Unsharp Mask and High Pass filters combined

Different sharpening techniques make the world look different. A world of difference can be seen between the thin hard line of Unsharp Mask and the broad feathered line of High Pass Sharpening.

Can you choose a combination of both? Yes you can! You can choose the texture of one, the halo of another, and the line of yet another, applying them either globally or selectively. You can customize the look and feel of detail in any image or image area with astonishing precision and flexibility.

    Hi,
    thanks a lot for your detailed blog posts on sharpening. But I’m a little confused on the order of sharpening. As you wrote on former posts to start with an unsharped mask with a higher radius, then lower radius and then high pass as needed. In this post here you say a classic method is to start with usm at a low radius und the next step with a higher radius. Which order is the correct one?

    Hi Markus! For double pass sharpening start with a high Radius and a low Amount (be conservative as this won’t be the final result) and then add a second pass with a low Radius and high Amount (for the final result). You’re basically thickening the edges with the first pass before making them crisper with the second pass.

    Thanks for the clarification.
