Re: Sharpening, and improving focus, and reducing motion blur

David,
I agree completely about having a sharpening starting point.

This thread has me wondering, does it stand to reason that a specific lens, camera body combination would typically require about the same amount of sharpening? Kind of makes sense to me when I think about it. And that may be why my standard starting point works...because I typically use the same lens and body combo.

Mind you, I'm not trying to pull an image into focus...just sharpen it up.

I've not yet shot a raw image that hasn't benefited from sharpening.

 Interesting about trying to standardize on sharpening settings.
Using that premise it seems to me that one must expect all ones
captures to be tack sharp before processing?

I aim to not have to apply any sharpening as a start.  If I'm so
attached to an image that I can't accept that it's not sharp enough,
then I grit my teeth and apply sharpening - as little as I can get
away with.

The last time I sharpened, the radius was .08 and the threshold was
as low as Unsharp Mask permitted.

Now, it's quite clear that jpegs for web use do require sharpening.
For that at least 50% works fine.

But to me every image is a unique situation.  Percentage just can't
be standardized in my view.

My position is that every digital image requires sharpening before
use, at some stage -- maybe just in camera or in the scanner software.

I very much agree that for anything beyond proofs and snapshots, you
need to look at individual images and make choices.  Still, seeing the
starting points people think of as "normal' for different kinds (print
of various sizes, web) of images is very interesting.
