• Snapola is an After Effects plugin that gives any layer the look of an instant photo and lets you animate its development. One keyframeable slider takes the image from blank emulsion to fully developed print, with uneven chemical spread, soft-focus edges, and color that settles as it fixes. Includes a parametric paper frame, grain, halation, and one-click presets. GPU-accelerated.
