A worthy companion to Abbeville's three very successful reference volumes in the series - ArtSpeak, ArtSpoke, and AntiqueSpeak - PhotoSpeak is an informative, user-friendly resource. The complexities of photographic techniques, from catalogue to digital imaging and beyond, are explained in clear, straightforward language. The international groups and movements of photography are elucidated in the same accessible who-when-where-what format that has made this series so useful. And the aesthetic concepts and critical language used to explain (and often obscure) photography over the last century and a half are demystified in illuminating, enjoyable prose. A time line and a chart of all the movements complement the text and the original selection of images.
