If you really wanted to do it the perfectly color accurate way, you'd need to do something like this: The tradeoff is that areas with high brightness or saturation values get muted quite a bit. I was hoping that the effect would be barely noticeable with your images, but since I don't know anything about the kind of material you're working with, I was actually just guessing. The good thing is that it's quite easy to accomplish. That's because it's not the mathematically accurate way to separate frequencies, just something that comes pretty close. A slight loss in color intensity is actually expected with the method I suggested. Just make sure that the radius in the High Pass and the Gaussian Blur filters are sorry for being so late with my answer.

Of course, this can also be done non-destructively by using nested Live Filter Layers.

Just like with Frequency Separation, you end up with two independent layers for the high and low frequencies, but without color information in the high frequency layer. Set the blend mode of the top layer to Linear Light. Use the exact same pixel radius that you used in the High Pass filter before.Ĥ. Apply Gaussian Blur filter to the bottom layer. Check 'Monochrome' to take the color out of the high frequencies. You now have two identical layers on top of each other.Ģ. If I remember the procedure correctly, you should be able to get there by doing something like this:ġ. instead of using the Frequency Separation command, create the necessary layer modifications step by step. Since Affinity Photo's High Pass Filter does indeed have a Monochrome option, you can achieve this by setting up the frequency separation manually, i.e.
