Roughly 332 shots, and I came away with 4 I liked. This was with my 85mm f/1.4 and an extension tube (mostly for a shorter minimum focusing distance, less for the magnification).

I love incense smoke. My favorite scent in particular is heavily scented, which means the smoke itself tends to be heavy. Sometimes it drips down the side of the box and pools on the coffee table. I really wanted the detail on the small wisps for this, and the lighting on the box gave a nice contrast as well.
