Hi!
I’m looking to move away from under the Adobe umbrella to Rawtherapee. It’s great! There are of course some growing pains.
Part of what I shoot is infrared images with unmodified camera and Hoya R72 filter. I know how to get the whitebalance and channel mixer working, but I do have to boost the exposure by 2-3 stops usually, which has this blotchy noise across the entire frame.
My problem is more so, do you call it noise or is it artifact of demosaic method? I generally use RCD+VNG4 demosaic method. I’ve tried noise reduction with aggressive profile, which sort of works but only to an extent. I can share samples below:
I tried LMMSE demosaic as well but it honestly looks worse with that. I’m happy to hear any suggestions. Thanks!
