They say journalism is like swimming. It cannot be learnt by reading text books that explain theories about it sitting at your desk. You have to jump into the pool, in case of swimming and into the field in case of journalism. But in the beginning you must wear a safety device around your waist when you learn how to swim.

And in case of journalism, you must carry this practical guide with you, in your mind, when you jump in the field with a camera or a camera-person.
