Aperture Priority Mode

DSLRs have become a lot more popular these days thanks to their superior image quality and reduced prices in recent times. Unlike earlier times, when DSLRs were only used by professional photographers, people nowadays find it extremely easy to operate these cameras and master the art of photography. The major reason behind this is the automatically controlled system which come installed in latest generation DSLRs which can control everything from aperture, sensitivity, exposure etc. With the automatic system in place, even a amateur photographer can take very good shots despite having only basic knowledge of the camera.

Apart from the fully automatic mode, DSLR come equipped with many programmable modes such as Aperture priority mode, shutter priority mode etc. While shutter priority is suitable for high speed photography, it is the aperture priority mode that is mostly used for creating very artistic photography effects.

So before explaining What is “Aperture-Priority” mode on your DSLR camera, I would like to first introduce you to the three basic factors in every DSLR known as the exposure triangle. Aperture, Shutter speed and ISO constitute the exposure triangle and by adjusting these three setting you can control the amount of light being captured in the camera. Mastering the exposure triangle will give you immense opportunity to play with light and shoot pictures exactly the way you want.

Aperture setting determines the amount by which the lens opens and allows light to enter the camera sensor. But apart from this basic feature, aperture is also responsible for a very important effect in photography called Depth of field. Having a wide aperture gives you very shallow depth of field and you can click very artistic images by blurring out the background from you subject, this effect is particularly used in portrait photography, but at the same time you have to control the shutter speed and ISO setting so as to compensate for the wide aperture and to prevent your image from getting over exposed.

So you have to control all three aspects on the DSLR to get a perfect image and you should know how to balance these settings. But most of the time, this process is very tedious and time consuming. Many amateur photographers find it difficult to find a perfect balance between these three settings and tend to over expose or under expose their images.

To solve this problem and help budding photographers, DSLRs come equipped with a setting called Aperture priority mode. This is an automated mode which allows the user to adjust the lens aperture according to his/her requirement. All the other setting are compensated by the camera processor which finds the best setting suitable in that environment and sets ISO and shutter speed according to the selected aperture setting. This is really helpful as the photographer can now focus on capturing the frame perfectly without worrying about the auxiliary camera setting.
For instance, if you want a nice bokeh effect, you jus have to set your camera to aperture priority mode, select the widest aperture and click. By analysing the environment, the camera will compensate for the shutter speed.
These automated modes help in clicking photographs quickly which is very helpful if you are covering an event like wedding, reception etc.

While professional photographers may still stick to complete manual mode as it provides complete control over the camera, the Aperture priority mode is a very good option for photographers that want to capture good images without getting too deep into the details.
