A broken block of galena (lead sulphide) with brassy pyrite and an old cloth-tape label. The Before model is built the way I used to: from two hand-run rotations and a few photos. The After model uses 192 photos from a motorised turntable, shot from four angles, including upside down. Put a finger on either one and turn it. The other follows.
Drag sideways to turn, pinch to zoom. The spin pauses while you hold it and picks up again a few seconds after you let go.
With only side and slightly-above views, the software had to guess at the bottom. Flipping the rock for a fourth rotation means every face is photographed.
The new frames are full-resolution crops instead of the 1024 px web images, so the cleavage steps, pyrite grains and label edge come through sharper.
The turntable stops at 48 exact positions with the exposure and focus locked, so every frame matches the one before it.
