A single exposure from the focus sweep

The merged focus stack

One exposure · 01 / 24 Merged from 24

Exposure 01 / 24

Wipe 50%

Each exposure puts a single thin plane in focus — watch the sharp band travel from the front legs to the back as the sweep runs. No one frame shows the whole specimen. Merging all 24 recovers a single image sharp throughout, and it is that merged image, repeated at every rotation angle, that a three-dimensional reconstruction is built from.
