# Maybe we need to RETHINK how we think about Depth of Field

## It’s really about Magnification

We know some truths about Depth of Field (DOF). We know there are 3 things (actually 4 but the forth is controversial and not all agree and it would only apply if you switch cameras in between shots)

Anyway, there are 3 things that affect Depth of Field

- Aperture
- Distance to Subject
- Focal Length

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
