DxO PhotoLab 3: The New HSL Tool

DxO PhotoLab 3 has just launched, and with it come some very exciting new features — the most colorful one being the new HSL (Hue / Saturation / Luminance) tool! In this article I’m going to show you just what it can do.

The New DxO PhotoLab 3 HSL Tool

Before getting into using the new DxO PhotoLab 3 HSL tool, let’s have a look at what it is! Here’s a tour of the interface.

Color channel selector (white selected) — When it’s white, you’re manipulating all. Notice how Luminance and Uniformity are disabled, as well as the hue range selector. Color channel selector (red selected) — When you choose a color chip here, that corresponding color range is selected on the hue wheel. This is the color range you will be manipulating. Note that each of these “chips” are presets, but each can be adjusted. Primary hue selection range tool — These two inner selectors define the range of color you will be manipulating. Feathered edge of the hue range — By moving these dots, you are expanding or contracting the extent of feathering of the color range. Hue rotation slider — This rotates the hue through the color wheel. When the “white” channel is selected (left screenshot), this will rotate all hues. When a color range is selected (right screenshot), this will adjust only the selected hue range. Saturation slider — Increase or decrease the Saturation of the selected hue range. Luminance slider — Increase or decrease the Luminance of the selected hue range. Uniformity slider — Compresses or expands the colors in the range selected, making the more alike or more different. This is generally used to even out skin tones, and make skin appear more uniform in color. Reset button Selective Color Enhancement: A little saturation goes a long way

Let’s put it to work! We’ll start with something simple; just adjusting the saturation of a color range. Let’s make the purple flowers more saturated. Here is the original image:

To adjust the purple, it’s as easy as selecting the purple chip in the HSL tool, and increasing the saturation slider, like this:

Notice that I also lowered the Luminance a little bit, to make it darker and more realistic.

Selective Color Shifting

Next, using the same photo, I’ll rotate the hue. I’ll start by simply dragging the hue rotation towards blue:

Notice that I also reset the Saturation and Luminance sliders, by simply double-clicking the slider handle.

I think it’s important to have a closer look at the image though. Zoomed out like this, if the color shift wasn’t perfect, it’d be easy to miss. So let’s see it up close, at 100%:

This looks amazing, but if I pan over a little bit, you’ll notice that there is a tiny bit of purple from the original flowers still poking through. It’s not much, so a little expansion of the feathering slider and a slight expansion of the hue range should take care of
