How many people have gone on a photography holiday and come back with photographs they are not happy with? Often this can be a result of poor exposure. This article summarizes a few tips on achieving the correct exposure, particularly for those who like travel and often go on photography holidays or photography courses.

A picture can say a thousand words. To click a beautiful picture you need a good quality camera that suits your requirements. You must also know how a camera works and how to operate it to use it to the best of its capability. In photography, exposure is a vital element. Exposure in photography can be best described as the amount of light which can be allowed on a photographic film while taking a photograph. In simple terms it can be said to be one single shutter cycle. Exposure is controlled by two main factors, the exposure time and the exposure compensation which collectively determines the amount of light falling onto the photographic plate in side the camera.

The Exposure Time: In a camera the exposure time is controlled by the shutter speed and the lens aperture (device to control the amount of admitted light). The exposure can be determined by length of the time as well as the level of illumination allowed on the photographic medium. The exposure of a photograph also depends on the sensitiveness of the medium in use.

The Exposure Compensation: Generally all kinds of camera have an exposure compensation feature. During the day time under sunny or bright condition, the aperture should be less so as to allow less amount of light to fall on the photographic plate. This is done so that the image or photograph does not get burn due to over exposure. On the other hand on a cloudy day the aperture should be increased in order to allow greater illumination on the photographic plate so that the photograph does not get under exposure.

A Photography course or photography holiday teaches all the aspects of photography in details. Some important features of photograph exposure can be illustrated a bit more.

Overexposed: A photograph is overexposed when too much of light passes through lens aperture and falls on the photographic film. Too much of light burns the photograph and the result is a whitish picture. This often happens if the lens aperture is not properly adjusted on a bright and sunny day.

Underexposed: Generally on a cloudy day or in a place with insufficient illumination, the chances are that if not adjusted, the film will remain underexposed. This will result in a picture darker than it is.

Manual Exposure: As the name suggests, in a manual mode the photographer manually adjusts the shutter speed and the lens aperture to accomplish the preferred exposure.

Automatic Exposure: Many cameras nowadays have automatic exposure mode. An automatic exposure mode automatically adjusts the exposure setting to match with the mid tone of the photograph.
