Lee writes "This whole idea makes sense to me only if the camera has a
large lens diameter-to-aperture ratio such that the sensor image is
entirely in focus anyway."
Yes, otherwise it would be very silly.
"...can it generate pixels for highly-contrasting edges from within a
large gradient area (sharpness would not qualify for this)?"
I would imagine that was simply a software issue.
"So if the idea is to offer a user-selectable bokeh derived from a
well-focused image, that would be understandable to me, but if the
idea is for the camera to put into focus what comes from the lens
originally as out-of-focus, then I wonder."
That's pretty much what I figured too, except that -- outside of
certain episodes of The X-Files -- one cannot further "enfocus" a shot
that wasn't focused.
I cast a hairy eyeball on the few folks I've seen on other lists
talking about how this lets you put the focus on anything you want. I
think "well, yes, I guess that's sorta true, but if the shot's out of
focus, then you can unsharp-mask until the cows are built of razor
wire and you don't get a better image than you shot."
Cheers,
