With the 15 September submission deadline looming for the BJP's 2011 International Photography Award (IPA), we decided to check in on some recent past winners.

Walter Astrada,who won the single image prize two years ago, has just been awarded a $20,000 Getty Images Grant for Editorial Photography. He is one of just five winners this year, announced at Visa Pour l'Image photojournalism festival in Perpignan; the other four were Stanley Greene, Liz Hingley, Joan Bardeletti and Alvaro Ybarra Zavala. All five have been given $10,000 to produce a personal projects over the next nine months, and will be given the other $10,000 on completion. Astrada will use his prize to continue his work on violence against women, with a new chapter focussing on Norway.

Michelle Sank, who won the single image award in 2010, has just published a book with Schilt Publishing called The Submerged, which features images taken around Aberystwyth in mid-Wales, and an introduction by Liz Wells. Images from The Submerged will also go on show at London's Hotshoe Gallery from 06 - 29 September.

Edmund Clark, who won the series award in 2009 with a work-in-progress called Guantanamo: If the Light Goes Out, published the finished project as a book last year with Dewi Lewis Publishing, which went on to be nominated for Best Book of 2011 by Diane Dufur of Le Bal at the International Photobook Festival in Kassel, Best Book at the 2011 New York Photo Award, and Best Books of the Year at the 2011 International Photobook Festival. He was also awarded the Hood Medal by the Royal Photographic Society and the Best Personal Work prize in the PDN Annual.

Clark has continued the Guantanamo project, in which he photographed former detainees' houses as well as the empty cells and rooms of the prison itself. Click here to see the If the Light Goes Out project and more information about it, can be seen at this website.

BJP's International Photography Award has no theme and photographs can be captured in any format, film or digital, style or genre. Anyone can enter, amateur or professional, from the UK or abroad.

There are two categories: one recognising a coherent series, the other an exceptional single image. Photographers are welcome to enter both categories and submit multiple entries, and win an exhibition printed by one of Europe's leading fine art labs, Spectrum Photographic, held at Host Gallery East London.
