Photographer's Tip - Depth of Field

Recommended Posts

The photography term 'Depth of Field' refers to how much of the photograph is in focus. Depth of field is achieved by using the aperture (f-stop, the opening in the lenses that lets the light hit the film plane/sensor to create the photo). The smaller the aperture the more depth of field. The depth of  field in the photo below is shallow or narrow, only a little of the flower (Cherokee Sunset dogwood)  is truly in sharp focus.

The photo below has deeper depth of field, more of the flower is in focus. When taking close-ups like this the depth of field is going to be narrow even at the smallest aperture opening.

Here's a part of a handout that I have for the Photography classes I give that helps explain f-stop.
