The Art and Practice of Silver Printing by Henry Peach Robinson and Captain William de Wiveleslie Abney is a fitting book to celebrate with, silver being generally connected with 25th anniversaries. Printed in 1881, the book gives a fascinating glimpse into early photographic printing techniques.
In our age of ubiquitous digital photography and image manipulation, it is fascinating to look back to the beginnings, when there was a lot of chemistry and craftsmanship involved in making even a single print. The book explains in great detail the whole process of getting from a photographic negative to a finished print, from preparing the chemical solutions involved and the paper, how to deal with different subjects, like portraits and landscapes, to how to mount the finished prints for presentation.
