Live from the Inverness darkroom: a demonstration of the early photographic process – the Cyanotype. The process involves placing objects on paper soaked with iron-based chemicals, for gradual exposure in the sun’s ultra-violet light. It was invented in 1842 by the astronomer and chemist Sir John Herschel as a first system of photocopying (hence the term blueprint). Photographer Matt Sillars from the Inverness Community Darkroom demonstrates how it works and shows the beautiful images that can be produced today.
This event is part of FLOW Photofest, the month-long photography festival held biennially across the Highlands & Islands and Moray, showcasing work produced by photographers of or from the north.
