Reverse Perspective Distortion Portraits with a Giant Lens

Date: 2023-05-31

When people are taking portraits, perspective is something they take for granted. But could we remove or even reverse it? And how would that look like? I've built a giant hypercentric camera with a Fresnel lens that allows to take portraits with a reversed perspective. The farther away, the larger these objects appear. Your head starts to deform and your ears are bigger than your nose.
