Most of us are grown ups, but I figured I'd put a warning in the subject line. This shot is from the same set that I took and posted a few days ago, but this one's a little more gruesome.
Tech specs: Canon 40D (F13, 1/250, ISO 100) + a Canon EFS-60mm macro lens with 37mm of extension (2x) + an MT-24EX macro twin flash (-1 1/3 FEC).
@ raystack: The shutter speed I listed is irrelevant -the ambient light was low, and at F13 and ISO 100 there is no natural light in those scenes. Just set your shutter speed to the maximum sync speed that your camera can handle. I may stop including the shutter speed in future images when there is no ambient light in a scene.
