Shallow Depth of Field

Depth of field also becomes shallower as you get closer to a subject.
The choice of lens also affects depth of field.
Telephoto or Long focal length lenses create a shallower depth of field.
Wide angle lenses create a deeper depth of field.
When you are choosing how much depth of field you want in your image, you need to consider APERTURE, LENS CHOICE and DISTANCE FROM YOUR SUBJECT
