Fundamental Lessons On Camera Exposure

anopenletterAperture, 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.

Comprehending The Exposure Triangle To Ace Photography

Ace is HighThe exposure triangle has three vital elements that include ISO speed, shutter speed and aperture. All the latest versions of DSLR contain the Auto modes. These automatic modes instantly pick up the right shutter and ISO speed along with aperture to bring out good exposure. The camera arrives at the right combination of these three elements based on the availability of light. But these features can also be manually controlled for bringing out more vivid pictures. ISO speed is measured through numbers. A smaller number such as 100 emphasizes lower sensitivity to light whereas numbers such as 800, 1600 represents greater sensitivity.

Shutter speed is characteristically measured in terms of fractions of a second. By maintaining a slow shutter speed, more light enters into the camera sensor. A slow shutter speed is often used for shooting in the late evenings and night. A fast shutter speed helps in freezing the movement. Most common examples of shutter speeds include 1/15, 1/30, 1/60 and 1/125 of a second. While considering the aperture, it is measured in f numbers. The focal ratio or the f numbers such as f/1.4, f/2.0, f/2.8 indicate the depth of the field. Smaller aperture contributes to larger depth and larger aperture contributes to a smaller depth. Understanding these basic elements augments your photographing experience.
