Key Topics to Revise
1
Working of a Camera
- A camera is a light-tight box that allows controlled amounts of light to fall on a light-sensitive surface (film or digital sensor).
- Too much light causes overexposure (image appears too bright), while too little light causes underexposure (image appears too dark).
- Two main components control the amount of light entering the camera: the shutter and the aperture.
2
Parts of a Camera
- Viewfinder: Used to look and aim the camera at the subject.
- Shutter Release: Button pressed to take a photograph.
- Lens: Most important part; focuses light onto the sensor/film using glass elements that bend light.
3
Properties of a Lens
- Different lenses provide different angles of view and magnifications.
- Wide-angle lens: Short focal length, captures a broad scene, makes subjects appear smaller.
- Telephoto lens: Long focal length, brings distant subjects closer, narrows the field of view.
4
Other Important Equipment in Photography
- Flash: Provides a burst of light during exposure, useful in low-light conditions or to fill shadows.
- Built-in flashes are less powerful; external flashes offer more control and intensity.
- Tripod: A three-legged stand that stabilizes the camera, especially important during long exposures.
