Shallow depth of field & a large depth of field and panning images.

What is depth of field?

A camera can only focus its lens at a single point, but there will be an area that stretches in front of and behind this focus point that still appears sharp.

This zone is known as the depth of field. It’s not a fixed distance, it changes in size and can be described as either shallow where only a narrow zone appears sharp or deep where more of the picture appears sharp.


Depth of field 

refers to the range of distance that appears acceptably sharp. It varies depending on camera type, aperture and focusing distance, although print size and viewing distance can also influence our perception of depth of field.
