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

What a nice setting, Lea.  

I've been struggling 
a lot with the Unsharp Mask function, trying to find the right balance between 
the individual settings.  But playing around with three figures can be 
really tricky.  

Typically I would tend to overdo it a 
bit, with settings more like 90, 5.5, 6.  Then I would backtrack 
in the "Fade..." function.  But I've never been really satisfied with 
the end results. 

I've just tried your combination on one of my picks 
and it seems much more effective.  Something like a more "gentle" 
treatment of the image. 

Thanks for the info.

Guy

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.
