My first stop is to enable the profiled-denoise; I find this does quite a good job if I have not had to 'pull' the data heavily. As a second step, if needed, I then use a very small value of raw-denoise. I am finding that I only need to use the local-means and bilateral-filter if my initial exp

Hi, if I need to denoise my photos, I use wavelet denoise in HSV color blending mode for the color noise, and if also I want to get rid of luminance noise, I use the non-local means denoise in HSV luminance blending mode. Usually this works well. In evening shots, the sky sometimes gets uneven/bl

Have you seen the answer from Kofa? Just load the image in GIMP and use the color picker. You will see: Its your calibration. To be more precise: Its the ColorHug. The ColorHug is a nice idea (in fact, i own one, too) but not mature yet. Additionally, the device can not be 100% precise by design,

Thank you, Oliver. I recalibrated my monitor (ColorHug + dispcalGUI). I still see a slight brownish tint on the walls. I changed the correction (in the color correction module): now I only lowered the white dot. The resulting image: https://dl.dropboxusercontent.com/u/2171814/paris-por-francisco-c

Francisco, On my screen, the slight bluish tint is visible as reported by Pascal. Also, I opened them in the Gimp and checked RGB values. The 'unadjusted' BW has R = G = B, the 'adjusted' v2 version always has B > R. Kofa --
