More on Aperture: Deep Depth of Field

We refer to a picture as having "Deep Depth of Field" when everything in the picture is in focus, from the foreground to the background. If only one element of the picture is in focus, such as a portrait, it is said to have "Shallow Depth of Field." Good subjects for Deep Depth of Field are landscapes and cityscapes... Ansel Adams is a master of deep depth of field (click here to see some of his pictures).

To create Deep depth of field you need to use a small aperture, such as f/11, f/16, or f/22. As the aperture gets smaller, the shutter speed needed for a correct exposure gets longer, so you may want to borrow a tripod or brace your camera against a rock or on a bench to keep it steady.

This photo was taken along Sligo Creek during the winter, probably with a tripod. Notice how everything is pretty much in focus from the foreground to deep down the stream.

Please add your comments to this blog, suggesting to your classmates what it is you might photograph as your deep depth of field subjects.

Your print is due by close of business Thursday, October 19.
