The purpose of photojournalism is that it tells you so much more than a newscase for the same theme. When you see a photo of extreme poverty you will understand the importance of helping them instead of reading a report whit another person sight. Photojournalism is often used to document things and show the world how it really is.
This photot shows us an old man sitting on his bed in a distroyed house. Maybe his house has been through a war or he had found a empty house. This gives us a strong massage from the war and the big poverty.
