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

[lea murphy <lea@xxxxxxxxxxxxxxxxx>]

I sharpen using Unsharp Mask in PS. My 'standard' setting for portrait work is 159, .9, 0. Everything starts here and then I move it around...but oftentimes not by much.

I typically have the image open at 100% with 'preview' checked so I can see the effect.

Just the dialog box of 'smart sharpen' was confusing to me so I never use it.

What are people doing in this area?

I used to use unsharp masking in Photoshop exclusively -- sometimes

with a fairly large radius (1-5 pixels) on the full-resolution image,

and always with a much smaller radius, perhaps .7 or 1.1 pixels for

web-resolution images.  Now with CS2 I'm mostly using "smart

sharpening", but not understanding it as well.  I know I use smaller

numbers in the dialog box :-).

Do people find it easier to judge when an image for screen use is

over-sharpened at 100%, or perhaps at 200% viewing size?  And how do

you decide how to sharpen for print?

And I expanded out to Focus Magic, which can sometimes do miraculous

things with clearly out-of-focus images (visible back-focus for

example), and also sometimes with motion-blurred images.  That's

trial-and-error, and sometimes very slow (several minutes for a

10-pixel radius out-of-focus correction on a 10MP image).  But the

results are sometimes pretty much miraculous.
