APPENDIX

Aperture: Aperture refers to the lens diaphragm opening inside a

photographic lens. The size of the diaphragm opening in a

camera lens regulates the amount of light that passes through

and onto the sensor inside the camera the moment the shutter

curtain in camera opens during an exposure process.

Digital zoom: Digital zoom crops the image to a smaller size, and then

enlarges the cropped portion to fill the frame again. Digital

zoom results in a significant loss of quality.

Effective pixels: Effective pixels are the number of pixels actually used in the

image after the edge pixels have been dropped.

Exposure compensation: Exposure compensation is used to alter exposure from the

value selected by the camera, making photographs brighter or

darker.

Image Sensor: An image sensor is a device that converts an optical image into

an electrical signal.

ISO speed: The ISO (International Organization for Standardization) speed

is a measure of the sensitivity of the camera to the incoming

light. A lower ISO speed is almost always desirable, since

higher ISO speeds dramatically increase image noise.

Metering: Metering is used to measure the brightness of a subject. The

camera adjusts shutter speed and aperture for optimal

exposure according to the brightness of the subject which is

measured using the camera’s built in metering sensor.

Optical zoom: In optical zoom, the lens changes focal length and

magnification as it is zoomed. Image quality stays high

throughout the zoom range.

Pixel: A pixel (picture element) is a physical point in a raster image,

or the smallest addressable element in a display device.

Pixel area: Pixel area affects how much light per pixel can be gathered.

The larger it is the more light can be collected by a single pixel.

Pixel density: Pixel density defines how many million pixels fit or would fit in

one square cm of the sensor.

Pixel pitch: Pixel pitch is the distance from the center of one pixel to the

center of the next.

Resolution: Resolution is the number of pixels per inch. It describes the

amount of detail the camera can capture.

Shutter: A shutter is a device that allows light to pass for a determined

period of time, for the purpose of exposing photographic film

or a light-sensitive electronic sensor to light to capture a

permanent image of a scene.

Shutter speed: Shutter speed is the effective length of time a camera's shutter

is open.

Total pixels: Total pixels count every pixel on the sensor surface including

the edge pixels.

Viewfinder: The viewfinder shows what the lens will project on the sensor

via a mirror and a prism and therefore has no parallax error.

White balance: White balance is the process of removing unrealistic color

casts, so that objects which appear white in person are

rendered white in the photo.
