    When should noise correction be applied to a digital photograph - or does it
    matter?

    Noise correction/reduction will highly degrade original photo. When
    possible, it's best to limit ISO setting to minimal, and thus reduce source
    noise to minimal. If shooting at very low light, and ISO is forced to be
    high, sometimes helps reducing noise, but only if applying very gently. In
    any case, if you intend to play with noise reduction, be sure to keep
    original photo intact, so you can always go back if you screw it. Some of
    the programs are Helicon noise filter, or Neat Image etc...

    If applied to the Raw data, it'll increase the chance of posterization
    upon further processing. It is IMO best applied after basic gamma
    adjustment, and before further processing.

    Some say before sharpening, as if it is done after you can sharpen the noise
    and make it harder to remove...

    Working with Photoshop CS and Raw files, noise is always the first thing
    that you compensate for before you do any other adjustments. Seems to give
    the best results doing it this way. Also, sharpening is always done last,
    just before you are ready to save the image.
    Cheers

    Hi...

    Just double checking... even before gamma is pulled up?

    Yeah, noise is first as any other adjustments will affect noise but not vice
    versa
