1.Define the meaning of aperture, shutter speed, ISO, and depth of field (DOF)
Aperture: controls the area over which light can enter your camera
Shutter speed: controls the duration of the exposure
ISO speed: controls the sensitivity of your camera’s sensor to a given amount of light
DOF: Aperture also controls the depth of field, which is the portion of a scene that appears to be sharp. If the aperture is very small, the depth of field is large, while if the aperture is large, the depth of field is small.
One can therefore use many combinations of the above three settings to achieve the same exposure. The key, however, is knowing which trade-offs to make, since each setting also influences other image properties. For example, aperture affects depth of field, shutter speed affects motion blur and ISO speed affects image noise.

2. Differentiate the purpose of camera angles and shots.
shoot is the shot angle is the level from which you look at your subject through the camcorder. As a general rule, shoot people at (their) head height.
- Eye-level angle
- High angle
- Low angle
- Tilting shot – Experiment with panning in the vertical plane instead of the horizontal.
- Forward/backward tracking shot – Try shooting a moving subject from behind, or when they are coming towards you.
Camera angles and movements combine to create a sequence of images, just as words, word order and punctuation combine to make the meaning of a sentence
- Extreme long shot
- Long Shot
- Medium Shot
- Extreme Close-Up
