then applying complex algorithms to remove the noise without destroy-
ing too much image detail (Figures 5.9 and 5.10).
Photoshop CS3 has its own built-in noise reduction program, acces-
sible from the Filter menu (Filter > Noise > Reduce Noise). It is not as
complete or, in my view, as effective as specialized noise-reduction
programs, but it is better than nothing. Try experimenting with the
settings.
One of the problems with all noise-reduction software is that even
when you exercise great care, it can still remove some useful image
detail when it removes noise, leaving the image looking too smooth
and “plastic.” To avoid this, experiment by using different amounts of
noise reduction. Use the “fade” command in Photoshop to reduce the
amount of fi ltration after the event if necessary. Use only the minimum
amount of noise reduction necessary to remove the worst of the
noise.
