ISO film speedThe method of film speed (sensitivity) classification developed for the American Standards Association (ASA) and finally adopted by the International Standards Organization (ISO).

Iris OverrideAn override control that allows the iris opening, selected by the automatic exposure control, to be increased or decreased
IrisSynonymous with 'aperture', but now somewhat old fashioned; the variable diameter hole used to control the amount of light passing through a lens.
IRInfrared. That part of the electromagnetic spectrum (light) which lies just below red in frequency (i.e. of longer wavelength than red
IPTCIPTC is the International Press Telecommunications Council standard mark-up for including text (metadata) with images. It is a very useful way to identify, keyword, and copyright your images. Because it is with the image, it never gets lost.
Investment CastCasting where the mold has wax inside, which melts as the aluminum is poured in. This method precludes bubbles and it has less inherent weaknesses than sand casting."
Inverse Square LawThe quantity of light falling on a subject is inversely proportional to the square of the distance from the source
InterpolationInterpolation is a process employed by digital cameras and photo editing software to make an image larger. The algorithms sample pixels and 'guesstimates' what the extra pixels required should look like.
Interlaced Term used to describe an image sensor that gathers its data by first processing the odd lines and then the even lines. See also "Progressive Scan" for the other (preferred) method.
Insert EditingTo add a new shot that goes over an existing shot on a videotape
insert edit allows you to record over the video only (not sound) in camera.
Inner ShadowAdds a shadow that falls just inside the edges of the layer's content, giving the layer a recessed appearance.
Injection MoldingMethod of forming plastic into complex items used extensively to produce underwater housings
InfraredIEEE 1394 is a standard for high speed connection of serial devices. An infrared port on a computer can communicate with other devices without cables.
Indexed Color ModeAn indexed color image is based on a palette of, at most, 256 colors. When you convert an image to indexed color, you create a color lookup table, which stores and indexes the colors in the image.
indexed colorConverting to indexed color reduces the number of colors in the image to at most 256--the standard number of colors supported by the GIF and PNG-8 formats and many multimedia applications. This conversion reduces file size by deleting color information from the image.
In-Camera EditingShooting the shots in the exact sequence that they will be played back
ImpressionistAdds an impressionist effect (like Monet’s art) when the box is checked while using the Pattern Stamp tool.
ImageReadyan Adobe application similar to Photoshop, part of the CS suite, specifically for web design
Image StabilizationImage stabilization is a feature designed to stop blur when at a long focal length. Get a tripod instead!
Image SizeThe dimensions of an image. This is logarithmically proportional to file size i.e. double the image size quadruple the file size
Image ResolutionThe number of dots per inch. For (a given image size) you need four times the number of dots (pixels) when you double the resolution.
ILinkDigital video interface (connection between camera and editing equipment, monitor, computer, etc.) specified in document IEEE 1394. Data transfer speed up to 400Mbit/s.
ICS5A 5 pin O-ring sealed connector used mainly with Ikelite TTL flash units and video lights.
ICS4An obsolete 4 pin O-ring sealed connector used with early Ikelite automatic flash units.
ICS2A 2 pin wet connector used with early Ikelite manual flash units.
ICS10A 10 pin Oring sealed connector used with scientific and technical instrumentation.
ICSIkelite connector system.
ICMImage Color Management. Windows-based software designed to work together with hardware devices to facilitate predictable color
ICC profileThe transforms from device into a standard color space are embedded in a file with the extension ‘.icc’ - this is the ICC profile
ICCA standard for defining device independant color spaces.
