I took some pictures recently and found little soft black marks on the actual photo. I took a few more pictures to see if they still showed up and they do. I've uploaded a sample of what I'm talking about... http://img168.imageshack.us/img168/8787/pic003it2.jpg (**Make sure to view it at the full 100%!**) I bought a "poofer" thing to get all the little dust particles out of the camera but it's still showing up! Help!! What can I do!?!
