That's noise in the sensor. Photoshop may be able to help a bit with
that. Cooling the sensor helps too, but that's probably not practical
for a camera. (It's how astronomers use CCD sensors, I believe. Some
vague memory says that liquid nitrogen works really well here. It
certainly did in an image intensifier demo I saw at the local
astronomy club 30 years ago.)
