#1. The three settings that determine camera exposure are aperture, ISO, and shutter speed. This is also known as the “exposure triangle”.
#2.
- Aperture: controls the area over which light can enter your camera.
- ISO: controls the sensitivity of your camera’s sensor to a given amount of light.
- Shutter Speed: controls the duration of the exposure.
#3.
- Aperture: It helps to focus on a certain areas depth of field. For example, your aperture setting would increase when you are taking a picture of a landscape, you want to take the picture in a way that nothing gets blurred out because detail is most important. However, when you are taking a picture of a single leaf on a tree you would only focus on that leaf and everything else would be blurred out because the leaf is the focal point.
- Shutter Speed: In slow shutter speed, anything that moves will blur but anything stationary in the image will stay in focus. In a fast shutter speed, all the movement in the photo is frozen for a brief moment. For example, you would use the fast shutter speed to capture action.
- ISO Speed: A higher ISO Speed means your camera sensor can capture images in low light environments without having to use a flash but it adds grains or image noise to the pictures. A photo with a low ISO Speed is more desirable then a photo with a high ISO Speed because it is clearer.
