Nov 17 2005 - Timer circuit Mk I

Built myself one of these (see www.hiviz.com) to try out some high-speed flash photography. Took all evening to get it to work so there was no time to actually use it (see November 18th/19th for that).

Canon EOS 5D ,Canon EF 24-105mm f/4L IS USM
1/160s f/8.0 at 45.0mm iso100 with Flash full exif

other sizes: small medium original auto

Via a sync cord to the flash

Right, but when it is connected to the camera how is it connected?

Actually, none of it connects to the camera - there is a lead to connects to the flash but that's not connected in this picture. The camera shutter is held open for a few seconds at a small-enough aperture and a dark enough room that it does not register any significant image except when the flash fires.

Cool stuff. So what part connects to your camera?
