Twelve Woodburytypes from the Theatre magazine of 1878 - Mr & Mrs Kendal, Miss Litton, Mr Henry J. Byron, Miss Marion Terry, Mr Hermann Vezin, Miss Roselle, Mr Farren, Miss Fowler, Mr Terry, Mr Henry Irving, Ellen Terry.

The Woodburytype process was developed by Walter Bentley Woodbury (b.1834, d.1885) based on a series of patents from 1864. The process sits between being photographic and photo-mechanical; it can be thought of as producing carbon prints mechanically, on an industrial scale. It is a continuous-tone process, no screen or ground is used.

A relief image, from a photographic negative, was produced in bichromated gelatine, this was placed in contact with a lead block and subjected to considerable pressure in an hydraulic press. The result was a lead mould varying in depth in proportion to the tonal areas of the original subject. Pigmented gelatin was placed in the mould and transferred to paper using a press. The Woodburytype produced a continuous tone image consisting of varying depths of gelatine, as no screen or ground was required the result was indistinguishable from a carbon print. The gelatine relief could be re-used to produce further lead moulds.

Woodburytypes were normally printed on thick paper or card, they could be produced in any colour but most often they were in a sepia tone that resembled a photograph, an extra coating of gelatine or similar was often applied to the finished print. Due to the pressure needed to create the mould the images tended to be small. Woodburytypes were most suitable for high-quality reproductions and were typically used for book illustrations, cartes de visite and also lantern slides. By the 1890s its use in book illustration was declining as processes such as photogravure proved more economic.
