Aperture VS Shutter Priority Mode – Which one is required when
Aperture VS Shutter Priority Mode. There are basically three ways to carry auto exposure in camera. Auto exposure is different from manual mode where the photographer has to set both, aperture as well as shutter speed in a camera. The three different ways to do so – aperture priority mode, shutter priority mode and program mode. In aperture priority mode, you have to select a particular aperture value and for that value camera does shutter speed selection to match it. In shutter priority mode you decide the shutter speed and according camera selects matching aperture for that. In program mode you don’t have to do anything, camera selects both, aperture as well as shutter speed.
Aperture VS Shutter Priority Mode – Depth of Field
Whenever you want to have control over depth of field, aperture priority mode is to be opted. Aperture priority mode is used in a situation where you require all the objects in the photograph distinct and clear for example landscape photography. In such case narrow aperture is used while shutter speed most of the time is not that important. Aperture priority mode is also useful in portrait photography where wide aperture settings make background out of focus and prevents distraction to main object in photograph. The main impact of aperture on images is depth of field. Usually aperture priority mode is used when you have to control depth of field. For shallow depth of field you have to select large aperture and for greater depth of speed you opt for small aperture.
Aperture VS Shutter Priority Mode – Capturing moving objects
In shutter priority mode, you have to decide the shutter speed and allow the camera to decide on the value of aperture. The different shutter speeds have impact on capturing moving objects in your photographs. Thus you can shift to shutter priority mode in order to get better control on taking snapshots of the moving object. In case you want to freeze a moving object without any motion blur, you will have to select faster speed and accordingly camera decides appropriate aperture automatically depending on the amount of light to be allowed. However in case you want some motion blur to show how fast an object is moving, slower shutter speed to be selected and accordingly camera selects the aperture.
Aperture VS Shutter Priority Mode – Know your circumstances
Shutter as well as Aperture Priority modes offer you more control over the photographs but that actually requires a bit of practice for better results. To master the art it is recommended to take photographs of same subject for different settings. Experimenting with your camera for different settings is the best way to get the feel of how camera responds to various settings in aperture and shutter speed. In Aperture Priority mode better take shots for larger aperture and also for lower aperture to judge the results. Similarly check the results in Shutter Priority Mode for different settings. Initially the snaps taken will not have desired results but keep in mind to master these settings is not an overnight job. It requires lot of practice and continuous learning. But believe it once you have understanding of these controls your artistic skills will have far reaching impact.
In the next part the third option called program mode will be explain and comparative study of various modes to have better clarity on the various modes will be explained.
