Mirror Anamorphosis

Mirror anamorphosis, also called catoptric anamorphosis, is a technique in which a radically distorted image painted or printed on a flat surface reconstructs into its true, recognisable form only when reflected in a curved mirror, most often a cylinder placed at the centre of the image. The viewer looks at the mirror, not the flat original, and sees the resolved picture appear on its curved surface. It works because the flat distortion is the precise mathematical inverse of what the cylinder's curved surface does to light. The image is wrapped and stretched around the mirror using a polar mapping; the reflection unwraps it. Get the geometry exactly right and a smear of paint becomes a face. For Jonty Hurwitz, mirror anamorphosis is a signature method, and the cylindrical mirror is not an accessory but an integral, inseparable component of the finished sculpture: the artwork only exists in the moment of reflection.

What is cylindrical mirror anamorphosis?

Cylindrical mirror anamorphosis — also called catoptric anamorphosis — is a technique in which a heavily distorted image on a flat surface reconstructs into its true form only when a polished cylindrical mirror is placed at its centre. The viewer looks at the mirror rather than the image, and sees the resolved picture on the curved surface.

How does a cylindrical mirror correct the distortion?

The flat artwork is the exact mathematical inverse of what the cylinder does to light. The image is wrapped and stretched outward using a polar mapping; the mirror unwraps it, compressing the smeared paint back into a legible figure.

Why do artists use a mirror instead of a fixed viewpoint?

A mirror makes the illusion portable and repeatable: any viewer standing in front of the work sees it resolve, rather than having to hunt for a single spot in the room. In Jonty Hurwitz's sculptures the cylindrical mirror is an integral component of the artwork, not a viewing aid — the piece only exists in the moment of reflection.
