For example, shooting down on a character creates a feeling of superiority, strength, and dominance in the audience. The character becomes small. Conversely, shooting up creates a character in the frame that appears large, strong, and dominant. Shooting as if looking up produces a feeling of inferiority, weakness, and vulnerability in the audience. Visualize the relative sizes of characters.
Relative sizes create strong emotional responses in the audience.
Keep the camera level unless you want to create tension. A tilted camera frame disorients the audience and makes them feel tense and anxious. Know which lenses and filters you want to use to capture the subject and the proper mood. For instance, a vignette filter is often used for romantic shots because it fuzzes the edges while keeping the center in focus. Make sure you can clearly see the characters.
