Title: Luminance noise reduction in C1: increasing contrast?
Post by: bcf on August 05, 2014, 06:53:14 pm
The "Luminance" noise reduction slider is by default at 50, even for low ISO files. I noticed that, if I set it to 0, expecting the image to appear more sharpened, the image ended up less sharpened - or rather, upon further inspection, less contrasty (less local contrast).

Does C1 increase local contrast "under the hood" when the luminosity noise suppression is increased?

Anyway, I find that with luminosity noise reduction at 0 instead of 50, and the default sharpening settings, images look more natural: with luminosity noise reduction at 50, they are often exhibit too much local contrast to my taste.

Does anyone see the same thing (I use a D700)?

Did you lose interest in this question, Bernard?

Not at all Keith... I was away from my keyboard for a few days, and today the Phase One site appears to be down.

And it is still down.

No problem reaching them from the Netherlands... Maybe an issue with your ISP?

Cheers,

Could be. Though I'm not quite sure how to approach fixing it. I have tried 3 different browsers, another reboot, clearing browser history, cookies & cache, and trying to enter from the Phase One site directly. Nothing seems to work. And I have had no other issues with any other sites.

Now in. I erased the "/en" from the site, and in I went.

Yes, it works:

I have added a little someting to the thread, but nobody seems much interested. No more input by Phase One people, too bad.
