That's the whole point of a "lightning trigger". It measures the flash and reacts. However, because of the flash is so short, it's tough for a human to react in time.. and if the camera has significant lag-time, you miss the shot, no matter how fast you are. By putting the sensor for the 'trigger' in the eyepiece of the camera, it will not react to lightning outside the field of view, and so your percentage of 'keepers' goes way up. Still, you need a 'fast' camera and a winder, so you can leave the thing relatively unattended. All this, of course, is for daytime photography. At night, you can still put the camera on 'B' and wait! - ---------- David Young, | égalité, liberté, Victoria, CANADA | fraternité et Beaujolais.
