The new Coolpix
5000's ISO 100 already provides relatively clean images,
with minimal amounts of noise when shot in normal light conditions.
However, when shooting in low light, there is a possibility
that ISO 100 images could have
a noticeable amount of noise in the shadows. In addition,
there is visible chroma noise at this sensitivity.
This smart action will ONLY reduce
noise when necessary. Therefore, you can safely run
iso100-ISOR5000
with all your ISO 100 images, and not have to worry about
loosing precious detail.
It also works in Photoshop
batch mode, which is a great timesaver for professionals
who want to clean up a large quantity of pictures all at once.
