Sharpening macro for Affinity Photo
« on: November 28, 2017, 04:30:31 PM »

Most of my postprocessing work is with scanned film images. For this I have been using Photoshop Elements. It has its limitations but it does run many Photoshop actions. There are a few Photoshop commands it won't allow such as "Fade". If the action creates a layer it only works on 8 bit files. I have both the editions of Real World Image Sharpening and purchase of the 2nd edition allows one to download the sharpening actions described in the book. To overcome some of the limitations of Elements I have purchased Affinity Photo. It seems to have all the necessary tools but they appear in somewhat different form. I have begun an effort to emulate the Fraser/Schewe sharpening actions as Affinity macros. I hope there are some folks here on LL who use Affinity Photo and are familiar with the basic concepts of Fraser and Schewe's sharpening methods who can give me some feedback. If the forum allows I will attach my macro file.

The workflow is as follows: duplicate layer, run detect edges filter, run median blur at 2, run gaussian blur at 2, rasterize to mask, create spare channel from alpha background channel, delete duplicate layer, run live filter unsharp mask at 0.8 radius and factor 4, 66% opacity, luminosity blend, and finally apply mask from the spare channel.

I have only run it a few images but I am pleased with the results. It give a subtle sharpening without affecting the grain.

Thanks for sharing this. I've imported it into Affinity and will give it a try.

Thanks, Allan, it works great. Nice edge-mask, good default settings which you can modify (via live-filter USM settings plus layer opacity). It's a pity Affinity Photo doesn't have deconvolution sharpening (smart sharpening) built-in, but USM will do.
[edited to add] Oh, I see that you also used Blend ranges to limit sharpening to midtones -- a nice touch.

I've got the Fade command in PSE because of the ElementsXXL extension that I bought separately, and can record actions as well, but the 8-bit constraint is sometimes a pain to work around.
