I got a sneaky peak at a rather exciting looking book on the Thames & Hudson stand at the London Book Fair this week. Magnum Contact Sheets will showcase the workings of the agency's legends including Henri Cartier-Bresson and Elliot Erwitt alongside newcomers like Alec Soth and Trent Park.

As a photographer I find editing a real challenge so I like the idea of being able to look at the selection process behind great images, viewing them in the original context of an entire set of negatives or slides and seeing the ones that didn't make the cut. The enlarged selected photographs are featured alongside allowing you to see adjustments to exposure and framing. In the world of digital, the integrity and physicality of the contact sheet is lost so there is a certain nostalgia about this book too.

Magnum Contact Sheets was unfinished but is predicted to publish in Autumn this year - a hefty tome with a hefty price tag of £95 but definitely one for the wish list.
