The word photography is derived from a French word which in Greek refers to the art of drawing with light. Light is the basic requirement in digital photography. Exposure is the light collected in a photograph through a sensor. Long exposure of photos to light will make them have a washed out effect. Dark photos will be a result of an exposure which is too short. The amount of light exposed to a picture is measured by the light meter which is inbuilt in cameras. The secret of taking great photos lies in learning how to control exposure to light and reliance on the meter is discouraged.
Controls for shutter speed and aperture are found in cameras. A lens is an opening that allows light into a camera and is also known as an aperture. The time that light is exposed to the sensor is known as the shutter speed. The ISO refers to the changing of the sensitivity of the sensor to either raise or lower the light’s speed. Quality of photos is determined by the use of light in photography. Details in photography will be added by the angle of light. Among the uses of light is to create silhouettes, brighten dark backgrounds and show depth. Creative photos can be achieved by adjusting the angle of light to create moonlight and motion effects.
Photographers who want to take portrait photos must have basic skills in capturing them in a still form to get the best results. Genuine digital portrait photography is a must and the shots should be taken spontaneously. Portraits work best with spontaneous poses. To make sure that the subject stands out, the background should be made darker to create emphasis. Black and white photography gives out details that are otherwise ignored. A keen eye transforms even the dullest of images to an amazing photo by creating a composition with points of interest.
