Not necessary the one you use most often which, for me is USM.
What I'm asking about is the one that works best for you. For me, it is the Richardson–Lucy deconvolution method as found in RawTherapee.

I get 95% of it done in C1 with Custom Style, usually to my lens/body based recipe, (don't know which protocol they use for sharpening).
Finish off with USM in FastStone during final fiddle.
p.s. 100% RAW here. -
I often sharpen when in FastStone Viewer, using several goes with various px settings.
-
I start with a 8 inch 80 grit grinding wheel, followed by water stones up through 16,000 grit at 30 degree bevel on the chisel with a 5 degree microbevel . . .
Oh, wait . . .
🙄
-
16,000 grit huh? almost like Teflon ...

Topaz Sharpen AI works works best for me but sometimes needs a bit of tidying in Photoshp Elements with selectively adjusting the opacity of a layer mask overlaying the original.
I also have written my own scripts using JavaScript (which both PSE & Ps support) to run sharpening and detail enhancement techniques inculding high pass filters.
But mainly Topaz Sharpen AI.
-
So that's how you get a sharp cam !
-
My pictures that I present are sharp to begin with. Those that are not get deleted.
I have tried Topaz to rescue blurry shots. They always look a bit artificial. I just run Capture One at the default settings for my camera/lens.
I prefer to reshoot if I can.
-
it depends on the subject, sometimes i use sharpening in ACR others i use usm in Ps and then my go to most of the time is preset incamera for my jpgs. back in the day with my pentax k7 no software chould sharpen an image better than the in camera software. many tried and all failed to better it.
-
If you shoot sooc then sharpening is done in camera according to the camera's "picture style" settings.
If shooting raw then all raw data requires some sharpening due to the demosaicing during the raw conversion.
Topaz's sharpening normally gives me good natural looking results but you need to choose the most appropriate model and settings for best results.

im noticing that i like the incamera jpegs for sharpening and trying to use the cameras settings on the raw file in ACR im not getting the same effect. any ideas why ACR cant match the out of camera jpegs ? im no wizz at PP so all help is appreciated.
-
I also have found that ACR's sharpening is not as effective as I would like. I don't lnow why except to guess that sharpening in ACR is not a high priority for Adobe.
The sharpening in Ps/PSE is much better but still struggles in my experience in some situations.

I'm the lazy one - I' using what my software (DXO currently) offers me.
There are two main options - 'lens softness correction' and 'unsharp mask'. Sure these are very different - first one is based on DXO camera/lens optical model and needs usually the same amount of correction, second one is just 'normal' USM - and that is rarely used. Since Sigma times I have habit to take multiple shots of same scene - at least some images are sharp enough to not sharpen them more.
While using Sigma SD14 there usually was no need to sharpen at all - well, Sigma SPP software sharpened in background and often it was even good to decrease default sharpness - not all scenes need to be needle-sharp.
-
I am pretty lazy too. I use the default Capture One setting 99.9% of the time.
I wonder if we need to worry too much when we do not crop excessively and use a high MP sensor.

Photoshop's Unsharp Mask does for me. I also found this tutorial which explains how it works (which I didn't know before) www.cambridgeincolour.com/tutorials/unsharp-mask.htm

It may depend on lens used. On Sigma I tested many old lens, some of these just didn't create sharp image - those images would have benefitted from sharpening. But as those were only tests and I didn't do any real shooting with them, then I didn't play with sharpening either.
My current camera has fixed lens, no such problems :)
I have sometimes used Corel Paintshop Pro sharpening tools - for adjusting some graphic or images, not taken by me. My favourite tool was "High pass sharpen" - but I have no clear idea what algorithm this uses.
-
When I used M43, DXO did a brilliant job with my lenses, with built in lens profiles. It was the only software that cured the green fringing when I used my Panasonic 12-35 on an EM5.

ChatGPT 3.5 explained it to me here:
-
Thank you! Looks pretty logical, at least paramters are correct and behavior matches to my experience.
Even ChatGPT may sometimes strike home.

I get '404 not found' when I click on the link.

I tried it in the GIMP using 1px, 2px Gaussian Edge Detection and Soft Light Blending.
Original
High Pass
Quite a halo, too big an edge detect maybe ... I didn't play with it much ...
-
Your original image already is a bit oversharpened (halos around wires) - high-pass just amplifies this.
You need to find some soft image and try there. Sigma images are too sharp for that :) -
Now if I could just get this as a plug-in in Photoshop . . .
