I previously used a Pentax PZ20 SLR and also a Canon G3 point-and-shoot. I have a couple of inexpensive lenses for the Pentax (FA-80 kit lens & a tamron 70-300). I would rather not have my selection dictated by these lenses, if I can find a better overall camera for the type of photography I have in mind.

Checked dpreviews.com where Canon seems to have lower noise but Nikon seems to have better color saturation. Which one of these would be easier to deal with (higher noise or lower color saturation) using software (Photoshop or Paintshop Pro etc.)?

Any thoughts or suggestions? Thanks..
