I did not know that. Now I do. A couple of thoughts: 1) Wow, that must really suck juice! 2) I presume, then that when one hits the shutter release there must be a delay of about a second or so to the exposure? and, 3) One certainly is letting everyone in close proximity to the camera know that they're about to get their picture taken! <vbg> (not that that's always a bad thing, just that it wouldn't be very good for candids - for group or posed photos, it would be no problem) Thanks again! cheers, frank -- "It's about time we started to take photography seriously and treat it as a hobby." -Eliott Erwitt
