Perception-challenging artwork

Perception challenging contemporary artwork

Shapes at the edge of perception
Papier mache, acrylic, card.    30cm x 21cm.    2021.

A wall hung piece in which a matte black hemisphere protrudes from a flat matte black surface. Due to the darkness of the surface the protruding hemisphere is quite hard to see (although in this photograph it is lit in a way that makes it reasonably visible). Even less obvious than the protruding hemisphere, the matte black circle at the centre of the metallic area is actually a hemispherical indentation. This indentation is very rarely noticed by observers.
An investigation into perception, optical illusion and expectation.
