Adams began to photograph in colour in the mid-1930s. He did significant personal or creative photography in colour & his distinctive visualisation of a scene & technical mastery is immediately evident in these photographs. Overall he made nearly 3 500 colour images but only a small fraction have ever been published. Adams thought seriously about publishing his colour images but the task was not accomplished during his lifetime. The Ansel Adams Publishing Rights Trust
- with advice & counsel from John Szarkowski former Director of Photography at New Yorks Museum of Modern Art; David Travis Curator of Photographs at the Art Institute of Chicago & James Enyeart former Director of the International Museum of Photography at George Eastman House--asked the distinguished master photographer Harry Callahan to select the best of Adams colour work for publication in this book.
