Lightroom: More Flexible HSL Control

  • Updated 6 years ago
Sometimes I want to change the hue/saturation/luminance of a colour but none of the eight predefined colour sliders matches the colour in the image I want to address.

For instance, I often see a purpleish colour but the "Purple" slider has no effect at all.

It would be great if one could tweak the base colour of a slider to adjust it so that it matches a particular colour in the image.

The icing on the cake would be a "range control" with which one could control how narrowly/widely the match to existing colours is made.

An analogy from audio technology are parametric equalisers which also allow to choose the base frequency of a filter and how narrowly/widely it is applied to the input signal.

Ultimately, I'd like to be able to specify mask parameters with base colors, range control, and luminosity... then tie HSL, NR, or whatever other adjustments there are to the mask, but in lieu of that, more control of HSL proper would be welcome.

Instead of dragging sliders, have you tried using the targeted adjustment tool ?

Yes. The TAT just presents another way of (selecting and) moving the sliders, so I wasn't surprised that it didn't make a difference.

I'd suggest playing with it a lot more, as it does sample where it's being moved and should (and in my experience does) allow all the control one needs.

Sometimes one wants to bring out the green in something that's being considered yellow-orange by the HSL tool, no matter where one clicks with the TAT tool.

"The TAT just presents another way of (selecting and) moving the sliders"

This is true, but it moves multiple sliders at once and ends up "mixing colors" to adjust the selected color. I find this tool works extremely well and I've never had the problem that Rob mentions where it doesn't actually adjust the color in question.

Sean, yes, the TAT often moves several sliders at once but it doesn't move any sliders that don't exist. I have a suspicion that the eight sliders don't cover all of the colour space.

I think a super masking technology with all adjustments localizable would handle this case perfectly, and a zillion others... But if that's too much to ask for in Lr4, then some other way to better target and adjust photo colors in Lr would be appreciated. At present, if HSL tool doesn't cut it, its darn hard to do satisfactorily in Lightroom.

This orchid stem toward the lower left has purple and green in it, but is considered equal parts yellow and orange, thus there is no way to bring out the green or purple.

Thanks, Rob. I haven't tried your particular image but I trust that what you write is correct since I have experienced the same with other images myself. Hence my FR.

Yeah - The HSL tool works "perfectly" with a pure color (1 of 8) *or* a blend of two adjacent colors, e.g. red, or a reddish magenta; blue, or a blue-ish purple... If you think about it yellow and orange are between purple and green, going the long way around anyway. TAT tool either adjusts one slider, or two adjacent sliders, and it uses a multi-pixel sampling to decide, so when it finds purple and green, whats a poor HSL tool to do...? - go for the purple?, go for the green?, or something in between? Answer: something in between that's neither, in this case. But even when its working perfectly and adjusting the color you want - say using the TAT tool, adjusting a yellowish orange still changes the color of all the yellowish greens too - so it would be nice if the range could be narrowed, in case you wanted to adjust yellow-oranges without changing yellow-greens too.

What I really miss is the possibility to select the color not only by its hue but by its saturation and brightness also. This would allow for affecting for example only the dark and vivid green tones and leave the other greens where they are.
If the TAT would be able to do this it really was an enhancement over the sliders. (hmm, I guess we would end up with having it look and behave like the U-Points in NIK software then)

Amen, and hallelujah.

I submitted a FR/Idea for luminance constraint of HSL (with mention of saturation too) but so far it has gotten a cool reception - please vote for it. I agree if general u-point type masking were supported this would be moot, but if not, then constraining the HSL itself by saturation & brightness would be a big help to me too.

The one feature that I feel Apple Aperture really beats Lightroom at is HSL/Colors. I think the ability to use the eye dropper to select a precise color and then adjust the HSL of the chosen color certainly beats just being able to change the given colors in Lightroom. I've found that the Aperture allows for more dramatic adjustments of the colors before it starts to look unattractive. Also, Aperture allows one to brush these adjustments into specific parts of the image. If this was an option for masks in Lightroom, this would be very useful. It would be great to see these features added in the future!

DNG Profile Editor (DPE) allows one to adjust color (hue, saturation, and luminance) based on hue and saturation (not luminance), as narrowly or broadly as you want. Most people use DPE for reusable profiles only, but I also use it for onezies sometimes. Consider:

HSL should definitely have the option of a "brushed in" capability ... sure you could accomplish some tasks with brushed in White Balance ... but ... the option to invoke HSL ... would offer much more control ... I agree that Aperture offers much more flexibility in this respect and is a concrete example of what is possible ...

I strongly disagree that using the DNG Profile Editor in this fashion as the result is a global function. You can't use a Camera Calibration Profile to effectively isolate only a portion of the image as it's settings are indeed global. Lightroom already offers adequate options for global adjustments.

Only a brushed in or selection capability could make this option shine to it's fullest ...
