We have all seen beautiful photos where the object is perfectly focused while the background is blurred. Such a photo can be very dramatic and might seem to be hard to shoot. In this article we will give you a few tips on how to shoot blurry background photos that will impress your friends and family. You will also understand what Depth of Field is and how to control it.
How do you control the depth of field? After all there is no “depth of field" menu in the camera (wouldn’t that be nice…). Depth of field is an optical figure that is influenced by a few factors:
After understanding the theory it is best to go to the field an experiment. You will get a sense of how your photo will look like and how blurry the background will be after playing with different lenses, different apertures and different distances from your object. If you own zoom lenses start with taking photos of a relatively close object while using your zoom lenses. You will find out that it is extremely easy to get a blurry background photo using this method even without setting the aperture. Once you feel comfortable with that setup start changing the aperture and also change to your normal 18mm-55mm or similar lenses.
Most cameras allow to manually change the aperture by putting the camera in “A" mode – while you are changing the aperture the camera will automatically set the shutter speed accordingly. Some cameras allow you to manually set both aperture and shutter speed.
In conclusion shooting dramatic blurry background photos is easy with some minimal understanding of depth of field and some experimenting.
