In previous weeks we have looked at manipulating the light of an image with basic adjustments as well as with curve adjustments. We also have seen that with the curve adjustment you can stylize a picture by manipulating the colours at different brightness levels, for example making highlights more yellow or shadows greener. The HSL (Hue Saturation Luminance) Color Panel allows you to manipulate the look and feel of the overall colours in the image.
If you wish to watch the companion video for this post you can so here.
The HSL Colour panel can be equated to the hue and saturation in Photoshop. The HSL/Color Panel is separated into three parts; HSL, Color and B&W (Black and White) in Lightroom, In Adobe Camera Raw there is only HSL and Greyscale. Greyscale and Black and White we will look at in a later post. For all adjustments you are given the eight colours to adjust, that covers the whole colour wheel.
Clicking HSL gives four options; Hue, Saturation, Luminance and All. By clicking all, the entire panel is extended with Hue, Saturation and Luminance becoming a vertical list instead of sub panels.
Adobe Camera Raw has the HSL Panel but does not have a Color panel. In Lightroom Clicking on Colour gives you individual colour options each with a hue saturation and luminance slider. It also gives you the option to see all the colours in one long list, if you click all.
HSL also has a targeted adjustment tool that allows you to click an area on the image and like with curves, move it up and down to increase or decrease the adjustment.
Hue adjusts the global tonal quality of the colour; for example reds can be adjusted to a pinkish magenta tone to orange. Using the targeted adjustment tool more than one slider may move depending on the different tones that make up that colour.
Using the targeted adjustment tool on the red tip of the leaf in the picture above, adjusts both the red and orange tones.
As with Hue, Saturation adjusts the global saturation of each colour, increasing the saturation makes the colour stronger and decreasing saturation weaker, until grey. This can be a good way to tweak the saturation of an image; for example if magenta is too strong, you can selectively lower it. Also if you wish to make one colour much stronger you can do this here as well.
In the picture above I reduced the saturation of all the colours except; red orange and only half the strength of yellow, giving an interesting effect. Using the targeted adjustment tool will also adjust more than one tone.
Luminance allows you to adjust the brightness of colour tones, in the same way we can adjust the hue and saturation. This is good if you have one particular colour that is clipped in the histogram ( clipping is when the tone has become pure white and loses all colour information), you can use luminance to bring it back in.
I once again adjusted the orange yellow tones, this time in the back ground using the targeted adjustment tool to make them darker, to give more separation between the foreground and background.
Color allows you to do everything that you can do in the HSL tab, with the hue, saturation and luminance grouped together for each colour. Any changes made in the HSL panel are automatically changed here vice versa. The only difference being that in color there is no targeted adjustment tool.
When to use?
Adjusting the saturation of an image is usually something everyone will do and every image needs. The HSL Color Panel allows you to tweak those tones and/or completely stylize an image. In combination with Curves this can become extremely powerful to create a specific colour pallet for an image.
How much I use it depends on the picture; if the blues are lacking in the sky, I can give them a bit of a kick. Or if the green of the grass is too dominant and contrasting too much, I can adjust the hue to make the green more complimentary and bring down its strength slightly. Really I use it to create a more rounded image.
