![]() I set the flow to somewhere between 30-50% and use a small, soft brush to begin blending the skin texture. The bulk of the retouch work will be done on another layer (or two), where I use the Healing Brush. Step 3: The Healing Brush Does the Heavy Lifting This will make spots and lines seem more subtle, although it doesn’t completely remove them, and it preserves all of the texture. First, I use the In-Painting brush (Content-Aware fill) to paint over skin spots, age spots, or any kind of discoloration in the skin tones. This is the layer where I will begin to apply my edits so that I can always change or undo what I’ve done without affecting the original image. Once I have my high- and low-frequency layers, I will create a new layer (called a Pixel) and place it in between the high- and low-frequency layers. Think “less is more” when applying the radius of the filter. For headshots, I generally set the radius between 4-7, but mostly, I want to eyeball it to get the high frequency looking crisp and the low frequency blurry enough that my edits will make a noticeable difference. All you need to do is set your radius, and as you move the slider, you will see the changes in real-time. This can also be done in Photoshop, but it requires a lot more steps. Just go to the menu, select "Filters," and click on "Frequency Separation." A dialog box will pop up, as well as a side-by-side of the high- and low-frequency layers. Generating a high and low-frequency layer is super easy in Affinity Photo. Step 2: Apply the Frequency Separation Filter ![]() This is why I use it mainly for stray hairs. This first step in the process is to remove small items that do not cover a circular or large area, and therefore, do not affect the skin greatly. I use this brush to remove things like stray eyebrow hairs, nose hairs that may be peeking out, or stray hairs that don’t belong across the forehead. The In-Painting brush (content-aware fill) is my first step in the editing process, even before separating any layers. Step 1: Use the In-Painting Brush to Remove Stray Hairs It's also relatively easy to do, especially in Affinity Photo. Frequency separation avoids plastic-looking or overly smoothed-out skin, so the final result remains realistic looking and true to the original capture. ![]() By using this method, you can preserve the detail in the image while fixing skin blemishes and the like. The high-frequency layer keeps all the detail of your image, while the low-frequency layer is used to apply the bulk of the editing changes. When retouching, it's important to use a method like frequency separation since it preserves the texture of the skin.What Is Frequency Separation?įrequency separation takes the information in your image and divides it into a high- and low-frequency layer.
