Photography — Dissected
Aperature is how much light is allowed into a lens. Similar to the way an iris works in the human eye, the lens on a camera will also dialiate when exposed to darker environments and shrink when exposed to light. By making the lens larger in darker areas, the camera can allow more light into the photograph to add balance and vice versa.
Shutter speed controls the quality of photos when the subject is in motion. By using a fast shutter speed, a photographer would be able to capture its subject in motion with crisp clarity. Using a slower shutter speed would result in a blurry photo when trying to focus on a moving subject. Shutter speed revolves around motion and the level of activity with in a photo. It is the length of time given to the lens to capture a photo.
ISO captures the noise of a photo. This element of photography can make a photo brighter or darker in different types of lighting. For example, ISO allowed me to take this photo at night. If the ISO is too high, it can cause a photo to look grainy. Finding the right ISO for the specific lighting you’re in is essential for creating a clear photo.
Depth of Field regards how much of the photo is in focus. It is the distance between the subject versus the background. DOF is created by adjusting the aperature. The larger the aperature, the larger DOF and vice versa. Depth of Field is controlled by focal length, aperature, and the distance from the subject.
Dynamic Range is measures the different light intensities within a photo. When taking a photo with lots of light, the dynamic range could be more intense, such as the photo I have taken above; whereas in dimmer environments, the range could be less intense. The higher the range, the more shadows there are.
