When you begin, select the low frequency colour layer and apply the brush settings as shown above. Only when you have made these adjustments, should you begin with frequency separation. Then opening the image in Photoshop I used the healing brush tool to remove obvious blemishes and the patch tool to reduce under eye circles and areas of redness. To smooth skin and even out colour and skin tones you can work on the low frequency layer without making any changes to the texture (high frequency) on the skin.įor the image below, my first step was to make small adjustments to my highlights and shadows in ACR. The purpose then of frequency separation is to separate the high from the low so that you can work on each element individually. The low frequencies are skin tones and colours, while high frequencies are textures.
In any image there are low frequencies and high frequencies. And the mixer brush tool works so well with this technique! But how does FS work? I am working on copy layers so I turn this option OFF so that the changes I am making only apply to that layer.įrequency separation is a powerful skin editing technique that can smooth skin, minimise blemishes, reduce under eye circles and blend skin tones, without losing skin texture. Sample all layerswhen working with frequency separation. A lower flow value will apply the effect slower and more gradual than a higher flow value The value of flow controls the intensity of the brush. But since i have set my brush to clean after each stroke, this value doesn’t really matter in this instance.įlowworks just the same here as with any brush. Mixcontrols the ratio of the wet/load mix. Just like with a normal paintbrush, the load runs out of paint as you paint with it. Higher values could therefor be similar to loading your brush with a heavier oil paint. So imagine you are working with light water colour based paint when you set this value lower. Loadcontrols how much paint the brush holds with each stroke. The lower this value, the less paint you are moving around. Wet controls the amount of paint that is picked up during each stroke of the brush. To fully understand how the mixer brush works, let’s have a closer look at the each setting.
