Yesterday, World Press Photo announced that "after careful consultation with the jury, [it has] determined that is was necessary to disqualify Stepan Rudik, winner of the 3rd prize story in Sports Features, due to violation of the rules of the World Press Photo Contest." Rudik won the prize for his story "Street fighting, Kiev, Ukraine".

The organisation added: "Following the announcement of the contest results, it came to the attention of World Press Photo that Rudik's story had violated a contest rule. After requesting RAW-files of the series from him, it became clear that an element had been removed from one of the original photographs."

Speaking to BJP, a spokeswoman for World Press Photo says that the photographer had removed the foot of one its subjects from a photo. Read our full report here.

Now, the photographer has reached out to explain his motives behind the "manipulation". While Rudik does't argue the decision of the jury, he tells BJP that "the photograph I submitted to the contest is a crop, and the retouched detail is the foot of a man which appears on the original photograph, but who is not a subject of the image submitted to the contest."

He adds: "I believe this explanation is important for my reputation and good name as a reportage photographer."

Rudik provided BJP with the original photo, as well as the altered one, in a bid to show that he hasn't "made any signifiant alteration nore removed any important informative detail."

Last year, World Press Photo announced it had added a new rule that states that "the content of an image must not be altered". It added that "only retouching which conforms to currently accepted standards in the industry is allowed".
