I've been using a hand me-down camera for a few years now. Often times I keep it in my backpack. Recently I realized that there were some dust spots on my photos, so I tried to clean the lens with a blower that was included in the kit. After some trial and error the dust spots are still present, if not worse. I put a neutral photo with heavy dehazing to illustrate how rough it's gotten. With the state of things I'm thinking I might've messed something up, and it might be a censor issue with the camera body. What am I doing wrong here?
