Figure 5: Sunset Graduated Filter

For those photographers who shoot JPEGs only and are not interested in a lot of post-processing work, a creative filter system is ideal for more creativity in-camera. Cokin’s filter system, for example, is an easy-to-use, flexible option that offers a variety of creative opportunities.

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.
