Today, I found a new way to flub a LF shot. Shooting 4x5, sheet #10 was the next one up. I loaded it into the back with the #10 label facing me (think about that). Pulled the darkslide and DUHHHHHHHHHHHHHHHHH!!!!
I'm seeing the film through the ground glass.
Hadn't done that one before!
The wonders of Large Format. At least I caught it when it happened.

Well, look at the bright side, Alex. At least it was "only" 4x5 and not 8x10 or worse, 7x17.
