  • Frequency Separation

    Is it destructive? Like, if You are doing with 10px brush high and low pass both, is it really destructive? Is D&B better or there isn't really big difference? I'm quite new to this technique.

    Splitting the file into low and high frequency layers is non-destructive. Modifying either layer after that is destructive.

      So high end retouch is not really possible wit this technique?

        Why would you think that? Retouching is always destructive. Doesn't mean it's bad. Depends on what you're destroying.

        Do a site search for "Split Frequency."

          I mean for skin texture, will it be damaged more after FS retouching then D&B?
          Thanks very much, searching now

            Everything is up to your workflow and how precisely you work. If I need to be fast, I would use FS, if I wish to work realy precisely, I would choose D&B. You can also combine both techniques together ...

              Oh thanks for this post I agree, because I worked quite a long time on an image with super-small brush on FS technique, that's why I asked as well as I used colour gels, so light is colourful and I tried to get rid of some things but that just was not that good-looking as I wanted, even if I tried really carefully

                With the FS you can still work in layers and edit it non-destructively. You can dodge and burn with a layer on top as you are used to if you want.

                The FS just gives you the extra option to edit low/high frequencies separately (I usually find it useful when I need to quickly smooth skin tones).

                With a regular FS there will be some colour information on the high frequency layer, and it sounds like that is what you had trouble with in your colourful image? If this is a problem, make sure you move the colour information out of the high frequency layer (I believe this is sometimes referred to as asymmetric split?).

                  This is my FS technique with non D&B at 5-10px healing brush. Also, added some contrast to high pass to make it a bit sharper. Actually, does not look like destructive. Just some really minor things.

                  Oh yeah, thanks a lot, completely forgot that it can have some colour!

                  What do you think about this? My screenshot attached.

                    Looks great from what I can tell. Cleaned up that rather nasty skin really well.

                      I was trying to achieve that dolly and vivid Mert&Marcus look but can't really say, what do you think< retouchpro-ers?
