Does "Auto fine tune" degradate image quality?
Posted: Tue Nov 18, 2014 2:59 pm
Hi NI Team,
after "upgrading" my camera from 10 to 20MP I made the observation that "Auto Fine Tune" strongly degradates the result of the denoised image.
I want to ask if "Auto Fine Tune" does work properly in my case using a EOS 70D.
I prepared noise profiles from the calibration target (100% quality for all isos).
I compared this:
1.: Opening Image/auto match/process/ - perfect result as expected!
2.: Opening Image/auto match/auto fine tune/ process/ - almost unusable (even if the quality indicator is greater than 75%):
lumiance remains completely or become even more apparent due to enabled sharpening.
chrominance: green/red/blue smarties remain in all dark area.
I can truly live with the results of disabled auto fine tune.
But when I want to use smart profiling I cannot disable auto fine tune as stated in the manual:
"Use the Profile > Smart Profile menu item (or press the F5 key).
Smart Profile uses both Auto Profile and Auto Match (with Auto Fine-Tune) to prepare two candidate profiles and then selects the better of two profiles. "
So I have two questions to you:
Is there a way to use smart profile with disabled "auto fine tune"?
Does "Auto fine tune" work properly?
many thanks for your help in advanced
