What is f-stop and ISO?
Two controls affect the amount of light that comes into the camera and strikes the image sensor – aperture and shutter speed. The ISO affects how much light is needed to produce a correct exposure. The aperture settings are commonly referred to as f-stops and have a specific numerical sequence, such as F5. 6, F7.
What are the ISO stops?
ISO speed describes how sensitive your camera’s sensor is to the light that hits it. As with shutter speed, doubling the ISO number gives an increase of 1 stop, while halving gives it a decrease of 1 stop. For example, switching from ISO 100 to ISO 200 doubles the sensor’s sensitivity, producing a 1 stop increase.
What is ISO f-stop and shutter speed?
A “stop” is the unit of measurement for the amount of light that makes up the exposure determined by the shutter speed, ISO, and aperture. For example, you can increase your exposure by one stop by increasing your ISO from 100 to 200, your shutter speed from 1/60th to 1/30th, or aperture from 11 to 8.
What is ISO vs aperture?
ISO is how sensitive your sensor is to light. Higher ISOs allow a sensor to absorb more light—but they also introduce more noise to the photo. Aperture is a measure of the amount of light allowed to hit an image sensor. The wider the aperture, the shallower the depth of field, and the more light that comes in.
What does the F-Stop do on a camera?
F-stop is the term used to denote aperture measurements on your camera. The aperture controls the amount of light that enters the camera lens, and it’s measured in f-stops.
What does F 2.8 mean in photography?
Here’s the aperture scale. Each step down lets in half as much light: f/1.4 (very large opening of your aperture blades, lets in a lot of light) f/2.0 (lets in half as much light as f/1.4) f/2.8 (lets in half as much light as f/2.0)

What are the full f stops?
Full stop numbers are f/1.8, f/2.8, f/4/0, f/5.6, f/8.0, f/11, f/16, f/22, f/32, f/64. They are called “full stops” because when you change the aperture from f/11 to f/8.0 that doubles the amount of light. Every time you go up one stop f/5.6 -> f/4.0, you double the amount of light that gets through the lens.
What does a high F-stop indicate?
The lower the f/stop—the larger the opening in the lens—the less depth of field—the blurrier the background. The higher the f/stop—the smaller the opening in the lens—the greater the depth of field—the sharper the background.
