Understanding of Cameras

Aperture- This is the amount of light that a camera lets through its lens. It is the size of the opening and can be adjusted. The larger the aperture, the more light is let in, so it is good for dark photos at night. It is measured in F/stops at measurements like this 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16.

Shutter Speed- The measurement to determine how long the shutter is open for when the picture is taken. The faster the speed, the shorter the exposure time. The shutter speed and aperture
time control how much light reaches the sensor.

ISO- The sensitivity of the image sensor. Setting the ISO level will tell the camera how much light is needed for a good image. The higher the ISO the less light required. Low ISOs are often needed in bright situations.

Lens- The part of the camera where light travels through to reach the sensor. The lens can allow you to decide how much of an image you can capture. Wide angle lenses are particularly good for scenic and wide landscapes. Portrait lenses are good for close ups of people as they minimise distortion.
