What Is Depth of Field?

Bokeh is essentially the character of the outer focus areas in the background of a photograph. Different lenses and actually different appateurs in different lighting conditions, give a different look to the bokeh. Depth of field depth is how much is sharp in front of and behind the subject because even though you focus on the subject it will be absolutely sharp. If you select an aperture with a big number like 16, you get a big depth of field, a small number four or 2.8 and you have a small depth of field. It's very common on social media photos you see them on Instagram and Facebook etc.
