The eclectic and the curious: Selections from the Foto8 Summershow

What makes a good photograph? That's the question at the heart of the Foto8 Summershow, a self-styled Salon de photographie opening on Friday evening in London.

A few weeks ago I joined Foto8's editors to help out with the preliminary selections for this year's exhibition. It was a daunting task. Photographers from many nations and all walks of life entered a grand total of 3,226 images, of which 159 were chosen to be squeezed on to the gallery's walls for an exhibition running until August 18. Scroll down to get a small taste of what's on offer, and follow @foto8 for the announcement of the 'Best in Show'.
