APOGEE PHOTO MAGAZINE: Understanding Depth of Field by Jim Altengarten

APOGEE PHOTO MAGAZINE: Understanding Depth of Field by Jim Altengarten: "In landscape photography, depth-of-field is a critical component of every image. Some photos require minimum depth-of-field to place more emphasis on a single element of the scene. Classic landscape shots have extensive depth-of-field to provide front-to-back sharpness. Since depth-of-field is so important to landscape images, we’ll address several questions, such as what is it, how do I control it, how do I know if I have enough, and can I estimate depth-of-field when in doubt?"
