Photoshop isn't very effective at reducing noise without also losing much
image detail, at least in version 7 and below, though it is supposed to be
better in the latest one. You are better off using specialised software,
such as Neat Image (good but very slow) or Noise Ninja (faster) on a PC -
I don't know what is available for Mac.
In my experience, noise is a problem in all images from consumer cameras,
and in those shot at high sensitivities on pro cameras. But then quality
is a very subjective matter.
Scott Kelby's book is one we have discussed before. Some good material if
you can take the style. I find it only usable in very small doses!
