Depth Of Field

Depth of field. . .


 is the amount of your image before and beyond your focus point that will be in focus.

Low depth of field. . .
    : you can see middle one so clearly.
      but other which is out of focus cannot be seen clearly.






High depth of field. . .
    : you can see all of them clearly.
      it means all of then on focus.
