Radial lenticular blending effect

Summary

Another continuation in the rotation-effect lenticular family. The shared idea is that, as the viewer tilts the print, a group photograph zooms inward while a separate individual portrait fades in radially — with both effects sharing the same radial center, so the transition feels like one continuous motion rather than two competing ones.

This continuation narrows in on the photographic workflow it serves. Conventional lenticular zoom requires a single high-resolution source image with a manually identified target region. Portrait photographers don’t work that way — they shoot a wide group frame and a tight individual frame separately, with no coordinate ties between them.

The added claims cover the integration of those two independently-shot images into a single lenticular print using a pixel-wise alpha-channel blend, plus the ability to control how the fade boundary progresses — from a gradual vignette to a more abrupt edge — so the same base technology can serve different product styles without changing the underlying capture pipeline.
