Aperture Shutter Speed and ISO

When we use DSLR Camera on manual. We have to consider three aspects of Camera in mind which are following:

• Aperture
• Shutter
• ISO

Aperture

In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane.

Shutter

In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a light-sensitive electronic sensor to light in order to capture a permanent image of a scene.

ISO

ISO stands for International Organization for Standardization. Its determines the light sensitivity of CMOS sensor.
