Pixel Shift has huge potential for improving image quality, but some implementations (such as Sony) are so badly done that field use is impractical, yielding flawed images most of the time.

Pixel shift is in effect a simplified version of multi-shot high-res mode. As of early 2020, the need for pixel shift exists only because it is much simpler and less processor intensive. Going forward, it is hard to see that it has any value versus multi-shot high-res mode.

Requirements:

A tripod is presumed, but might not be necessary with advances in hardware.

• Interacts and can be used with Optimal Exposure / ETTR.
• Produces a lossless-compressed pixel shift file (single file).
• Option to retain the first conventional exposure along with the pixel shift exposure and/or all frames.
• Smart detection of checkeboarding and other artifacts, rejecting or averaging problem areas.
