- Photoshop offers lots of ways to sharpen images. Unsharp Mask, Smart Sharpen. But the best way to sharpen people, faces, and portraits is High Pass. Why is that? How do you maintain smooth skin? And the key to it all, what’s the ideal Radius value? All is revealed in this video.

wow, very in depth!! you're the man!
Just excellent Deke. Thanks for providing the summary slide of steps.
In this example, her left eye is still a tad soft. What would be your 'next step' if you wanted to do that eye a bit more.
Thanks again.
Good news! As for that eye, I’d isolate it. (Soft mask is fine. Otherwise, you’ll over-sharpen the rest of the image.) And then repeat the steps, though possibly w/out Reduce Noise. Alternatively, you can try Smart Sharpen to give it a little extra “pop.”
Great tutorial, Deke, as usual. Thank you!
My pleasure!
This is worth a try so I will write an action incorporating a Smart Filter and be happy. Thanx, Deke!
Great idea!
Fantastic. Just for curiosity and because I really like this kind of geek stuff. Why 1/5 of the total of Mpx?
I’m starting with the premise that, these days, a typical “high-res” image is 24MP. Such an image typically requires a Radius of 3.0 to 6,0px, depending on such variables as detail (vs) noise. 24/5 (or x0.2 aka 20%) gets you 4.8px, which is a safe average. That way, wherever you go from there-downsampling for screen, inkjet output, prepress-you have a image that looks tactile, but not brittle.
