Using Depth of Field for Sporting Events

Posted on by learndigitalphotography in Blog, Digital Photography, Digital Photography Basics, Digital Photography Tips

Most all dramatic sports photos are shot with the lens wide open or one stop from wide open. This is done for two reasons. First you need all the shutter speed you can get, which means shooting wide open, but just as important, it has to do with isolating the subject. As the aperture on a lens opens up, less and less of the photo is in focus. The longer the lens, the more dramatic the change. The larger the distance between the subject and the background the more out of focus the background will come. If you use a long lens and a fast aperture, then your subject will stand out and the background elements will have less impact on your photo.

Reducing background noise is an important goal in many photographs, sports action or not. In studio or landscape settings, you have time to control the elements that make up the picture. Action photography is a "grab it now" type of shooting and you live with the background that is there. If you open up the lens to its maximum, you will find your subjects standing out and becoming memorable.

When you are shooting sports, in particular football and soccer, keep in mind that plays shot on the far side of the field are closer to the background than shots on the near side of the field. Thus if you are shooting a soccer player moving the ball down field and the player passes in front of the bench when you snap the shot, you will have a very distracting background. It may be hard to separate the player and ball from the background noise. Fences, signs, poles, bleachers, stands, and people on the far sideline can really mess up a good shot. Even though you might be shooting wide open, the background will be too prominent in these shots. Should they be avoided? If you have better shots, don’t use it. However, it may be your best shot. Shoot it, just be aware that distracting backgrounds are more problematic on shots on the far side of the field.
