I don’t recommend that many photo books as ‘must haves’ for serious photographers but “Magnum Contact Sheets” is one of them. Released a while back as a monster sized edition the £100 or so price tag put many people off. It has now been released as a compact edition (but with 16 more pages bringing the total to 524!). Once you’ve finished looking at all those lovely images and seeing the thought processes of the photographers you can always use the book as a handy step. Buy your copy whilst you can get hold of one!
