Opening Up Your Aperture… In Photoshop
The definition of depth of field is the Distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Everything outside of the depth of field gets gradually blurrier the closer or farther it is from the camera. Therefore, when you have a shallow depth of field very little is in focus. As always, it’s best to do this sort of thing in camera but it is possible to achieve in Photoshop!
