P: Focus mask / image sharpness

Like a topographical map, except instead of showing altitude, show sharpness/in-focus-ness.Would allow one to see at a glance where the focal plane lies, and how well focused is the photo at the focal plane (and everywhere else), and what is the depth of field.PhaseOne took a whack at this in CaptureOne. I think their implementation has some weaknesses: shows focal plane, but no indication of how well focused at the plane, and gives no sense of depth of field, but is still quite useful.See http://feedback.photoshop.com/photosh... for a related idea, that would go nicely with this one.If you like this idea, please remember to click the '+1' button below.
