This photo of the cut flower variety 'Anna' was made using the 1850s photo process called Wet Plate Collodion, a process that requires pouring a hand-made emulsion on glass which is then made light sensitive by immersion in silver nitrate. The process has to be completed in about 10 minutes or less, before the plate dries out.
