SPECTRA

SPECTRA explores the colours of light to be found in the natural and the synthetic. It comprises eighteen colourful images each produced in camera from a single frame as a result of:

dispersion, most commonly seen in the separation of colours by a prism

diffraction, caused by gratings and edges that are smaller than the wavelength of visible light

polarisation, typically seen on clear plastic cutlery

interference, as seen on the surface of soap bubbles
