Your career starts at a junior level. You will be a second assistant cameraman. You will assist the cameraman and the leading cinematographer. You will help them find the right camera for the right shot. This will help you understand the different types of cameras used in various situations. You will also learn about the angles used while shooting.
You will grow as an assistant cameraman. The duties stay more or less the same as those of a second assistant. However, you will be shouldering more responsibilities. You will now transcend into a cameraman. You will follow instructions given by the cinematographer. You will adjust the angle and decide on the type of camera to be used, based on the instructions provided by the cinematographer.
After gaining experience as a cameraman, you will become a cinematographer. You will at this point be the EYES of the director- he will see his ideas come to life through your camera.
As you gain experience, you will get more films and assignments.
