Digital Single Lens Reflex
'Reflex' refers to the reflection of light from the mirror and into the pentaprism
The opening through which light enters the camera
The diameter of the aperture in relation to the depth of the image and the amount of light entering the camera
The device that gathers light into the camera, composed of a series of glass plates
Takes the light entering the lens and bounces it 90 degrees into the pentaprism. When the shutter button is pressed, the mirror swings down so the light can be collected by the image sensor under the eye-piece
A fived-sided shape that collects the light from the reflex mirror and transmits it to the viewfinder
Digital Photography Summary
A small aperture will result in a large f-stop number
Shorter Shutter Speed= Less time to capture light
The longer the lens, the faster the shutter speed needs to be
Depth of field:
how much of the background is in focus
Ex. f/5.6- shallow depth
f/32 wide depth
Charge-Coupled Device & ISO
coverts light in a digital camera into electronic data
The quality of an image depends on the
sensor of CCD.This is usually measured in
The resolution of an image determines the clarity
The higher amount of megapixels, the higher the resolution of the image

(International Standards Organization)
measures the light sensitivity of the image sensor
The lower the ISO number, the less sensitive the sensor is to light
This will result in a finer grain
Has a short focal length, yet provide wider shot of a scene compared to a standard lens. Good for landscape portraits
Long focal length and strong magnification. Used for capturing images far from the position of the camera
Used for photographing subjects at a close range i.e. insects, flowers. Provides sharpness close-up
Has one focal length, yet a very wide aperture, and therefore, high shutter speeds
High quality lens
