I was taking still pictures of a duck eating and swallowing a fish with a Nikon D4 camera at 11 fps. There is a whole lot of almost identical images and I was thinning out and deleting the excess duplication. then I wondered if instead, such series could be used in a brief movie, either by a fast seamless slide show. Or in PP blending the image series, perhaps interpolating between them.
I remember that my first Apple 2e computer had the ability to blend one drawing you made into the following so it seems that there should be such a capability somehow.
