I think I have replied only to Gonçalo and not the entire list. Sorry if the message is repeated, but I do not know exactly how this is used.
I have noticed that in some of my photos profiled noise reduction is applied much stronger than before (even in low isos), loosing details. I mentioned this to the developers, but they have told me that there was no change in the code of profiled noise reduction. So perhaps changes in demosaicing code?. I don't know, it is somewhat confusing to me because apparently in some photos I lose more details than others. First I thought it could be related to having the OpenCL enabled, but I'm not sure and I can not find patterns about when this issue is more noticeable. 2015-09-04 5:17 GMT-03:00 Gonçalo Marrafa <[email protected]>: > Hi list. > > Regarding this matter, from the discussion that took place, i could not > conclude if there is in fact a problem with the denoise(profiled) module or > is just poor use by my part. > > Any developments on the issue? > > Thanks in advance. > > > Gonçalo Marrafa > > ---------- Forwarded message ---------- > From: Gonçalo Marrafa <[email protected]> > Date: 14 August 2015 at 23:44 > Subject: Something wrong with denoise(profiled)? > To: "[email protected]" < > [email protected]> > > > Hi all. > > I'm having some problems with the denoise(profiled) modules.
