Controlling Your Depth of Field

1. What are the different factors that you can use to control depth of field that this video mentions? What is one of the primary ways to control depth of field?

The aperture, the distance between the subject and the lens, and the focal length of the lens all play a role in changing the depth of field. The most accessible way to alter the depth of field is to change the aperture. Once the desired depth of field is adjusted using the aperture, other setting must be adjusted accordingly. This includes the light level, ND filters, ISO, and the shutter speed. Changing the focal length of your length can also alter the depth of field. For prime lenses, this can only be done by switching out lenses. However for zoom lenses, there is the option to change the focal length by zooming in. It is important to regard that in a zoomed in shot, space will appear compressed. If a subject is closer to the lens, a shallower depth of field can be accomplished. This may be difficult because the composition of the shot must be manipulated in order to create this look.
