Every day till 3 January theartsdesk will carry a survey of one of the arts we cover. We begin with Photography. Photography books are exploding on to the market like fireworks just as the book as a tangible object is becoming increasingly endangered. And with so many titles emerging from established and pop-up publishers, it’s a hard task to pin them down to the best of 2009 without some shocking omissions. So I’ll call them “Favourites” - and await cries of outrage about who’s in and who’s out.
