Technique Page - Depth of Field

Definition: depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.
How do you do it?
Part of my transition work from AS to A2 saw me experimenting with a technique called depth of field. The technique can be split into two different styles: minimum depth of field and maximum depth of field. Here's how they can both be done:

Minimum depth of field -  this is when the foreground is sharp and in-focus, but the background is completely blurry.

Three things can be changed to create this effect:

• Get close to the subject
• Make the aperture bigger (a small number)
• Use a larger zoom (300mm on the college cameras)

Maximum depth of field - this is when the entire picture is completely sharp and in-focus.

Three things can be changed to create this effect:

• Get far away from the subject
• Make the aperture smaller (a big number)
• Use a smaller zoom (28mm on the college cameras)

What does it look like?
