The images below or shot on a crop sensor camera with a crop fact of 1.6x.

Or you can think of it as how zoomed-in your lens is.
Creating a Blurred Background in CameraĬreating a blurred background by selecting the right focal length for your lens and using the right camera settings is called creating a shallow depth of field.įocal Length: Focal length refers the length from the optical center of a lens from the focal plane.
