hi, let me know how you go with the anscombe transform, that sounds important. in principle we should run it before black point subtraction, to be able to correctly extract the zero-mean values for black. the current transform wouldn't work with such data, however. cheers, jo On Thu, Feb 21, 20

Hi Johannes For now, I am working on denoise profile's anscombe transform, not one for rawdenoise (this may come later). Sorry if that was unclear. Basically, I'd like to have a variance closer to 1 for shadows. The basic idea I have is to use a linear approximation of the sqrt for shadows, while
