>how do you photo thru a dust cloud thrown up as the vehicle >moves away? If go for a forward shot, you'd have probs with >the vehicle's headlights at night. Plus flash/illumination >probs. Still thinkin' about that. You do what Europeans do for speed cameras. Use Infrared flash - the speeder never knows they got caught until the notice arrives in the post, and other speeders don't get warned by the flash that the camera is active. Now there is a thought - I wonder what the market would be for a IR flash detector so you see if the car in front got flashed, and I can slow down before the camera ;)))) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
