Depth of Field Pt.4

In your own words, what are the three key factors in determining depth of field for your shot? Explain in detail how each of these three factors affect the depth of field.

1. Aperture

By opening the iris wider, a shallower depth of field can be achieved. On the other hand, a deeper depth of field can be accomplished through a smaller aperture. 

2. Distance from Subject

The closer the subject is to the sensor, the shallower depth of field. Vice Versa, if the subject is further away from the sensor, the deeper the depth of field. Placing the camera away from the subject allows the light to spread apart slower, capturing more distance in focus.

3. Focal Length

Focal length is determined by the distance between the sensor and the lens. With a larger focal length, a shallower depth of field an be obtained, while a smaller focal length can create a deeper depth of field.
