UPDATE!
I've uploaded some new PP3 files for both Windows & now Linux.
Doing PP3 files for Linux is tricky due to permissions, file locations, & so forth & so on. The ones that I have uploaded for Linux work perfectly fine on my
Fedora 33 distro the way I installed them into the
/usr/share/rawtherapee/profiles folder, the
Pentax DCP folder in to the
/usr/share/ folder, & the
dynamicprofile.cfg into the
/.config/rawtherapee folder. Your results may vary. Keep in mind that you kind of have to know what you're doing or else you could screw up your RawThrerapee installation & even your Linux installation if you're not careful. With that said, hopefully they help a few Linux users out there.
There are a few changes mainly to the color PP3 files & a new, but still experimental,
TSM Natural PP3 file that takes the Natural.dcp file with a few exposure tweaks that ends up giving you an image that has similar contrast & brightness when using the Bright.dcp file, but without the color over saturation. You'll have to try it out to see if you like it.
There's a Windows 64bit build on my
Google Drive as well. Have fun!
