Noise is a treat in modern high pixel density cameras.
So, good denoise soft can make wonders in the kind and
you get some good results on the end. But, what is the
best one, have an idea here.
I like Topaz when it comes to print 9 x 13 or 13 x 18 prints
for an Album, but seen at full size, there is better ones,
Nik Define does good and Imagenomic Noiseware, but one that
really surprised me despite of reduced adjustments is the
Adobe Camera Raw native noise rework.
So look this shot a full size and reduced and make up your mind.
All pictures have been reworked with standard setting of each software.
You can see the full size shot in this gallery too,
but then reworked with personal settings in Topaz Denoise 5.01.
