Basic Camera Controls
If you're new to the field of photography these three terms are very important and easy to learn.
there are three camera settings that you can control: aperture, shutter speed, and ISO.
Aperture: is the aperture in the camera’s lens, and its size determines how much light is allowed in. The higher the number, the smaller the hole and less light get in.
f/16 is very small and lets in very little light
f/1.4 is much bigger and lets in a lot of light
Shutter Speed: Controls how long the shutter stays open to let light in. The number indicates seconds or fractions of seconds. A shutter speed of 1 means that it’s going to open for a full second, which is slow. A shutter speed of 1/250 is quick and freezes the action.
The aperture and shutter speed work together, a faster shutter speed often needs a wider aperture to let more light in, while a slow shutter speed needs the opposite.
ISO: The ISO controls the camera’s sensitivity to light. If the ISO number is high, the camera works harder to gather the available light. On a sunny day, the camera doesn’t have to work that hard, so an ISO 100 is sufficient. But at night and ISO 800 or much higher allows the camera to collect more light.
These three elements work together and they can help you achieve different types of photography depending on what you want to transmit. A good way of learning is by doing, and going out to take photographs to better understand the use of each element.
