Canon EOS 40D: Depth of Field

Video Transcript

"All right, the final creative mode that we're going to talk about is the automatic depth of field mode and right now we're in manual mode. But what I'm going to do is just turn the mode dial over here on the top of the camera, to line up the A dash D-E-P setting on that dial with our white line on the top of the camera. And that will set our camera to automatic depth of field mode. What this mode does is, let's say that you had three people that you wanted to take a picture, and those people might be staggered at different distances from the camera, but in this mode, if each of the, one of the focusing points on your camera sensor were placed on each of those three persons in the shot, and you, when you press the shutter button and those focus points are activated in autofocus mode, the camera will automatically adjust to keep all of those people in focus, in the depth of field. So that all of your shot will be, will be in focus. The only thing to consider in this mode, or one of the main things to consider, is you may need to change the ISO setting more than anything else. If you press down the shutter speed and either your aperture or your shutter setting start to blink, then you may need to increase or your decrease your ISO speed depending upon the exposure meter. So, in this mode, the really, the benefit or the advantage to this mode is that all of your subjects will be in focus automatically."
