Photography in Greek is painting with light. The most important aspect and factor in photography is light. Aperture which is basically the size of the hole in the lens; has to do with the amount of light a camera takes in. Its purpose allowing for better focus regardless of the obscuring light or the squint causing dimness. The shutter speed focus on the speed at which the door that lets light in opens and closes. If you’re in a bright setting, you’d want your speed to be greater so that too much light doesn’t go in. Like wise in a darker setting, you’d want to give it time for more light to come in. In definition aperture controls the amount. Shutter speed the time. Ios the sensitivity. The shutter speed for example the faster, the closer and perhaps faster the target of shooting, and the slower the further away and perhaps more called atmosphere. A wide aperture allows for the object of target, close up, to be captured with a blurred background. And a smaller aperture would allow for a photo of a beautiful landscape or a photo requiring further distance and capturing the background. ISO, which is the sensitivity, is messed with less of the three because often the lower settings are preferred for most images. It’s often changed when the desired image quality can’t be achieved solely with the aperture and shutter speed.
