I am considering buying a digital camera to use for both general and aviation photography. My budget is tight, though, and if at all possible, I don't want to spend more than $200 USD or so. I have seen some relatively good 3MP cameras on different websites and was wondering if these would be acceptable in terms of quality or if I am crazy and should never consider a 3MP camera for aviation photography. I don't necessarily need to upload all my shots to Airliners.net, but would a 3MP photo, shot and edited correctly, have a good chance of being accepted? Or is this whole idea a waste of time? Any opinions would be greatly appreciated.
