[Leica] comparison of 4 noise reduction programs

[Don Dory]

Douglas, sometimes you have to go out in the dark.   I support a non-
profit and some events are in a darkened presentation room.   Also,  there
are times you need f8 for dof and the light is low.   Knowing there are
tools that will reduce noise is important: as well,  knowing the tools
available in an Adobe product are competitive is nice to know.
