Good editorial notion, but disappointed with shallowness and jumbled nature of much of the content - a disappointment from this author, whose 'Photography - a cultural history' is first-rate. I suspect dodgy editing and the constraints of a formulaic packaging which got in the way of authorial integrity. However, she's shaky on the technical history with a page on lenses that tells you almost nothing, and fails to reference the crowd of photographers using super-long lenses shown on the page. And there's that embarrassing blooper of using a Leica A to illustrate a spread on the SLR, even referring to it as the first commercially successful SLR.
Mary has chosen well in her selection of 100 ideas. All had a significant impact or were at a turning point in the history of photography. Her books are always good and this one is a great overview for the both the public and the professionals.
