Susi Arnott and I ran a photogram workshop for 250 people as part of an Elements evening at the Wellcome Collection. We turned a conference room into a huge darkroom where volunteer chemists explained silver’s role in analogue photography. Visitors could make images using what they had in their pockets, or had brought along especially, but the team brought objects along too.
Photograms have an interesting history as well as chemistry. Read our information sheet here: Photograms History Chemistry Art
