Meet the real-life sky walker - the photographer who risks his life scaling sky-high buildings to take incredible photos of the world below.
Russian student Marat Dupri, 19, bought a Canon camera 18 months ago and immediately decided to start taking shots of beautiful views.
He began climbing onto the roofs of houses to capture spectacular views from the air, before deciding to go to even greater heights.
Together with his fearless friends and models, he has sneaked past guards at some of Moscow's tallest structures - to produce incredible yet stomach-churning images.
The incredible photos show the teens walking in the sky, as they perch hundreds of feet in the air on pylons, or walking on the edge of a high building with NO safety harnesses.
Marat said: ‘When I am on the roof I have a feeling that the whole world is by my feet.
‘All my problems and trouble are left somewhere down. The height exhilarates me. I am enjoying with my home town views. It gives me energy and fills with enthusiasm to make new and great shots.
‘I had always been interested in photography and a couple of years ago, I bought my first proper camera.
‘I wanted to try and get the most spectacular pictures I could - pictures like no-one else had taken before.
‘I began by taking pictures from my own roof, but soon I wanted to get bigger and better pictures.
‘So I went with my friend to the top of a 33 storey building. It was about 120 metres high and we went right out to the edge and I started taking pictures.
‘It was such a thrill, we couldn't wait to do it again.
‘I've taken a lot of the photos by sneaking past guards and getting access to structures illegally.
‘But I think the risks are worth it to take such amazing pictures.’
Marat's incredible pictures show several of his friends balancing on the very edge of beams hundreds of feet above the ground.
They are not attached to any safety harnesses and could plummet to earth at any time.
