Any thoughts?  I'm now trying to use the "find edges" filter on another

Typically, you'd toss the picture onto a web site, and then copy and
past the URL into a post replying to the last message in your thread.

Truly out of focus can't be focussed, but it maybe can be altered to
look, ah, better, if not sharper.

An obscurish part solution is making a duplicate layer,
running the Filter->Other->High Pass(6 ish? Play around)
on this layer and then setting layer properties to overlay.
The higher the High Pass is set the darker the edges will become.

Perhaps setting an action with interaction (whatever that
little red box on the actions panel is) on the High Pass
would be the best way to experiment with this.
This does mess with your colours quite badly iirc.

Thanks Dave, I'll give it a spin.  My other attempts are in vain, so I
appreciate your feedback.  I can deal with the color shifts; just
really need to at least add some edge sharpness.

Sorry, that was completely wrong. More contrasty? Sorry, it's late here.

It gets kinda' complicated but Deke Mcclelland describes a process in the
PS 7 Bible. Here is synopsis

Dupe one of color channels
Filter>Stylize>Find Edges
Invert
Filter>Other>Maximum
Filter>Noise>Median
Filter>Blur>gaussian
Return to composite view
Convert the mask to a selection
Filter>Sharpen>Unsharp Mask - 500%, Radius 2, Threshold 0

Basically what this does is take the elements that have sharp distinctions
and makes a mask of them. When the unsharp mask filter is applied, the
smooth areas are masked out so they do not get grainy.

As always, trial and error must be employed. Sometimes, what you got is as
good as you can get.

Good luck.

Only if you leave the High pass layer in RGB. If you desaturate it (or
channel mix to monochrome) it will only affect the contrast of the
chosen spatial frequency. One can improve multiple frequencies with
multiple HP layers and, after flattening, the procedure can be
repeated multiple times.

What the OP really needs, is an attempt with a deconvolution method.
Recommendations depend on the image (size/noise), but the
timeframe/deadline seems too short/soon to find the best solution.

my thought exactly.
I wonder if de-focusing in camera lenses (if that's the term I'm looking
for) is consistent enough across various types, focal lengths, etc., etc.
that a solution with one or two parameters is possible, so that a plug in
could be devised with the usual slider or two.
If so, I'd be surprised if someone hasn't done that.
