igital pinhole photography is miraculous. The ability to form images without a glass lens allows the photographer to work directly with the particle theory of light. Light is made up of little particles that obey the same laws of physics as other spherical masses. They are minuscule, so the particles in two intersecting beams do not scatter off each other. And using a photon sieve forces the process directly into quantum field theory - particles can be generated and particles can be canceled when proscribed as a collection of harmonic oscillations.
Diffraction occurs whenever a wavefront encounters an opaque object. The photon sieve uses edge diffraction to bend light waves around a concentric series of circular edge patterns. Great magical stuff. Since the focal length of a photon sieve is dependent on the wavelength of the radiation being recorded, resultant images possess a unique dreamy softness. Technically the focal length is inversely proportional to wavelength.
“Spreading out the particle into a string is a step in the direction of making everything we're familiar with fuzzy. You enter a completely new world where things aren't at all what you're used to.” - Edward Witten
