Selections based on detail size

Hi,

I find that usually there are two or three areas of a photo that
differ enough that they require separate sharpening. For example, if I
have a scene with a blue sky, green foliage and red rocks then I can
mask the sky, select the greens (or reds), Smart sharpen, inverse
selection, Smart sharpen and trash the mask. Or often I will have
generated enough channels and paths during routine editing that when
it is time to sharpen it is easy to make selections based on those
using Calculations. But there are often times when I have an image
with variations that do not lend themselves to selection by color or
easily defined edges. What I would like to do is be able to select
areas of an image base purely on the size of the detail within the
image. Does anyone know of a way to do that?

Thanks,
Ron

not sure how to do what you asked but
you could make 3-4 layers of varying sharpness on the same image
and then use masks to hide/reveal the parts you like from each one

I have tried the little sharpen tool (inside blur, smudge flyout) on some
small details like a shirt logo, piece of jewelry or just one eye
directing with the mouse by hand

Good idea, I will use it, but I would still like to find a way to
select by detail size.
I do not like the sharpen tool - not my style.
