Generally, I use the miniature roll film cameras because they're light, portable, and take wonderful photos. Having a larger negative doesn't mean a thing to me if it isn't backed up by a better pic, which it seldom is. Much of the romance w/ larger formats is just that, romance. It's sorta neat to "play photographer" on the streets w/ a LF camera. Setting the beast up, talking to curious observers, feeling like you're a "working pro", all that. But at the end of the day I don't see any meaningful differences in the images made by a LF camera and a small one. Yes, you get better tonality (sometimes) and less grain (sometimes), but do you get a better picture? Nope, you don't, you just get a larger one. So w/ me it has nothing whatsoever to do w/ money. I can make a nice photo w/o any camera at all, so that's obviously not the deal. Obviously a LF camera is potentially better suited for architecture or landscape work, and if you just need a big photo you need a big photo, but someone w/ vision isn't bound by these arbitrary rules.
What I find very informative it that 35mm shooters are way at the bottom of this poll in terms of usage. It's almost as if that nonsense about 35mm cameras being for amateurs is playing out here to be a truism. But it's most emphatically NOT true, and I still feel that a lot of the LF usage, and it surprises me to say this, is more about what you look like when you're photographing (to yourself, mostly) than the image that you actually come up with. I thought we knew better than that here. But, we don't. Let's face it, if I managed to come up w/ a digital shot that mimicked one from a wet plate camera, just to use something for an example, people here would be all over me like white on rice. There's a certain amount of smug elitism associated w/ these forums, w/ RFF being the ultimate Big Money end of it, wherein what you use is as important as what you have to say. That's patently crap.
