AH_Silica Gel Photography Borneo Desiccant Rainforest_8965.jpg
Photographer heating silica gel over camp fire in rainforest to restore its desicating properties. The high humidity of the rainforest can fog camera lenses and lead to mould growth, so silica gel is used to capture moisture. The moisture is then expelled from the gel by heating it, turning it from pink to blue. Maliau Basin, Sabah, Borneo.
