Why is everybody talking about it?
It showcases works by the prize's four shortlisted photographers - Pieter Hugo, Rinko Kawauchi, John Stezaker and Christopher Williams.
Is it worth the hype?
Yes, the annual £30,000 award goes to a photographer, of any nationality, for a body of work in an exhibition or publication.
Watch out for?
Stezaker's collages – he is the only British nominee.
