Ok so heres the deal. I have had a Nikon D50 for a few months now and I am starting to see some dust in my photos. I Bought a blower, and it removed most of the dust but there are still about 2 spots that are still in the pictures. What do I do. I dont believe that it is the image sensor, but i dont know how to tell. The kit I bought came with some q-tips and a cleaning solution and the cleaning tissuse paper. What do you guys recommend. Should I send it to Nikon to get fix or what? Thanks in advance.
