Hello,
I still use LightRoom for removing spot but I am very happy of RawTherapee vs Iridient for original color DNG files on the K-1 (II)... No spot-removal needed for these ones. "Fantasy" colors process...
Best regards.

Two steps forward, one step back. Or maybe two steps back and one forward. I took a 150-odd pictures at my kids' soccer game Saturday morning. Got home, used Rapid Photo Downloader in Linux to get them off the SD card. Fired up RawTherapee and started editing. It went reasonably well, but fairly slow and not completely comfortable with the flow and the results. It became obvious that my pp3 files I'd been modifying aren't consistent - I'd have different levels of contrast, saturation, vibrance, etc. for ISO 400 and ISO 800 and ISO 1600. Both teams had a lot of red in the uniform, and I'm having trouble with that being too saturated. In Lightroom I just go to the color panel and turn down red saturation and I'm done. I haven't quite figured that out in RT.

So after a bit I booted Win 7, went to Lightroom, and inside of an hour I had all of them edited mostly to my liking. Felt a little like cheating, but it would have been hours trying to do the same thing in RT. I need to go back and make a better, more consistent set of pp3 files and work to get the results that are (for me, for now) easier to achieve in Lightroom.

First picture is Lightroom, second is Raw Therapee.

Recently I've been working with any studying the wavelets tabs more, and it has opened up a world of new opportunities.

I shoot a lot of film alongside my digital. My workflow has been film scans would go into Darktable and digital into Rawtherapee. But I found I can open the first shot from a roll of film in Rawtherapee, make a few adjustments in the wavelets tab, copy to clipboard and apply to each shot. It has become a time saver and gives me so much control over every aspect of the image.

I think the wavelets is the most powerful hidden tool of Rawtherapee.

I have a question about using Adobe lens profiles. Somehow I got this to work, mostly, before. But now I can't remember how to point RawTherapee to the directory(s) that I have Adobe lens profiles in. Under user/config/RawTherapee/profiles I have a couple directories of Pentax lens profiles but, I don't think that's what it's using. When I go to the Profiled Lens Correction area under transform I have a ton of options, not just Pentax but I think all of the stuff Adobe supports. But weirdly, it's like it's an older version because the 55-300 PLM isn't there (the file is under the profiles directory referenced earlier).

Anyway... how do you tell RawTherapee where to look?

Apologies for skipping ahead from page 8 where I am at the moment.

The OP and several messages since then all direct the reader to the OP to obtain relevant Pentax dcp files. None of the colorful headings that I thought might be the link are presently dcp file links. Have these been withdrawn, my observation skills become defunct, or is the intended link broken?

My first goal is find out whether there are profiles suitable for the 645Z. I was able to install RT 4.0.12.0 from my Mint build's Software Manager so I have something to experiment with, but it won't load a 645Z PEF file for testing. It shows the content image, but I suspect that there is a thumbnail jpeg hidden in there somewhere that it is using.

Also of note for the OP, the Raw Therapee site's Downloads page shows no Linux files. There is a build-your-own distribution page elsewhere at the site for those who love compilation. It may be that the OP needs some retuning after all this time.

Edit: The appimage file is apparently the all purpose Linux file. I will try it. My dcp question is still open.
Edit2: Installation worked except that generating the links failed, hanging the process. Otherwise, manual starting works, export from 60 MB PEF to 307 MB TIFF works. The program seems to have access to all of the EXIF file. I have no idea what dcp it is actually using. Actual editing will require significant reading. The rest is only detail. My dcp question is still open.

Thanks

Same here. Linux user. I am missing something? I read a long time and was unable to determine where to obtain the dcp files that are repeatedly referred to. Other than that, I am greatly enjoying the program and greatly appreciate this thread.

To bring my earlier message up to date, I have now caught up with this thread. I haven't installed any profiles yet, but have downloaded three sets to look deeper into. I expect I will be upgrading Mint soon, so maybe the start-up links will be built automatically. This is not a big deal because I can always make my own, stealing an image from RT's data in user/shared if necessary.

