Say I want to make red tones more intense or light but just inside a selection, selection made with radial filter for example. Can I do that in lightroom? If I have to go over to PS for this task, what would be the quickest way? If it's NOT possible inside LR I very much like to see this feature added!
You can't use the HSL sliders but you can use the Color Range Mask in local adjustments; 1 Use one of the Local Selection tools to Select and area that includes the red you want to change2 Use the Range Mask/Color to select just the range of color you want.3 Change the local Hue, Saturation and Exposue sliders. Exposure is the substitute for L in HSL Check Youtube for a video on using the Color Range Mask in Lightroom Classic for more info.
There is a Saturation local slider, there is an Exposure local slider, and there is a Hue local slider (in the last few versions of LrC). So, select the area of interest, then adjust the saturation, exposure and hue as needed.
