I think this is a great idea. We can share RawTherpee profiles, tweak them a bit, & re-share them.
I've been toying around with RawTherapee for a while now. The main reason that I use it is that I can run the program with the exact same settings on both Windows & Debian. If you dual boot a Windows & Linux system, this program saves a lot of time & learning curves.
I have a few profiles for the K-50 that I have created. Mainly jpeg processing out of DNG files for different ISOs, but I'm still tweaking them. The profile that I have been concentrating on the most is a profile for ISO 1600 to ISO 3200 that gives me the cleanest results with the most amount of fine detail & the least amount of chromatic noise possible. The high ISO color splotching noise. I also have one that's a bit more aggressive for ISO 6400, but I'm still tweaking that one. The high ISO photos do have some grain, but it's a very fine & pleasant looking grain. When I compare a higher ISO OOC jpegs to the RawTherapee jpegs, the difference in processing is quite amazing. The high ISO OOC jpegs are quite "splotchy" while the RawTherapee jpegs have more detail. I haven't tweaked the colors much. They're pretty close to what the "Natural" jpeg setting gives me. I'll have to get around to the colors later.
I have Photoshop CS4 on my Windows side & Photoshop ACR can't produce a high ISO jpeg out of the DNG like I can get out of RawTherapee. The high ISO jpegs that I get out of ACR do look better than the high ISO OOC jpegs, but not as detailed as the RawTherapeed jpegs.
The lower ISO OOC jpegs & RawTherapee jpegs (ISO 100 to 800) are pretty close in terms of image quality, but the RawTherapee jpegs still beat the OOC jpegs.
I'll post up that high ISO profile (1600 to 3200) when I get home. If anywone else is up for this, we could have something pretty awesome here. K-30 owners can use the same profiles & contribute as well!
