The photographs on this wall allow a close comparison between salted paper prints and albumen prints. Fenton used both processes when printing from his glass negatives. At the time of the Crimean War photographic printing was ‘in transition’, with a gradual move from salted paper prints to albumen prints. It seems possible the commercial demands placed on Agnew’s required the greater efficiency of albumen printing, but the textured appearance of salted paper prints was still favoured, particularly by connoisseurs. Consequently, the albumen prints may have been printed to appear as close in tone as possible to the salted paper prints. It is often extremely difficult to distinguish between the two processes by eye alone. A microscope is often required to confirm initial attributions.
