I currently have a Nikon D90 which I love and I've learned about photography on it. I get the basic concepts and how aperture, shutter speed and ISO play together, etc. However I always feel as though I missed out on something by never shooting a film SLR (I've had my share of film cameras over the years but never an SLR). My line of thought is that it might force me to slow down and think about the shot more while paying attention to the meter and framing of the shot for example. With my digital I get instant gratification (or disappointment) and can re-shoot endlessly until I think I got it right - with film it's more of a surprise when you have it developed. I can pick up a Nikon N75 for $40 locally so the initial cost wouldn't be much at all to get started, plus all of my current lenses will work on it. Thoughts? Am I on the right train of thought?
