I am comparing 100% view: 500px complained some days ago that a shot of mine was too noisy for their sales program. They say they want a clean image in 100% view. Now I am wondering how to give them that. Personally, I don't mind a bit of luminance noise. If you look at the large smoking chimneys, near that illuminated tower, you can see a kind of graininess/blotchiness in the clouds in 100% view. It's not there before denoising -- then the image is simply noisy, but the clouds are more uniformly cloudy. To me it looks like the non-local means filter uses a local means for the lightness of an area, and the borders of the filtered areas are showing as blotches. Or something like that. May be I am being fussy, but a little perfectionism doesn't hurt :-) Michael ------------------------------------------------------------------------------ New Year. New Location. New Benefits.
