Explanation

Aperture is an hole or an opening in a camera through which the light enters. The aperture and the focal area are directly proportional to each other. With the increase in aperture, the focal area also increases. The aperture stop is a significant element in most of the optical designs. White balance is a process of removing the unrealistic coloring casts. The objects which appear white in real are provided white in the photograph. The white balance takes in account the color temperature of the light.
