Sony A7R V: Pixel Shift Capture and Workflow and Post Processing Steps
re: Sony pixel shift
This page covers workflow for Sony pixel shift particularly for Sony mirrorless cameras supporting Sony motion correction.
However, the workflow steps also apply to any camera with pixel shift, so long as you have access to at least one of the single-shot frames of the multi-shot capture.
UPDATE: link was bad, fixed.
