One thing to note Andy and many people have no idea is that 0 to 1 in Jz is not full-scale. You highlights can often be at 2 3 5 or higher. You need to use the picker and sample the highlights and note the value. Then use the mask boost slider to make sure it bumps Jz higher allowing you to select the full range of the image... Many people have complained about masking using Jz and it not working well with highlights....this is why
One thing I'd be interested in is a comparison between the saturation mask technique and setting up filmic so that it desaturates shadows and highlights. Or how they affect each other when used together. One obvious difference is that filmic happens as the last thing before leaving scene referred, so the color balance module can't take that into account... but I'm not sure what the implications are.
Hi Tom, as I replied to Michal, I try and keep things simple and familiar for the likes of Photoshop users. And making a mask is more "recognisable" than setting up a module intance, and it's more versatile. Am always open to suggestions on how to do things though Tom, as I never profess to being a DT expert!
Many thanks for your video. It very informative. But let me ask two questions: 1) Isn't filmic (and sigmoid as well) supposed to do roughly the same automatically, i.e., lower the saturation in highlights and shadows and set it to zero in white/black (where white and black is defined by these modules)? 2) (Sorry, this is an offtopic.) Do you use darktable on macOS Sequoia? Is opencl still working there? I'm about to upgrade but I worry about Apple dropping the support. Based on my experience with Linux, using darktable on CPU is miserable compared to GPU.
Hi Michal, cheers for the feedback 👍 Filmic - yes, but it's yet more "stuff" to learn for someone not familiar with the inner workings of DT. I am currently running DT in the latest version of Sonoma - as always, I resist upgrading my OS until I know that it doesn't effect Photoshop, Lightroom Classic etc and that FOSS dev builds are out there that can cope with it too. DT builds are usually fine with an OS change, but I still run Raw Therapee, which sometimes lags behind a bit, and I'm currently playing with ART, which I'm loving for its simplicity. My attitude to upgrading is "if it ain't broke, don't be in a rush to fix it"! I'll be spending the next few days checking what works and what perhaps does not; always let other folk find the bugs!
If anyone has an answer I had a problem. I have a new laptop and I was working with Darktable and it suddenly crashed, before it did there was a white balance error message. After I tried to restart the program would not load. I actually had to uninstall and reinstall to get it to work. So far it is still working. Has anyone else had this problem?
Hi Gary, this is a question best asked and answered on the Darktable forum at pixels.us. Very occasionally, I have a crash in FOSS while processing. Fastest way I have found around the problem is to use your file explorer and go to the image that just caused the crash. Next to the raw file you'll see the xmp written by darktable - delete it. If you don't delete it, Darktable will try to reapply it and instantly crash again; sometimes it won't appear to even start. ART is very good at doing this too! It's as if the crash is written into the xmp/arp.
@@AndyAstbury windows 11 home edition. So far this problem has not re-occurred. I did delete the image file from Darktable and is working great so far. I really appreciate your input on this! I think I accidentally generated an internal command conflict and this caused the problem. Time will tell.
Let me know if you get any other problems Gary. If you want anything specific covered in DT, just let me know - perhaps drop me a direct email tuition@wildlifeinpixels.net
Interesting. The Darktable Landscapes channel also did a recent video on processing an image with only color balance RGB (mostly -- He also used crop and some sharpening). cbrgb is a powerful tool, no doubt.
Boris did a video years ago when the new version of CB came out...he did about 5 edits using only RGB CB only to show the power of it . Good to revisit things and put a different spin from time to time
Already loved the Photoshop saturation masks, this one is also brilliant !
Thanks Andy
You're very welcome!
Well done Andy, that's gold, thank you very much.
Glad you enjoyed it
Excellent! Thank you!

Question were you doing all these edits in RGB as a second instance?

@ thank you I will try that!
Let me know how you get on Gary. What operating system are you using?

Always be wary of demos online where they rarely show you the image adjustments at 100% magnification!
