|
|
Stops
|
An increment of exposure that either doubles or halves the amount of light in an exposure.
|
|
|
F-stops
|
A numerical representation of the diameter of a lens’s aperture.
|
|
|
Aperture
|
The hole or opening inside a lens that determines the amount of light passing through the lens.
|
|
|
Depth of field
|
Refers to how much of the scene is in focus, both in front of and behind the subject or the point of focus.
|
|
|
Shutter

Shutter speeds
|
Refers to the amount of time the mechanical door ina camera opens and closes to allow light to hit the digital imaging sensor.
|
|
|
ISO: (International Standards Organization)
|
The number that represents an imaging sensor’s sensitivity to light.
|
|
|
1/60
|
Use a tripod if your shutter speed is lower than this.
|
|
|
Shallow DOF
|
f/4.5, selective focus
|
|
|
Wide Depth of Field
|
f/22, everything is in focus
|
|
|
Use to blur a moving object.
|
Slow shutter speed
|
|
|
TV
|
Time value mode - you set the shutter speed, camera sets the aperture.
|
|
|
AV

Setting that enables the camera to capture pictures with more accurate color. Common options include fluorescent light, tungsten light (for typical indoor lighting), cloudy conditions, bright sunlight, and camera flash.
|
|

Digital Noise
|
Random pixels scattered all over the photo which may occur when you take low light photos (such as night photos or indoor dark scenes) or you use very slow shutter speeds or a very high ISO
|
|
|
Metering Modes
|
Determines which part of the frame the camera analyzes to calculate the proper exposure. You can choose Evaluative, Partial, Spot or Center-weighted metering with Canon cameras.
|
|
|
CF card
|
Removable data storage device to which your photographs are stored.
|
|
|
Digital image sensor
|
