I love using the manual setting with my digital (Olympus PEN E-PL1). It's super-fun, seriously, but these are not digital shots, these are Polaroids. (Were Polaroids) I saved them from nothingness, from being dismissed by me and the viewer, aka you. Whether an exposure issue, or a composition issue, I believe it's all good to use whatever means necessary to make an image special.
That said, it's never, ever okay to try to fool others about process, in my humble opinion. Meaning it's not cool to be dishonest and pretend that any particular photo just came out that way if it didn't. I don't understand why anyone would want to be dishonest about their art anyway. Aren't we all searching for truth to some extent? Process is such an important part of creating an image, might as well own up to it, that's what I say.
