Having a good understanding of the digital camera modes is essential to control the exposure in photography. Whether you are a beginner or an advanced amateur, you should know what each camera mode does and when it should be used, under what circumstances.
1) What are Digital Camera Modes?
Digital Camera Modes allow photographers to control the parameters of an exposure, specifically, Shutter Speed, Aperture and ISO. While certain modes can fully automate the camera exposure, there are other modes that let the photographer manually control some or all parameters of the exposure.
Back in the old days, there was no such thing as a camera mode – everything was manual. Photographers had to manually set the aperture, shutter speed and choose the right type of film for their cameras. To evaluate the intensity and the amount of light, they used to carry special light metering devices that measured the light and provided the exposure information, which they would then use in their cameras. In 1938, Kodak introduced a film camera with an integrated light meter and in 1962, a Japanese company called “Topcon” introduced the first SLR camera that measured the light coming through the lens into the camera. What this meant, was that photographers no longer needed to carry special light meters with them – the camera would do it for them. New “Automatic” camera modes started appearing on cameras, which would evaluate the amount of light that passed through the lens and would automatically pick the right exposure parameters to produce a properly-exposed picture.
