Gah! Did I ever learn THAT one the hard way.
I got the notches right (had a 50/50 chance), but missed that whole film rail/darkslide rail part and zoinked one of my negs.
But, since this was a wing-it kind of learning experience, I didn't sweat it.
But one question more: How do you manage to grab the film in the tray with the tongs? I couldnt get hold of it to save my life. =P