Anyway, for jbondo, the links to various profile files that were long ago provided in this thread have been deleted. But going back in recent messages to 1 Jun 2018 will reveal links to recent relevant files that The Squirrel Mafia (TSM) has developed and so graciously provided.

I have observed that the dcp profiles in user/share/rawtherapee do not include the 645Z. Yet the operation of importing a 645Z PEF file and exporting a TIF file seems to work correctly. Perhaps the key to success is that TSM's white balance profile taken from the embedded jpeg is allowing what my earlier testing with Darktable failed to achieve.

In any case, thanks to the RT developers and TSM for all the work making this the first of several PP programs I have tried that has successfully functioned under Linux Mint and done the file conversion. I look forward to becoming familiar with its legion of other capabilities.

You can create your own DCP profiles but RT comes with lots of them for popular camera, don't know for the 645Z. However you'll have to use RT 5.4, which require Gtk3.18 minimum, which might not be the case for old Mint distribution.

The OP only provide PP3 processing profiles, IIRC (can't check the whole thread now)

I am running RT 5.4 under Mint 17.3 on this particular desktop PC. The dcp camera listing does not include the 645Z. Nonetheless, at the moment, I am happy to have a means to convert PEF to TIF. I believe once I learn more, RT can do other modest PP functions I may need. In any case, I plan to upgrade my various PCs to Mint 19 when I get time. I am curious whether that will improve Darktable functionality also.

As to generating my own dcp profiles, I haven't yet fully grasped what images are needed even for others to do so, much less the dcp file structure and content. Perhaps 645Z profiles are out there somewhere; I have only just started learning this aspect of digital camera operation.

Hey folks! Sorry for not getting back sooner. I can no longer edit the first post of this thread. It's too old.

I took down the DCP files a while ago, since RawTherapee can do a pretty good job of figuring out the input profile from whatever RAW file you use. I do have the PP3 files set to Auto-matched camera profile, (cameraICC) in the PP3 file, but it will default to Camera standard if it can't find the correct DCP.

You can make your own DCP files in RawTherapee, although I haven't played with that yet, or you can use the DNG Profile Editor from Adobe for either Windows or Mac. That or you can copy the DCP profiles from Lightoom if you have it.

I'll probably end up having this thread locked & starting a more simplified thread later on to make it easier for the new folks that are just trying this software out. The PP3 files do just about everything for you already. As soon as version 5.5 of RawTherapee comes out, I'll have a new set of PP3 files for it.

I have a question about using Adobe lens profiles. Somehow I got this to work, mostly, before. But now I can't remember how to point RawTherapee to the directory(s) that I have Adobe lens profiles in.

I haven't been using RawTherapee on Linux for a while now, but you can try placing them into usr/share/rawtherapee/share/lensfun to see if they show up. You'll need to go into that directory in root mode to copy files into it. It won't let you copy into it as a standard user. You'd have to use gksudo nautilus if using Ubunutu or something like that in the command line to get root access to it. It all depends on your file explorer (nautilus, dolphin, caja, etc.).

Thanks. Are you suggesting above that the subfolder .../share/lensfun is to be created under .../rawtherapee, not just populated with lens data? In my RT 5.4 appimage build no "lensfun" subfolder exists within the usr/share/rawtherapee folder.

Hmmm..... It might be different in Linux then.

C:\Program Files\RawTherapee\5.4-923-g07dafc67a\share\lensfun

^ That's the typical Windows directory where you would find all the .xml files for the Profile Lens Correction section in RawTherapee. You can try creating a folder to see if it works.

I see no .xml files in the usr/shared area for RT. I haven't found any other locations used by RT other than where I put the appimage executable. Maybe the .xml data is buried in the executable.

Thanks for the response. I just PM'd heckflosse because I have continued to try to unravel where RT is looking for lcp files with no success. The 55-300 still doesn't appear in the dropdown even though it's in my old Lightroom directories and in user/config/RawTherapee/LensProfiles.

Thanks for the clue! (Now I have at least one.) In Mint I have a folder "~/.config/RawTherapee/profiles" that is presently empty but might be where my appimage build expects user supplied files of certain types to be placed. TBD in the fullness of time.
