A computer program used to edit, manipulate and modify digital images. Such programs can be used as digital darkrooms to correct colours and exposure, remove flaws, crop images and enlarge elements. They can also be used to add text to images and to achieve other artistic effects. Adobe Photoshop CS and Photoshop Elements are examples of such applications. Many digital camera manufacturers bundle custom image editing software or Adobe Photoshop Elements with their products.

INKJET PRINTER
-
A printer that sprays tiny droplets of ink through nozzles to produce an image on paper. Today’s inkjet printers can produce high quality colour prints that are virtually indistinguishable from traditional photographs. (However, Inkjet prints are more likely to fade over time and also may smudge if handled improperly and are fairly expensive per print.) The size of ink droplets is expressed in picolitres and, the smaller the droplet, the finer the image. SEE ALSO PHOTO PRINTER.

INFINITY
-
The farthest point upon which a camera can focus, which is roughly 50 feet. When a camera’s focus is set to infinity, everything that is fifty feet or more from the camera will be sharply in focus.

INTERPOLATION
-
A technique used by digital cameras, scanners and printers to increase the size of an image in pixels by averaging the colour and brightness values of surrounding pixels.
-
ISO SPEED
-
A camera’s sensitivity to light. The higher the ISO speed, the greater sensitivity to light. However, high ISO speeds often result in images that are grainy or have artifacts. ISO stands for International Standards Organization, a non-government body that oversees the creation and application of uniform standards See also ARTIFACT.
