Denoising with hot pixels

Pushing the hot pixels module to its maximum in one of my noisy and dark picture worked pretty well, details are well preserved. Though, note the change in the colors, from magenta to green. Maybe this could be compensated for in the denoise module with the bias correction, but I think I prefer the greenish tone compared to the magenta one.

Just sharing this “discovery” with you if you want to give it a try :smiley:

Yeah, I’ve found this out also. The hot pixels module tends to get rid of the bright impulse noise (white speckles) in very noisy areas. It’s not as good as Rawtherapee’s Impulse Noise module as it doesn’t handle dark impulse noise, but it’s not bad either.
