about 14 shots... they were about an inch apart. Only about a half an inch long too! I kept the contrast high. but checked the range with the curves tool... and set the whites to 255. The color one isn't bad.. just liked this one better...
Very unique and creative shot , the only thing drawing my attention away from from the tacts, is there is a bit of speckles and grain/noise in the background. I would smooth the background a bit and tone down the highlights.
