The International Colour Consortium, An industry group that has endorsed a standard format for device profile.

An application that enables you to view digital photos. Some browsers also allow you to rename files, convert photos from one file format to another, add text descriptions, and more.

A computer program that enables you to adjust a photo to improve its appearance. With image editing software, you can darken or lighten a photo, rotate it, adjust its contrast, crop out extraneous detail, remove red-eye and more.

"The amount of computer storage space a file requires

Refers to the specification under which an image has been saved to disk or in which it resides in the computer memory. There are many commonly used digital image formats in use. Some of the most used are TIFF, BMP, GIF,and JPEG. The image format specification dictates what image information is present and how it is organized in memory. Many formats support various sub-formats or flavors.

Is the plane commonly at right angles to the optical axis at which a sharp image of the subject is formed. The nearer the subject is to the camera, the greater the lens image plane distance.

"The general term "image processing" refers to a computer discipline wherein digital images are the main data object. This type of processing can be broken down into several sub-categories, including: compression, image enhancement, image filtering, image distortion, image display and colouring."

The amount of data stored in a image file, measured in pixels per inch (dpi).

The type of device used in digital camera and camcorders to capture an image. The 2 most common types are known as CCD (charge-coupled device) and CMOS (complementary metal oxide semiconductor)

Describes the actual physical dimensions of an image, not the size it appears on a given display device.

"The image stabilization, also called picture stabilization, compensates for image shakiness caused by not holding the camera steady. A few high-end camcorders use the superior optical image stabilization, which employs mirrors or prisms to compensate for detected camera shaking. However, most camcorders use digital image stabilization, which crops the edges off of the image and uses these "spare" pixels to compensate when the camera moves. For even better stabilization, use a tripod wherever possible."

A printer that prints computer files at high resolution on photographic paper or film.

The region of the electromagnetic spectrum adjacent to the visible spectrum, just beyond red with longer wavelengths.

A printer that places ink on the paper by spraying droplets through tiny nozzles.

Any type of information that is fed into a computer. Input can come from digital cameras, scanners, keyboards or a number of other devices.

A phenomenon in a scanner in which two colours that appear the same to an observer are registered as different by the scanner, or two colours that look different to an observer are accepted as identical by the scanner. Instrument metamerism is a non-recoverable error, because the input cannot be determined from the output.

Integration in photographic analysis is defined as the method of averaging all density ( illumination ) values either in R, G, and B, or as neutral density and saving this aggregate value to determine exposure in the camera or the darkroom.

Scanner with additional image processing capabilities, such as OCR, bar code reading, etc.

"Chemical treatment for adding density to an underexposed or underdeveloped negative or print. With prints, it is normally easier to re-make the print

The relative brightness of a portion of the image or illumination source.

A scanning process in which all odd lines then even lines are alternately scanned. Adjacent lines belong to different fields.

Mathematical calculation the scanner performs to increase resolution.

"Although the letters actually stand for International Standards Organization, they also indicate a film's sensitivity to light, or as more commonly referred to, its speed. The term pronounced by the individual letters: I--S--O, not as if it were the word "ayso" The early term was ASA, which stood for American Standards Organization" Slow film have an ISO rating of 100 and less, while fast films are 400 and higher."

"A rating of a film's sensitivity to light. Though digital cameras don't use film, they have adopted the same rating system for describing the sensitivity of the camera's imaging sensor. Digital cameras often include a control for adjusting the ISO speed

A colour calibration chart used in many systems to create profiles. Different IT8 targets are used to characterize different devices such as scanners and printers.
