just opened the tub and shot the way I found it.
Used a tri-pod and a $2.00 adjustable clamp light w/ a 100W bulb to create some shadows. Took about 25 photos total and liked this one.
Upper left too blurry for me, if the photo showed the same crispness that is in the center I would have found it more appealing. What was the natural color?
