What is Exposure? Exposure is how much light enters the lens of a camera and hits the sensor. By doing it, it brightens up the photo taken. Low Exposure Standard Exposure High Exposure

What different aspects make exposure? Aperture, The size of the aperture effects the exposure as well as depth of field. ISO, The sensitivity of the sensor Effects the photos exposure quite heavily. Shutter Speed, The shutter speed can let more light to the sensor for longer amounts of time, Increasing the exposure amount.

Aperture The higher the aperture number, the smaller the hole in the lens to let light into the sensor and the exposure will be less. The Smaller the number, the bigger the aperture hole is and more light enters to the sensor. A lower aperture will add depth of field to the photo, Meaning the background will be blurry and the foreground will be more in focus, or vice versa If the aperture is high, there will be more detail in the photo and everything will be more in focus. But because the hole is smaller, the sensor will get a lot less light and you will need to try and even out the settings by changing the ISO an Shutter speed.

ISO The ISO changes the sensitivity of the sensor meaning it will pick up a lot more light on a higher ISO than on a low ISO, But by using a higher ISO it will add noise to the photograph and will look quite grainy or “Noisy” A low ISO looks a lot better as its not got any noise and is very sharp. But you will need to have a well lit subject.

Shutter Speed The shutter speed effects how long the sensor will be exposed to light. The longer the sensor is exposed, the higher the exposure of the photo will be. But if the Shutter speed is long then the subject will have to be very still unless its used for a blur effect or light trails. The higher the number on the shutter speed the more fractions of a second the shutter opens and closes, exposing light to the sensor. The higher the shutter speed, the less light is exposed.
