Plan camera changes during a product comparison

Camera changes should preserve the viewer's understanding of which product is being compared and what changed between shots.

A practical procedure

1. Assign a wide comparison view and a detail view to specific explanation points.

2. Keep product labels visible across both views and rehearse the operator's change cue.

3. Return to the shared view before summarising the difference, so the comparison remains grounded.

Worked example: a fictional session

A fictional bottle comparison starts with both models, cuts to each lid mechanism, then returns to both bottles for the capacity recap.

Check the limits

Changing magnification between products can create a misleading impression of their relative size.
