An opening in a camera lens that lets light in to the sensor.
You pick the aperture (f-stop) and the camera will set the correct shutter speed. Usually represented by "A"
Metering in which all the light in the scene is averaged to select an exposure
The part of the picture that appears behind the main subject
Placement of colors, light and dark areas, or large and small objects in a picture to creat harmony
A file format that records the image without any in camera processing or file compression. Also known as raw
Device used to transfer images from memory cards to a computer
Center weighted metering
TTL metering that trends to meter the light from the center of the potential picture
The pleasing selection and arrangements of subjects within the picture
The tonal range between the brightest and the darkest pixels
Depth of field
Distance between the nearest and farthest objects in sharp focus. Depth of field depends on the f-stop used to take the picture. Using a higher f-stop
A control that slightly increases or decreases the exposure chosen by the cameras exposure meter
The overall brightness and contrast of a photograph, determined by aperture, shutter speed, and ISO
A way of storing image data in a digital file. Popular digital camera formats include camera raw, JPEG and TIFF

The distance from the lends to a point behind the lens where light rays are focused when the lens is set for infinity
Adjustment of the distance setting on a lens to sharply define the subject
The area between the camera and the main subject
A number used to indicate the light passing ability of the lens
What does a higher f-stop mean?
A higher f-stop number = the smaller the light-passing ability of the lens
A lower f-stop number = the larger the light-passing ability of the lens
A graph mapping the distribution of tones in an image; found on cameras and in editing programs
Area of lightest and brightest light
How sensitive the image sensor is to light. Raising ISO= faster shutter speed, smaller apertures or both.
Pieces of optical glass designed to collect and focus rays of light to form a sharp image
Exposure mode that allows you to control aperture, shutter speed and ISO
Storage cards used in digital cameras
Digital equivalent of graininess in film photography
When too much light reaches the light sensor
Moving the camera so that the image of a moving object remains in the same position of the viewfinder as you take a picture
Choosing a lens opening that produces a shallow depth of field. Usually this is done to isolate a subject by causing most other elements in the scene to be blurred
The device in the camera that opens and shuts to allow light into the camera
You pick the shutter speed and the camera picks the right aperature
Metering from a particular area of the image that you have selected
A three legged supporting stand used to hold the camera steady
A condition in which too little light reaches the image sensor
The provision in digital cameras to optimize color balance for a given light source

2. Interesting subject
3. Complementary lighting
