Anyway, there are 3 things that affect Depth of Field

  • Aperture
  • Distance to Subject

We know:

  • The Larger the aperture (lower f/ number),the shallower the Depth of Field
  • The closer we are to our subject, the shallower the Depth of Field
  • The longer the Focal Length, the shallower the Depth of Field

and of course the inverse of all would be true Continue reading »
