Sharp

Sharp is an iPhone and iPad app for photographs shot more than once. Shoot the same scene several times, and Sharp puts the frames together into one picture.

A lens holds one plane in focus. Noise is different in every frame and the subject is not. A person walking through a square is in one frame out of twelve. Each of those is the same problem: shoot it more than once, and decide, pixel by pixel, what to keep.

• Focus: a stack that is sharp from front to back
• Clean: noise averaged away, and long-exposure water without a filter
• Vanish: the people walk out of the picture
• Trails: every place the light went, for night skies and light painting
• Blend: an exposure bracket into one picture; Pick: the sharpest frame of a burst
• Camera RAW, HEIC, JPEG, TIFF and PNG, with alignment for hand-held sets and a brush to paint any frame back
