      1. Karl, thank you! Love your style of teaching by the way. You explains things in a way that is very easy to understand. Best wishes.

  1. Hey Karl, i normally use the Surface blur instead of the Gaussian blur, would you recomend better the Gaussian? why?

  2. hi, OK. Ive sorted it out now. I think it was the way I either duplicated the layers or made new layers

  3. Hi Karl,
    Im having trouble with my hf layer. I set up my background layer, made two duplicates, applied the gaussian blur to the lf layer. I then applied the settings for the hf layer and hit ok. all looking good so far but then when I change the hf blend mode to linear light instead of the original image popping up the image just gets too light to see. Whatever am I doing wrong ? Im working alongside your video for frequency separation
    Thank you

      1. Ok, I googled a bit and found that the solution is to put the Scale value in the apply image window to 2. By default it is set to 1. If you change that value it works.
