Photography Practice with your camera as we go along! Aperture, Shutter Speed, and ISO
Aperture • The opening and closing of the lens. • The more open your aperture, the more light that is let in (kind of like the iris/pupil of your eye). • The “F-Stop” is the size of your aperture. It’s shown on your camera as something like “F 4.0” • The smaller the number, the bigger the F-Stop and vice versa.
Why change the aperture? • In low light situations, open your aperture more (small F-Stop number) to let more light in. • In a landscape where there is lots of light, you can close your aperture (bigger F-Stop).
Shutter Speed • Compare the camera’s shutter to your eyelid. • Faster shutter speeds can be used for action photography. Slower could be used when you want to capture light, such as a sunset. • Slower shutter speeds can be used in low light (a similar effect to lowering your F-Stop). • Fast shutter speeds will need a brighter environment. • For super-slow shutter speeds, you should use a stable base or a tripod. You may also want to raise your F-Stop). • Shutter speed is represented as a fraction of a second: 1/50 or 1/4000
ISO • ISO refers to how sensitive your image sensor is to light. • The higher the number, the more sensitive your image will be. • Use low ISO in daylight (you don’t need artificial light). • Use high ISO in a low-light situation (concerts, sporting events).
