An albumen seaside view at Boulogne-sur-Mer by Edmond Bacot was a very early example, supposedly made in May 1850. The experimental albumen glass negative showed many waves as an undefined white area in a picture with a relatively high contrast. John Dillwyn Llewelyn exhibited several early instantaneous pictures of the seaside, in London in 1854 and at the Exposition Universelle in Paris in 1855.
