In my recent search for a digital slr, I came across something that should have been obvious, but I'd never really thought about: no matter how good they claim to be, phone cameras simply aren't any good for serious pictures. For quick pics to share on a phone or convey something you've seen, sure; but to trust your precious memories to? No way. Even compact cameras are mostly good for just snapshots.
The Evo's camera seems to be par for the course. Unless your subject is very still, and you have good lighting, good luck getting a crisp image. On the recommendation of another forum member, I purchased Vignette. It takes much nicer pics than the stock camera app, but again, it's still installed on a phone and thus has its limitations.
