The last time I know for sure I took pictures on film was on my summer vacation, 1994. That roll of film sat, un-processed, for years in my Canon ML. I don't think I ever developed it and I have no idea where it's gotten to.
I was pondering this as I was digging through boxes in the attic looking for my old AE-1 Program and coming to the reluctant conclusion that I must have either sold it back during one of my broke times in the Nineties or given it away in the early Aughties after having bought the Sony Mavica.
Anyhow, that means it's been twenty years since I shot pictures on film and that has caused me to develop an unusual tic I noticed yesterday. With the Leica, I'd carefully compose the shot, squeeze the shutter button gently so as to not disturb the image... and immediately yank my face away from the eyepiece and glance at the back of the camera to see what I'd got, staring dumbly at the blank metal and leatherette because I expected there to be a little screen there with my picture on it.
As a shooter, this bugs me. Prairie-dogging up over the pistol sights to look for the hole after every shot is poor form, shows a lack of follow-through, and causes misses. If you're calling your shots, you should know where that bullet hole is. I don't know how that translates to cameras, but it seems like it should.
ETA: Kevin informs me that this habit is called "chimping".
