Opening
the Nikon *.NEF RAW file with Photoshop CS2 Adobe Camera Raw 3.1 or
Nikon Capture 4.3 results in different noise
and grain patterns, even with noise reduction
OFF in both programs. Photoshop CS3 results in
fine film-like grain that is more visible,
while Nikon Capture 4.3 produces a coarser
but smoother grain.
|
|
Photoshop CS2 with Camera Raw 3.1 removes noise well but introduces waves in uniform surfaces such as skies, common to many automated noise reduction methods. The Filter -> Noise -> Remove Noise command introduces more waves (see Image C).
Nikon Capture 4.3 removes noise without introducing waves but introduces some other artifacts instead.

When using the manual 123di noise removal method on
image A, the Photoshop CS film-like grain remains present
(but when looking at the RGB image the color noise
is removed). When removing the noise from image B,
the sky is free of noise and grain, resulting in a
very smooth sky. Image F is the best result, followed
by E. Of course E and F require more time.
