Sharpening in lightroom

First let me mention something that I am currently ignoring. When I do focus stacking, I use lightroom tethering to collect raw files. I then convert them to TIF, but I do no sharpening or processing whatsoever. So I am getting whatever the lightroom default processing is when it does the conversion. Is this good or bad? I don't know.

Once the stack is done and saved from Zerene, I import the result into lightroom (a second phase of lightroom processing) and work on it. One of the final stages of this second phase is sharpening, and that is what this article is all about. I always enjoy Scot Kelby's writing style, and found this article interesting:

I'll also note that Kelby offers a comprehensive course on lightroom sharpening (which might well be worth the money).

But first, the 3 places. The first is "capture sharpening". This is what you encounter in the develop module of lightroom in the "detail panel". You get 3 sliders: Amount, radius, and detail. I usually just bump up amount past the default of 25, but this depends on the image.

The second place is "local sharpening". Here you are using the adjustment brush to add sharpening to selected areas. The tip here is to add sharpening to psychologically important areas and it makes the overall image seem even sharper.

The third and last place is "output sharpening" which you do when you export an image or use the print module. Kelby says he always uses the "high" setting here, which is exactly what I have been doing.
