- Define the meaning of aperture, shutter speed, ISO, and depth of field (DOF)
- Differentiate the purpose of camera angles and shots.
1. I) Aperture: Aperture is a hole within a lens. It is the measurement or size of the opening in the lens which controls the amount of light. The larger the aperture, the more lights gets in. Some lenses have fixed aperture, and some have variables apertures to control the amount of light.
II) Shutter speed: Shutter speed is the amount of time that the shutter is open or exposed to the light. It is the length of time that the shutter was exposed or sees the scene or environment that we attempt to captures. Shutter speed is measured in fractions of a second, when they are under a second. More light will enter if slow shutter speed is set, which are used for low lights and night photography. While, fast shutter speeds help to freeze motion.
III) ISO: It is the level of sensitivity of the camera to available light. ISO is measured in numbers. The lower number of ISO, the lower the sensitivity to available light and vice versa. The increasing of ISO will also contribute to the increasing of grain or noise.
IV) Depth of Field: That amount of shot that will be in focus which is controlled by the aperture. The larger depths of field means most of image ‘sees’ by the lens will be in focus no matter if it’s near the camera or far away. Small depths of field means that only half of the page or image will be in focus, and the rest will look blurred.
2. Camera shot is the amount of space that is seen in one shot or frame. Camera shots are used to display different aspect of a film’s setting, characters and themes. They ways or each shots is taken will affect the meaning or viewer’s understanding and response. Whereas, camera angles are used to set the posture or position of the viewer so it is more clear and recognizable of the relationship between the characters and the environments.
