"coolpix 990 - problems with long exposure (new URL)"
I have recently had to take some images using a 4 or 8 second exposure. I'm getting poor results due to speckled dots all over the picture. Has anyone else had similar results with very long exposure times.

The noise you're seeing is what is normally referred to as 'hot pixels' and is common to all digital cameras to a greater or lesser degree. It typically shows up at exposures of 1 to 2 seconds or more.
