Dust behind/inside my lens...
I was wondering if anyone could tell me the proper way to remove dust behind my lens of my camera. I have a Sony Cyber-shot DSC-W290. It's about 2 and a half years old. I tried using a dusting cloth and compressed air but once the lens in clean, you can see the dust inbetween the lens when you zoom in and out. It's terrible... so much dust that it's actually ruining my pictures. When I try and focus it will not if it's zoomed at all... Please let me know what I can do! Thank you in advance.
