Shallow depth of field is used in photography to focus on the subject and blur the background so as to remove any distractions. However, while taking portrait pictures, this often results in blurred portions on the subject itself. Even otherwise, sometimes, you may want to capture the background as well. So, how do you control the depth of field and get rid of problems inadvertently created by shallow depth of field? Here are some tips.
This mode supports clicking the portrait images and set the aperture according to the image. But, in some cases, this also loses the control over the shallow depth field.
Aperture priority mode
Aperture is the size of opening in the lens. Have you ever explored or seen different modes in the cameras? If you have seen, then you should have also observed the aperture priority mode in the camera.
Aperture mode is a way to control the depth of field in the images and minimize the distractions in background of the portrait.
As you minimize the aperture, the shallow depth field also gets minimized and blurry images are avoided. Take different shots with different aperture modes and you can understand how aperture controls the distractions in the portraits. The aperture should be set into small i.e. the aperture mode on the camera must be set in larger number.
When you are clicking a portrait image, why do you need large background? Your portrait photo should have maximum portion of the subject and minimum portion of background.
Background is just nominal and sometimes you can even ignore it, but in some cases the background is very important and necessary. So, why don’t you stand at a fairly long distance where the background automatically goes out of screen? By doing this, you are covering the background and also minimizing the shallow depth field.
Many use different lenses to improve the shallow depth of field. Use lens with different aperture and different focal lengths.
The main use of these zoom lenses is the picture frame will be completely filled with the subjects without the scope of background shallow depth of field. The more the aperture and focal length in zoom lenses, the more blurry will be background.
This also improves and supports smaller aperture and increase the sensitivity of the images. But by doing this, you can increase the noise and pixilation in the images, so take care about this aspect.
Lighting your subject properly can minimize the depth of field. You can use an external flash or use any lighting source to compensate the shallow depth of field.
By decreasing the shutter speed, the aperture comes down automatically and compensate for the shallow depth of field correction.
By following these techniques, you can correct the shallow depth of field in the pictures and correct the abruptions in the background.
