anteroI go through the basics of ISO, Aperture and Shutter speed in a simple and understandable way. I focused this article for beginners in photography to get more understanding of the different settings that control the intake of light.
Photography is all about how you control the light. These 3 basic settings is the foundation of photography and will help you take better and more impressive shots. In this video Im explaining the terms.
What is ISO?
ISO is basically a camera setting that will brighten or darken a photo. As you increase your ISO number, your photos will grow progressively brighter. For that reason, ISO can help you capture images in darker environments, or be more flexible about your aperture and shutter speed settings.
However, raising your ISO has consequences. A photo taken at too high of an ISO will show a lot of grain, also known as noise, and might not be usable. So, brightening a photo via ISO is always a trade-off. You should only raise your ISO when you are unable to brighten the photo via shutter speed or aperture instead (for example, if using a longer shutter speed would cause your subject to be blurry).
What is Aperture?
Aperture refers to the opening of a lens’s diaphragm through which light passes. It is calibrated in f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16. Lower f/stops give more exposure because they represent the larger apertures, while the higher f/stops give less exposure because they represent smaller apertures. This may seem a little contradictory at first but will become clearer as you take pictures at varying f/stops.
What is shutger speed?
Definition of Shutter Speed : Like its name, its a physical shutter which opens and exposes camera sensor to light, and then closes as per your shutter speed. The length of time that shutter keeps open is called the shutter speed and also sometimes referred to as ‘exposure time’. We generally measures this in seconds. The shutter speed scale is generally half or double of its previous value and gradually it can go as fast as 1/2000 or 1/4000 or slowest can be 30 sec.
