Bandstop Processing a.k.a. Spatial Frequency Separation
I found this while looking for something else. It's a step-by-step to achieve spatial frequency separation for skin processing, sharpening, etc. that I use on my images. This tutorial doesn't use layers for each of the steps but the result is the same.
Have fun!
thanks Charles!
ReplyDeleteinteresting approach that begs an Action.
i'm still liking this approach better because the approach is to create (i think) a high and low pass, and then because they are different layers, you blend them variably using opacity.... so, instead of say removing 8-25 as in this example, you set 8 and 25 variably through sliders:

when you get down to it though. how you paint the black/white mask ends up being more art than science -- the science just gets you 80% of the way there quicker IMHO
