Portrait and Depth and Field? I have a question about Portrait and Depth and Field pictures. I thought a picture with a blurred background and sharp subject was a portrait and a picture with a sharp background to foreground was DOF. DOF pictures are easy to determine “depth” as a distance of measurement and portrait’s are hard to see depth cause they have no depth. I have noticed that most are confused on each type of picture. My question is why? Please take no affiance, it is just a question you all are great.

Depth of field is simply the distance in-front-of and the distance in-back-of the subject you're photographing that is in focus. "depth of field" is how much 'depth' does my 'field of in-focus' have with the subject being in between there somewhere. For instance, if you had an aperture setting of 5.6 and your subject was 10 feet from you, you might have flowers in focus about 1-2 feet in front of the subject and maybe some bushes in focus about 4-6 feet in back of the subject. (don't take my distances as true, just an example) SO, the depth of field (what's in focus) is roughly 2 feet in front of and 6 feet in back of your subject. NOW, with an aperture setting of 16, your DOF is greatly increased. Maybe 8 feet in front of and 20 feet in back of the subject, again subject at 10 feet from you. A portrait doesn't have to have a blurred background. It may be preferred, in many cases, so the background doesn't distract from the main subject but the portrait could be an "environmental" portrait that shows the subject in his/her surroundings (workplace, hobby interest, home, etc). BUT that's getting into another area.
