In recent years growing numbers of photographers have sought to frustrate habitual viewing habits and assert the presence of the photograph’s surface. Their work can be read as an enquiry into the limits of the photograph's transparency.

The work of Dryden Goodwin - in which layers of markings are superimposed on images - appears to explore such concerns. Guy Lane reviews Cast, a collection of his hybrid pictures.

In a rare interview Andreas Gursky talks to Guy Lane about an exhibition of his work in which many of his wall-sized prints are for the first time scaled down to modest proportions.

He discusses the influence and legacy of Bernd and Hilla Becher, and how far he has journeyed from their example. And he explains how he persuaded even the North Koreans to accede to his designs.

British photographer Paul Graham has spoken in the past of his interest in working where the interests of documentary and art meet...'the point where they coalesce. That's where photography is so powerful. And it's not a small area; it's a huge area, that can still be pushed, chipped away at, refined.'

Guy Lane looks at a comprehensive overview of his work that surveys the range of his photography - from the ground-breaking A1 of the early 80's to A Shimmer of Possibility, the winner of this year's Deutsche Bourse prize.
