Apple Photos Pinch to Zoom Interaction

This interaction demonstrates direct manipulation through pinch-to-zoom gestures in Apple Photos. As the user pinches outward, the photo grid dynamically scales up, transitioning fluidly from a dense multi-column layout to a larger thumbnail grid, and finally snapping into a single-photo view. The transition uses spring physics to handle the momentum of the pinch, ensuring that if the gesture is released mid-way, the grid snaps cleanly to the nearest logical zoom level. Headers fade out and reposition, and the layout morphs smoothly to maintain visual continuity.
