This is a found UK wet plate collodion. It is a beach momento and like all such photgraphs an informal - for the time - snapshot in time. This is a fine example of 1880's black tent and wet chemical beach photography. It is the photographic technology of the 1850's at it's very best. Walker can be seen relaxing with his wife on the beach at Eastbourne.
Behind him on the horizon can be glimpsed the circular enclosure for Beach Concert Party performances. This part of the beach is now under the Carpet Gardens which is along the promenade and quite near to the pier. The camera is facing east. The image is well defined with sharp deep focus, is well lit and zooms with precision. This is not a copy, this is the original HD scan.
