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.
