Aperture+&+Depth+of+Field

=APERTURE - lens opening, which allows light into the camera.=
 * ==A wide aperture (f/3.5) allows a lot of light into the camera. This is for LOW LIGHT situations.==
 * ==A small aperture (f/27) allows very little light. This is for BRIGHT LIGHT situations==

=DEPTH OF FIELD - area of focus in your photograph.=
 * =With a large depth of field, much of the photograph is in sharp - use a small aperture (like f/27)=
 * =With a small depth of field, very little of the photograph is sharp - use a large aperture (like f/3.5)=
