Thank you, Bruce. A number of facts were added to my scattered knowledge about this tool.

Interesting. Love the videos where you try to figure out new tools and understand how they work. It's like watching e Chef cooking and then eating it instead of just eating - if you know what I mean. Thanks

Haha. Thanks. The trick is to get the balance right in the editing so you are not forced to watch me trying to figure stuff out for too long!😃

Yes, this version clears things out in a much better way. Thanks

Videos 136 & 137 are great for several reason besides well done! 1st I finally update darktable to 4.6 after much hesitation. 2nd Learned how helpful these models are to what I do and 3rd I can now make better B&W conversions with deeper tonality! Thank you for these great videos!

No problem.

Don't worry about the difficulty Bruce. I know the LR devs are likewise having difficulty trying to copy Darkroom and anticipate future Darkroom features.😂 This should ensure Darkroom's power, purity and feature advantage over LR increases ever more.🎉

That would be a great world to live in! :)

Purity is equivalent to Pigment in visual art nature and colour mixing, it is irrelevant of light/dark of the pigment depending on the chemical makeup, transmission/reflection based on light and shadow! Pigment is where all painting starts from and then you add the chemicals to filter/spread/tint from with oils, water, mediums and black or white or other pigments

Right. Not having painted, that is all new to me!

@@audio2u most wouldn't know unless they had, it's good for understanding colour. Photography, Fine Art and Science all come together. :O) Have a great week

Thanks for the video, great work. Question: is the RGB primaries module when used with a parametric mask equivalent to the Lookup table module? I have a very old computer that refused to run V: 4.6

@audio2u 9 ай бұрын

Good question... I'm really not sure. I have never used the look up table module, so I'm a little bit in the dark on that one!

Would a module like this be good for astrophotography ? I'm looking for a work to post-process astro. Thanks and God bless.🙏📷

@audio2u 7 ай бұрын

I don't see why you couldn't use this module for that, but then, astro isn't my main genre either! The modules that come to mind (for me) if I was thinking of post-processing astro shots would be: * Astro denoise (or maybe profiled denoise) * Colour Calibration (for white balance) * Colour Balance RGB (Brilliance grading... drop shadows, boost mids, boost highlights) * Colour Balance RGB (boost chroma and satuation in the midtones) * FilmicRGB or Sigmoid (for tonemapping)

I think your concept of purity on a HSV colorspace would work if you imagine it as a sphere with black and white at the poles (and not as a cone with black at the tip, as it is usually represented, or as a cilinder, as I guess you imagined it when recording the video). Then max. saturation (distance between surface and central unsaturated axis) would happen at the equator, i.e., "when not displaced towards black or white" = at max. purity. Does this make sense?

@audio2u 10 ай бұрын

Yes, that makes sense! Thanks!

Hi Bruce. First i want to say a big thank you for this very detailed videos about darktable. Its a very complicated but powerful program. Im watching your videos now for a few weeks to get into it. One thing i havent found out about darktable which is how to desaturate single colours on its own. I tried to make a dark moody photo with only a few single colours in it. Ive seen Lightroom videos and there are simple sliders for RGB Magenta and so on but i cant figure out how to do that in my photos. Is there a simple solution for it? If you want to see what exactly i mean. There is a yt video of "Mark McGee Photos" and the video is called "How to Edit DARK MOODY TONES in Lightroom (Full Tutorial)" I want to copy that to learn more but i cant get to this result. Maybe you have the solution for me :) Thank you in advance :)

Thanks for the kind words and support. What darktable offers in masking is amazing. I would highly recommend you watch my series on masks (ep 113-117 from memory). In particular, pay attention to parametric masks, where you can limit a selection range based on hue. That should get you started!

@BenderRodriguezBender 10 ай бұрын

ah, ok thank you. i hoped there is a simpler way to deal with single colours :) but yes, masks should do the job too @@audio2u

Have to say I am having a bit of trouble knowing when to use this tool.

@audio2u 5 ай бұрын

Yeah, same here. I don't imagine myself using it a whole lot.

If you have ever used a Channel Mixer in PS or similar program, this works in a similar way. I also think Lr has a Colour Calibration panel that does similar things. If you never really use those tools, you might not ever use this one either.
