Highpass with overlay blend is a great way to sharpen, but I don't understand why it is claimed to be edges only. Highpass passes non-edge points too doesn't it. If the highpass module had something like a speckle remover, I could see it, but without that, I don't see why edges should be preferred. What am I missing? --alan ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
