D90 sample question
I was looking at the samples at the end of the D90 preview and got to the 3rd from the last, the antenna. When I downloaded the full sized image, I was shocked to see an image that looked for all the world like a scan of a dirty slide, particularly around the rectangular grid element. There's black spots (likely dust on the sensor) and white spots and streaks. What IS all that stuff? Its DSC_0258.jpg.
