Duane MichalsFor those who appreciate intellectual content and emotional associations rather than purely technical aspects and visual associations of photography, this artist's got to be one of the major heros (if not the greatest one - like for myself).
I fully recommend an anthology of his works:
The Essential Duane Michals by Marco Livingstone, with 264 illustrations: 234 in duotone and 30 in color. The album has been published in 1997 by Thames and Hudson Ltd., London. ISBN 0-500-54214-7. Price: £ 36.00 or $ 56.21 (at Amazon.com).
Good place to start exploring his art could be this:
