Just scene referred with 1.0 EV bump and three patches altered in the color lookup module…it actually worked fairly well…Did one small mask around her jeans but you could easily mask the sky to control this even better…I have taken using the module a lot lately…even some time selecting the white patch and just dropping the lightness or one of the first couple of grey patches can …I stress can really add a nice touch to highlights without much effort… ER6_4832.dng.xmp (8.7 KB)
Sky darkened easily …
Add a strait tone curve blended 10% subtract and it gets even deeper…
Todd,
The Color LUT is an interesting option, because although it works in LAB space and is deprecated, it does have a predictable impact on the image. Pick a section of sky, and increase/decrease lightness and/or saturation with easy-to-use sliders.
Is it possible to get the same effects in the color balance module with a parametric mask that picks out all pixels with a given hue?
My subjects are very different from yours and I also use a very different camera … however, like yourself I do find that my raw images appear to have more blue than I would like to see. My solution is to use a color-zone preset that I can easily apply. For me taste this provides a little less saturation and a little more lightness … but that is simply a personal preference. It is also easy also to adjust the preset for more severe cases.
I would say yes…so take the picker and select the sky …by default it will select the opposing hue so just add 180 t the number if below 180 or subtract 180 if the number is above 180 and then you can add saturation and adjust lightness…it might be targeted enough just trying the highlights or mids this way or you could mask…
I’m just looking now…I though originally you wanted to drop the blue but you wanted to lighten it…stupid me…just reverse my explanation but you can still use the Color Lut module for a nice easy upgrade to the sky…I don’t think its depreciated its just part of the display referred workflow and honestly again if you get the results you need just use it…you really don’t have to be so rigid with the modules…
I tried your suggestion of using the Color Balance Hue colour picker to pick a patch of sky then add 180 to get the opposing hue. I did this in the mid-tones, but this has an additional effect of pushing up the saturation and factor. Is this what you expect? Although it is easy to correct the sliders back to a reasonable image.
Also I have noticed that both techniques tend to push a lot of patches out of gamut. The picture still looks OK though.
It is, but I have the same question about pushing colours out-of-gamut.
I think Color Zones behaves less well regarding gamut, and I would be interested in the experts views on whether this matters if the sky still looks natural enough.
What is your setting for histogram profile and gamut limits…these can be deceptive and often the output profile has to map them to fit a Jpg file anyway…https://discuss.pixls.us/t/color-spaces-nightmares-gamut-clipping-wtf/22085...As for CB it should not change the level (level has its own picker) only the hue and saturation . I only use them for color casts or to enhance so I rarely change the hue it picks…I just use the 180 degrees if trying to enhance and as is if correcting a cast and then I adjust as needed with the saturation…I do the same with color calibration. I always switch to custom to display the hue chroma sliders and I adjust the chroma to suit my taste…
How are you assessing out of gamut??
These options will matter. I usually just use luminance and judge Saturation by eye.
Also I use AP’s recommendation to set my histogram profile to linear rec2020 ie my working profile…if I keep the histogram in good shape while editing then I have never violated the data and the output profile will remap …I use perceptual but there are instances where some might choose relative…If you set you histogram profile to sRGB you will show gamut and clipping all the time
This is how i have it set up …if I want to reference the sRGB histogram I turn on softproofing which I have set to that …other profiles are the profiles for each of my monitors…
In fact my journey through darktable 3.4 started with a run through all the new options. For the options I didnt know much about, I just followed online guides that suggested some default choices. As I have processed some 2000 photos, read up on things, and asked questions, I can now go back and make some more informed choices - in this case regarding profiles.
Right now I have loaded up the 3.5 daily snapshot and started using the new Color Balance RGB module. It looks like a super tool, and I have definitely improved some recent photos by trial and error, but I would still like to understand more about the ways to use it.
This thread has become a bit lengthy so once my thoughts are clear I will start another thread to discuss a particular photo I have been working on.
