the unsharp mask

n. the tendency for special networks to magnify unexpected personality traits of people you know, a consequence of compressing someone's raw persona into a low-res digital format, which can randomly brighten their outer glow, sharpen their comic edges, darken their shadows, or add motion blur to a stationary life.

In digital photo processing, unsharp mask, is a filter that combines the original negative with a blurred positive image. The resulting image may look sharper but is actually a less accurate interpretation of the subject.
