for the past few years i've been using a cheap samsung s630 for pictures of friends and exploring my interest in photography; now i'm planning to apply to college for photography. needless to say, i need to upgrade my camera. the noise on my camera is ridiculous, and i'd like to submit the best quality pictures i can. i have about two years til i'm off to college, should i upgrade to a better quality point and shoot or get a mid-grade DSLR that will last a little longer? i'm definitely open for suggestions: i want something versatile (as a student i'll be shooting a variety of subjects), sturdy, not huge (small hands lol), with a good quality/price ratio. i used to be strictly nikon fan, but i'll take any suggestions. thank you!
