What does ISO mean in pictures?

sensitivity
For digital photography, ISO refers to the sensitivity—the signal gain—of the camera’s sensor. The ISO setting is one of three elements used to control exposure; the other two are f/stop and shutter speed. With film cameras, using a higher ISO film, such as ISO 400 to 1000, often resulted in noticeable grain.

What does ISO do to a photo?

In very basic terms, ISO is simply 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.

Why would you use a high ISO?

What is aperture on canon?

Aperture is an adjustable opening inside your lens that allows light to pass through to the imaging sensor in the camera body. Conversely, a smaller aperture, or smaller pupil size, is helpful when taking in bright, sunny conditions, where less light is needed to properly expose a scene.

Why is ISO so important in photography?

ISO is an important parameter that determines how bright your image will be. It’s helpful because it gives photographers an extra option to manipulate their exposures .
