I feel the same way - there's a greater sense of accomplishment when you allow yourself only a single opportunity to capture what you see in front of you.

In photography parlance we call it chimping - i.e., jumping around like a monkey and clicking the shutter like crazy, trying to get the right shot. Even if you get the right one, you have no idea if it's your skill, luck, or just law of large numbers...

When I shoot film I feel more purposeful - I rarely ever take more than a single exposure of any one particular thing - it also teaches you to be patient, and hold the shutter until you know you have the right shot. On rapid-fire you will often get a good picture, but no idea what makes it good, whereas with film I'm aware that this picture works because, say, I waited until there was no one in the background.

My current favored camera is a Leica R4s - only manual and aperture priority modes, manual focus, manual aperture control, and only 2 metering modes (you only ever need one - center-weighted). When you strip a machine down to the bare minimum it opens a lot of creative doors.
