Multiple ways of using Shutter-priority AE mode to create better pictures. The Canon AE-1, introduced in 1976, was the first 35mm SLR camera to feature the Shutter-priority AE mode. It was also the camera to have all its functions controlled by a built-in CPU (Central Processing Unit). Until the Canon AE-1 made its debut, all the other 35mm SLR cameras then used the Aperture-priority AE mode for their automatic exposure control. The Canon AE-1 35mm SLR camera   With the exceptions of the manual-focus Canon AV-1, AL-1, T50 and T60 as well as the T80, EOS 750 and 850 AF models, all the other Canon 35mm SLR cameras introduced after the AE-1 have the Shutter-priority AE as one of the modes offered. The EOS 750 and 850 do not have Shutter-priority AE mode   EOS users can choose Shutter-priority AE mode when it comes to capturing moving subjects. Obviously, you need a fast shutter speed to prevent blurring due to camera shake (when using long lenses) or when you want to freeze the subject in its tracks. Or use slow shutter speeds for capturing the motions. Shutter-priority AE is the best choice for shooting sports, because things happen fast and not all types of sports can be shot at slow shutter speeds. This is particularly so for athletic events like long jump and high jump or the 100, 200 and 400 meters track and field events. Occasionally, you do see examples of these track and field events being shot using slower shutter speeds to give a sense of motion for creative effect. Other sporting events like tennis, baseball, basketball, rugby, swimming and soccer are among those that are shot using high shutter speeds. Sporting events where slower shutter speeds can be used are the Formula One auto racing, motorcycling GPs, marathons, water-skiing, powerboat racing and cycling. Panning technique is used to create a feeling of speed or motion. But how does one know when is the best time to use Shutter-priority AE mode effectively? Basically, there is no rule of when you should use this mode or not at all. It is entirely up to the user. The proven metered manual exposure mode is one of the old ways of selecting the shutter speed and aperture by yourself rather than have the camera do it for you. << Back to Main . 1 . 2 . 3 . 4 .
