Sharpening is one of those parts of digital photography on which everybody has their own opinion. How much, when in the process to do it, using what method, selective vs global, and even whether to apply sharpening at all. Whichever method you choose (or don’t), it’s always good to know multiple methods. When your chosen technique isn’t working, knowing another way can save the day.
In this video, Colin Smith from Photoshop Cafe shows us a sharpening technique using Photoshop’s High Pass Filter. Personally, I love this method, and I’ve been using a variant of this for a few years now. It offers me a lot more versatility than most of the other sharpening methods, and it can be done non-destructively.
