Largest ambrotype photograph

The largest ambrotype photograph is 2.4 square metres (25.83 square ft) and was achieved by Dimitris Mina (Cyprus) in Larnaca, Cyprus, on 13 June 2021.

An ambrotype photograph is defined as a positive photograph on a glass surface, produced through a wet plate collodion process. The process is delicate and time sensitive, where the photo has to be taken after the glass is salted. For such a large piece of glass, a large camera was required as well. Dimitris is a collodian photographer and camera builder who wanted to challenge himself to create this photo. The photo itself measures 1.2 metres wide x 2.0 metres long and weighs 50 kg. The process took place in Dimitris's studio.
