Not a universal standard, but many SLRs use a 2.5mm jack plug that simply shorts some contacts. I remember when I got my first camera that supported electrical/electronic shutter release. There's nothing wrong with a cable release when you're manually operating the camera next to you, but the only common and reliable way to do it from any distance was an air release. I had one, good for about 50 feet. The electrical release, though, meant I could easily do all sorts of things previously only available with fairly complex and expensive gadgetry. It was trivial to make something that fired the camera in response to a sound, a flash of light, or the interruption of a light beam, or a periodic timer. Now virtually all SLRs, most bridge cameras, and many compacts support electronic and IR triggering, and the cost of the trigger device is about the same as a decent cable release. Somewhat less, if you already have an iPaq, iPhone, or Android phone and only count the software cost. -- Pete Peter Turnbull Network Manager University of York
