I use Leicas, both M and Screwmount. Everything's 1967 and prior. No meters, and nothing moves unless I push it. I keep a Pentax spot meter for reference if I'm ever unsure. My exposures are almost always just good guesses. For my work this is essential, it's intuitive, it's simple. I find automatic settings, exposures, and focus to be quite difficult to deal with, although most seem to do fine. It's all too general, and adds another interface that I have to bargain with to get the desired setting. I don't have anything against automatic settings, I just don't see why they are preferable for personal work. I never have a problem spinning my shutter dials, aperture, or focus ring to the correct setting at a moments notice. As far as printing and developing, sure you could have an assistant, but the photographing itself, why would you want someone, or in this case something, else doing it for you? (Or at least trying to).
I am also 23.
