I’ve taken another community member’s advice to set the Luminance default at 12. This has been good for low-ISO micro four thirds images, provided there isn’t a lot of exposure lifting to recover shadow detail.[/quote]
That’s something which i like to test with you.
if you bumb up the level to say 50% luminance how much difference they have comparing to the 12% versions? or in steps 20% 25% 30% 40% 50%. where start the change?
One thing come to mind, could the luminance slider be a reversed gray chart mask? (0-255.)
10% : only the real dark pieces are masked and treated. 0-10% of 255
20% : the parts with rgb-level 0-20% of 255
40% the parts from 0-40% of 255. (102)
i checked but the levels and numbers don’t add up.
my moon shot has a 109 rgb and it denoises ad 16%. the difference is clear at 16% between hq and prime.
so it much be a sample percentage. creating a moving threshold of which level of signal is called “noise” combined with image scanning algorithm to find the common “signal” which can be called “noise” like dubbing a frequency out of sound to enhance the human voice in loud suroundings.
See waves have a certain flow and frequency of sound turn that down with that flow ritm and the wavesounds are suppressed.
where grain starts to be converted to artefacs and smutching blotches or the “plastic look” is appearing that’s the place to stop adding denoiselevel.
or for artstistic purposes a filmpack kind of neat equal grain.
So the major question remains: why on hq and prime is 40(%) the deafult?
moon shot proves that HQ 16% is much less effective as 16% PRIME. so why are they the same default level?
