  1. You're missing the point of what frequency separation is. If you create frequency separation with one type of blur and then use as the low layer an image with a different blur, combining the two layer will result in a different image. Try doing what you describe with a radius of 10px or more and see the effect.
  2. I Step 1 and 2 can be replaced by a 50% grey layer, blend as luminosity or color. As to the practical side of it, I use the Luminosity layer to dodge and burn (without being distracted by the color of the image), and the Hues image to see if any hue is out of the intended color harmony for the image.
  3. As far as I can tell, the values are the same for 8bit, 16bit and 32bit In Photoshop apparently there is the need for different values for each bit depth version (I haven't tested it) In the tests I've carried in Affinity, the values work exactly the same way independent of the bit depth of the image.
  4. I've noticed an issue with the Frequency separation filter. When applying the blur, it is limited to the bounding box of the pixel layer and not to the canvas. This does not happen when using gaussian blur. See attached video for detail FS.mp4
  5. I don't understand how you can use a Live filter with Frequency Separation. Can you let me know? Thank you
  6. When using the frequency separation dialogue, it would be great to be able to chose the type of blur to apply: Gaussian, Median or Bilateral, since each as a different effect on the edges. Thank you
