Photographer's Note

A friend, who is starting photography, was browsing through Trekearth the other day. She was looking through the photos to learn from it as well as the comments given to the photo.

She called, asking for the meaning of DOF. It was mentioned in some comments and wondered what it was. As I didn't have time enough to explain, I thought I would give an example. Just in case she comes browsing my gallery this weekend.

DOF stands for Depth Of Field. It is a depth or range, where available objects within that range, is sharp. Anything else outside this range, is blur.Even if there are objects closer to the lens than what is focused.

The row of five droplets in the middle, on the waterlily leave is in focus, therefore sharp. You could see sharp details too, a little bit in front and behind it even though the lens is focused mainly, on the middle droplet. But those droplets closer and farther than the focused droplets, is blur. This photo has short DOF, as seen in all macro/closeup photography.

Long DOF is when the range or depth is longer. Especially in landscape photography, when anything in front of the camera to the horizon is relatively sharp. Or when shooting subject in bright light at F/8 or higher.
