• 1854 – In London, the Welsh photographer John Dillwyn Llewelyn exhibited several early instantaneous photographs of the seaside. In 1855, he demonstrated these photographs at the Exposition Universelle in Paris. His works were well received by critics, with detailed analysis of how well the waves were pictured. Llewelyn probably was an early adopter of the use of an automatic shutter, though the start date for this practice is uncertain.
