Photo of a Guitar shows depth of field

Depth of field is an old term. It can be described as being the range of distances in an image where the image comes into focus to the distance where the image goes out of focus. There are three criteria for depth of field: Lens focal length, Aperture / Lens Opening, and the distance between the camera and subject. We will examine them individually, but keep in mind that their effects are cumulative.

Regardless of how many lenses you have, pick one, and then pick a focal length on the lens. If the lens is a prime, like a 50mm, this is easy. If it’s a zoom, pick a focal length somewhere in the zoom range and, using a piece of tape, prevent the zoom ring from moving. You now have a single focal length. The challenge is to find ways to construct your composition, your subject placement and your framing.

One of the functions that all image makers really seem to like is the ability to apply a “look” to their images. This can be as simplistic as using Instagram filters and as rich as taking a powerful, well edited image and making it look like it was shot on classic film.

As creatives, we have many options available to us to help deliver on our vision.  One of the three primary elements that go into a photograph is our selection of aperture. What Is Aperture Anyway? As much of the exposure process is automated these days, there can be some confusion about how aperture works and how it can affect your image. By definition, an aperture is an opening.  For our purposes we are measuring the opening in a lens that light passes through.   By varying the size of the opening, […]
