The Photographic Unit provides photographic and processing services for all sectors of the Garden and operates a fully equipped darkroom and studio. Colour and monochrome photography covering a wide range of subjects, including plant portraits, general garden views, personalities, garden activities and scientific techniques, is carried out. Both studio and field photography are undertaken, and specialist underwater equipment is available for photographing marine plants. The Unit also houses and administers a 35mm slide library and a multiformat collection for both publication and commercial use. There is also an extensive monochrome negative collection, including that of the late George Forrest.
Photographic equipment is available to staff for expeditions, visits and specific projects.
In addition, advice is given on various photographic problems and procedures.
