Spilled salt
I got my reverse macro adapter in today, and needed a subject to play around with. Roger's recent sea salt photo inspired me to see what I could do with table salt. I thought this was the best of several variations on the theme.
This was taken with the $70 Canon 50mm prime reverse-mounted on the end of the Canon Digital Rebel XT kit lens, an 18-55mm zoom. The captured image has a bit of vignetting, but it 's better than any other combination I could find, and makes a nice square or sideways crop. Some experimenting taking shots of a ruler showed that I'm getting down to only about 20.5mm in the frame, which by my math is just over the traditional 1:1 ratio that turns a mere closeup into a macro shot.
These were taken using a tripod and lit with a hot bright halogen utility light, since the lens ends up so close to the subject that it shades most of the ambient room light. I used a small aperture and longish exposure to work around the wide-open softness issues the kit lens has. The reversed prime, of course, was wide open but there wasn't much I could do about it.
