I use a Sony Cybershot DSC-W80 as my camera and about 2 years ago I started seeing a dark spot in my pictures, I did a bit of research, discovered I likely had dust on my internal sensor, looked at how to clean it off and it just looked so intimidating for me, who knows nothing about cameras in general. I took it to Wolf camera who said they'd charge like $250 to clean it so needless to say, nothing was done. I ignored it but it's gotten worse, to the point that I can't ignore it anymore. I took this picture pointing up at my white ceiling zoomed in to show what I mean. From what I've read this is a problem usually for cameras with changeable lenses but I haven't found any solutions for a basic point & shoot camera. Is there any way I can go about fixing this?
