1. Pans1. Pans

A movement which scans a scene horizontally. The camera is placed on a tripod, which operates as a stationary axis point as the camera is turned, often to follow a moving object which is kept in the middle of the frame

3. Dolly Shots3. Dolly Shots

Sometimes called TRUCKING or TRACKING shots. The camera is placed on a moving vehicle and moves alongside the action, generally following a moving figure or object.

A dolly shot may be a good way of portraying movement, the journey of a character for instance, or for moving from a long shot to a close-up, gradually focusing the audience on a particular object or character.

4. Hand-held shots4. Hand-held shots

The hand-held camera allow the camera operator to move in and out of scenes with greater speed. It gives a jerky, ragged effect, totally at odds with the organized smoothness of a dolly shot, and is favored by filmmakers looking for a gritty realism, which involves the viewer very closely with a scene.

5. Crane Shots5. Crane Shots

Basically, dolly-shots-in-the-air. A crane is a useful way of moving a camera - it can move up, down, left, right, swooping in on action or moving diagonally out of it.

6. Zoom Lenses6. Zoom Lenses The zoom lens means that the camera need

not be moved. The zoom lens can zip a camera in or out of a scene very quickly. The drawbacks include the fact that while a dolly shot involves a steady movement similar to the focusing change in the human eye, the zoom lens tends to be jerky and to distort an image, making objects appear closer together than they really are.

7. The Aerial Shot7. The Aerial Shot

An exciting variation of a crane shot, usually taken from a helicopter. This is often used at the beginning of a film, in order to establish setting and movement. A helicopter is like a particularly flexible sort of crane - it can go anywhere, keep up with anything, move in and out of a scene, and convey real drama and exhilaration.
