- Define the meaning of aperture, shutter speed, ISO, and depth of field (DOF)
Aperture is referred to the lens diaphragm opening inside a photographic lens. In a simple word, aperture can be consider as the hole within a lens, which the light enter the camera body. Every camera that we know today is designed like human eyes. The cornea in our eyes is like the front element of a lens – it gathers all external light, then bends it and passes it to the iris.
Shutter speed, also known as “exposure time”. Shutter speed can be defined as length of time a camera shutter is open to expose the light enter the camera sensor. Shutter speed is a measurement of the time the shutter is open, it is shown in seconds or fractions of a second: 1 s, 1/2 s, 1/4 s, 1/250 s, 1/ 500 s, and others.
ISO can be defined as the level of sensitivity of our camera to available light. The lower the ISO number, the less sensitive it is to the light, while the higher of ISO number, it will increases the sensitivity of our camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”. It is the most important and most expensive part of a camera and it is responsible for gathering light and transforming it into an image
Depth of Field (DOF) can be defined as the area that stretches in front of and behind the focus point that are still sharp.

|Camera angles affect how we perceive it. The more extreme the angle, the more symbolic and heavily-loaded the shot.||Whereas camera shot direct who and what we see.|
