As in edition twelve, images take center-stage – after all, pictures are what Enter is all about.

Again, we feature five galleries from former participants of World Press Photo's education program.

And what variety they contain.

Among this edition’s offerings are the Iraqi mothers photographed in prison with their children. Many of the youngsters were born in jail and live there for up to four years.

Then there are the strange stone graffiti monuments in a Belarusian forest. And the man who makes leather footballs in Nigeria for a living.

As usual, Masterclass features a role model amongst those who have attended a World Press Photo Joop Swart Masterclass.

And Picture Power again highlights images which have accompanied big stories in various publications and photo editors explain why they stood out.
