Camera basics aka cinematography.

In the 1920's German filmmakers moved the camera within the shot for psychological and thematic reasons.

Camera movements:
Pan, crab, track/dollying, zoom in/out, ped up/down, tilt up/down, handheld, crane, steadicam and aerial.

Camera Angels:

These are used extensively to communicate meaning and emotion about characters.

Low angle shot: Looking up at a character or object, often to instil fear or awe in the audience.

Straight and high angle shots: Looking at an eye-level angle to a character or object, giving a sense of equality between subject and audience; high angle shot. Looking down on a character, often to show vulnerability or weakness.

Canted or oblique angles: The camera is tilted to show the scene at an angle. This is used extensively in the horror and science fiction genre. The audience will often not consciously realize the change. This is often referred to as a 'dutch tilt' or 'going dutch.' The most obvious and frequently use of this technique is found in the 'Batman' television show, and original movie (when the villains are on the screen.)

Emotion comes directly from the actor's eyes. You can control the intensity of that emotion by placing the camera close or far away from thos eyes. A close up will fill the screen with emotion, pulling away to a wide angle shot will dissipate that emotion. A sudden cut from wide to close up will give the audience a sudden surprise. Sometimes a strange angle above an actor will heighten the drama.

Choice of shot size is also directly related to the size of the final display screen.
