Yep, I've had a few "Dumb and Dumber" moments:
Shooting from a balcony in a muggy 100º church, with no fans or lighting. Look through my Contax 645 viewfinder to take some critical shots ... and it's black. Start frantically field stripping the camera to see what the heck is wrong, seems okay, put it back together, still black ... finally discover I had inadvertently flipped the viewfinder dark slide into place while wiping the sweat off the camera and finder ... which I couldn't see in the dark. :facesmack:
Balcony #2 incident: Shooting a 555ELD and original Kodak ProBack on a tripod. Had the tethered Quantum battery strapped to my waist for mobility. Decided to swap lenses ... turn to reach for the 40mm on the pew and pull the whole rig over ... which promptly tumbles down a flight of marble steps disrupting the wedding I was shooting.
I occasionally have nightmares involving "Balconies".
Every time, and I mean EVERY TIME, I walk an elaborate lighting set-up to a remote location, the 8" sync cord from radio transmitter to camera fails. Do I learn? Apparently not. Had it happen on the last shoot again. I had cleaned and formed the tip before leaviong and must have pulled it to hard when removing the conditioner, just enough that it still worked, then didn't after 2 shots. :banghead: Now I have 5 of them in my pocket ... until the next time when I forget.
