Put simply, ISO is a camera setting that will brighten or darken the photo.

Shutter speed is the length of time the image sensor in your camera is exposed to light.

Aperture relates to the opening of your lens’ diaphragm (the little hexagonal opening), and how much light is actually passing through.

Editing can include things such as adjusting the color, cropping to a different size, removing an object from the image, and much more.
