Aperture, ISO and shutter speed are the three main elements that contribute to the light exposure in your pictures. They determine the light or dark appearance of your picture. Understanding these three basic elements is an imperative part to master photography. Never under or overexpose your pictures. Make sure to set the aperture, shutter and ISO speed in line with the attributes of your subject. Lighting is also a vital element that influences the quality of your pictures. The role of an aperture is to control the area through which light enters the camera. The duration of light exposure is controlled by shutter speed.

ISO speed is used to handle the camera’s sensitivity towards a given volume of light. Hence, aperture, shutter and ISO speed can be used in different permutation and combinations. Make sure to remember that each setting influences the other as well as the picture quality. Improper shutter speed can result in blurred images and inappropriate aperture disturbs the depth of the picture. Shutter speed if used properly can freeze or exaggerate the appearance of motion. Arriving at a right shutter speed brings out a desirable sharpness in the image. The aperture and ISO speed can be aligned analogous to shutter speed to augment the picture quality.
