Digital Camera Reviews

If you're wondering about camera basics, this will help with depth of field.

Next we move on to depth of field. This is actually a really simple term that just refers to how much of the image area is in focus. Pictures that have everything in focus are said to have a high depth of field, where pictures that have a small area in focus, and a lot of blurry back/foreground are said to have a narrow depth of field. The length (zoom) of the lens and the aperture are two of the biggest factors that determine the depth of field. With out getting too teched out, if you understand how a pinhole camera works, you will understand why a higher f stop (thus a smaller hole) creates a greater depth of field.
