The HSL sliders are a powerful way to change the mood and tone of your images quite quickly in Lightroom. This awesome video tutorial will introduce you both to the theory behind them and how to use them to create images that better match your creative vision.
Coming to you from Signature Edits, this helpful video will introduce you to the HSL sliders in Lightroom as well as the theory behind how they work. HSL stands for "hue, saturation, and luminance," and they offer you a great way to control those aspects of the global colors in an image. For example, I frequently pull the luminance of the blues down in my landscape shots to give the sky a bit more punch. As the video mentions, take advantage of the targeted adjustment tool. Most colors in an image are combinations of two or more of those listed in the sliders, and using the tool takes the guesswork out of trying to find and change the right constituent colors in the correct ratios. Remember that the Lightroom adjustments work globally on the image; if you'd like to target a specific area, pop over to Photoshop, create a Hue/Saturation layer, and mask it in.
