3-Successful photojournalists need to understand that the point of photography is to tell a story in an interesting way that will entertain and draw viewers in.
4-Photography connects people all around the world. A large group of people could view the same photo, and evaluate it in a number of different ways. These people can converse and tell each other about what they can take from the photo, and how their perspectives change the meaning of the photo.
