the noise in monochrome will show up with the old module, not with the new one. it's not in the original color image, so this is not a denoising algorithm, but one that avoids noise to pop up. the processing of a color filter is basically multiplying a noisy image with a noisy color filter made up from the same pixels (=> noise squared, if you're not careful).
better automatic denoising is in the works, until then a general piece of advice: - use the bilateral filter denoise module, set the rgb sliders to something proportional to your whitebalance coefficients, and radius to something like 7-10 (7.5 and rgb = 1.5 * wb coeff yielded the best results for a 5dm2 iso3200 iirc). you can also try to go a little lower with the green (as it has two pixels in the bayer pattern). -jo On Tue, Nov 20, 2012 at 5:58 AM, Matt Feifarek <[email protected]> wrote: > Hello there.
