F-Stop, Aperture and Depth of field
Aperture
Aperture is the size of the opening of the lens when a
picture is taken. Whe you hit the shutter release button on the camera a hole
opens up that allows the image sensor to catch a glimpse of the scene you are
wanting to capture. The aperture that you set affects the size of the hole.
The smaller the hole the less light gets in (shallow depth
of field making the image in the foreground in focus and the background fuzzy).
The larger the hole more light gets in (large depth of
field means most of your image is in focus wether its close to the camera or far
away) .
Aperture is measured in F Stops - f/2.8,
f/4, f/5.6,f/8,f/2
DEPTH OF FIELD/ APERTURE EXAMPLE SHOTS
Large Depth of field = higher f stop number = small aperture
Shallow depth of
field = F Stop 5 = large aperture
