UPDATE!
I have a new build on my Google Drive with some revamped PP3 files included. The included "ISO" PP3 files have the most basic noise reduction. They will get rid of most of the color noise possible, but still retain most color. The "Aggressive" ones eliminate almost all color noise, but it comes with a cost of losing a tiny bit of color. Neither of those "ISO" PP3 files do much to the luminance (grain) noise. This keeps most of the fine detail intact as the ISO gets higher.
If you don't want any luminance noise in your pictures, then go to the
TSM - PP3 Optional folder, you will see 3 files with noise reduction settings. Use these after you apply an "ISO" PP3 file.
Noise Reduction - 1 Wavelets Fine Grain
^ This one refines the luminance noise. The image looks a bit smoother, but still has luminance noise.
Noise Reduction - 2 Smooth
^ This one almost wipes out the luminance noise, at the cost of smudging fine detail a bit. This one reduces the image file size by quite a bit.
Noise Reduction - 3 Wavelets Fine Grain & Smooth
^ This is the most aggressive one. You lose quite a bit of fine detail.
Please note that I have 2 builds in there.
One of these has all the "ISO" PP3 files set to the sRGB color space. This is close to what you'll get out of DxO, PDCU5, & your camera.
The other one has all the "ISO" PP3 files set to ProPhoto that has a wider color gamut. I personally prefer the sRGB color space, but I know that a lot of folks here love the ProPhoto color space.
The only modification that I do to the RawTherapee build is changing the default
Film-like tone curve to a
Standard tone curve. I do this by changing
FILMLIKE to
STD in the
improccoordinator.cc &
simpleprocess.cc files before compiling.
For the rest of you that download a build from the RawTherapee site or compile your own builds, I'm attaching 2 sets of PP3 files. One with the sRGB color space & the other with the ProPhoto color space. These are the same ones included in my builds. Keep in mind that the website builds use the
Film-like tone curve & unless you change those files specified above in your build, you're also using the
Film-like tone curve. Have fun!
