I just now downloaded this refocus-it rpm and installed it. While
the procedure and plugins browsers can find it, there appears to be
no way to actually execute it. It doesn't show up in the tools or
transforms menu's nor in the plugin-fu or script-fu pulldowns.
The plug-in has a different name in the menu, but I can't remember
exactly or check from here.
If you query the RPM it will tell you:
rpm -qi gimp-refocus-it
which returns:
Filters/Enhance/Iterative refocus...
And by golly there it is. I'd swear it wasn't there last night. Its
also a wee bit slow, taking what appears to be about 20 minutes to
process a 24 megabyte image I preloaded. The image, which I can't
duplicate again without several days reassembly work, had my camera
focused about 9 feet away on the grass instead of the object about a
foot away I wanted a record pix of.
The first pass seemed to indicate I needed to expand the top variable,
so I ran that up from 6 to 30, and brought the interations down to 4,
and I can't tell if its working or not, no progress bar because the
screenblanker kicks in before the refresh. 2.5 hours so far. But, if
it will do the job, its worth it.
Ok, that adjustment, at 90% done & 4+ hours into the adjustment, would
seem to indicate the adjustments I made were apparently in reverse of
the desired effect, and for some reason the contrast seems to have gone
up quite a bit too.
So my question now is, if I can measure the diameter of a specular
highlight thats supposed to be a near point src, is there a way to
translate that diameter into a set of desired variables to be applied to
this refocus routine to achieve near optimum results from a first pass?
Trial and error doesn't seem to be very productive so far.
