FOCUS AREA
Make selections based on sharpness
This brilliant tool works by seeking out areas of sharpness, so if your subject is against an out-of-focus backdrop, the tool can select it in seconds. It can be very handy when you want to do some sharpening: there’s no point in sharpening the blurry areas of an image because all you’d be doing is amplifying the image noise in these areas. By first isolating then sharpening just the infocus areas, you can zero in and crisp up the detail that matters most.
