Hi Again, Excuse me, i sayed a big mistake :
After johannes add my merge, i have redone new preset (but it's wasn't merge as johannes sayed : >you sure these are better? the blue channel is still misbehaving a >little, and the curve fit for iso 100 seems to be off a little (see >iso100.pdf, how in the second page the green line doesn't really >follow the noisy green data). that said, iso 100 probably doesn't >matter too much for denoising ;) > >can you try pictures in daylight maybe? Few hours ago , when I have compiled a test version with both preset, i have use your preset & my new preset from my locat version (not merge, not the git current version ) I can see i real gain with your version (arround the same as my as my local version ) So for me, the git version is bad (my first version) my local version (but johannes think is not perfect) is (arround) equal to yours Regards Le lundi 17 d�cembre 2012 à 20:33 +0100, Emre Meydan a écrit : > Hi Roumano, > > I actually haven't tried your presets yet -- will do, and report > whether i see any difference or not.
