Digital Photography Glossary

Photography Glossary - I

Understand the terminology of digital photography, digital printing and digital imaging so that you will become a better photographer. Photographic terms such as ICC, ICC Profile, Incident Light Meter, ISO, ISO Speed, and more.



ICC stands for International Color Consortium, a group of practitioners, scientists and technicians who’s purpose is to advocate an open, cross-platform, cross-medium color management system.


ICC Profile

ICC stands for International Color Consortium, and this organization has developed a vast series of databases for specific color space profiles. A color profile is a dataset that describes all the specific color attributes for an input (camera, scanner) or output (monitor or printer or paper) device in the digital photography workflow. The color profile enables you to match the calibration on all the devices in the chain, so they can interpret or read color the exact same way. For example, this guarantees that the crystal clear blue waters of the Caribbean off Bermuda look the same on the camera’s LCD display, your MacBook Pro’s LCD screen and on the Kodak Super Glossy paper printed from your Epson inkjet printer.


Image Stabilization

IS (Image Stabilization) is a gyroscopic technology that has been incorporated into many high-end SLR lenses to reduce camera shake on longer focal length lenses, or when the camera isn't stable enough for crisp, sharp photos.


Incident Light

Incident Light is light coming from a light source that falls directly on a subject and provides sufficient illumination to view it.


Incident Light Meter

Hand Held Light Meters

Incident Light Meter is a specific type of light meter (or light meter configuration) that measures the light directly falling on to a subject; as opposed to being reflected off of a subject.


Inkjet Printer

Inkjet Printer is a printer that uses liquid or semi-solid ink as its base pigment to print photos, or regular text, on paper and other printing materials.


Interpolated Resolution

A photographic image resolution that is measured in DPI (dots per inch). Computer software has the ability to enhance or increase an image's resolution by guessing at the color of the dot in between dots of a known color. This guess is the interpolation, and the final result is interpolated resolution.



Infra-Red (IR Light) is at the end of the electromagnetic spectrum beyond the reds (long wavelengths). IR light is not visible to the human eye. Cameras and optical equipment designed for IR are able to detect heat signatures which are invisible to us.


ISO Speed

ISO Sensitivity and Image Quality

ISO Speed is an international standard value that indicates an image-sensor's, or film's relative sensitivity to light. The lower the number, the less sensitive to light it is; and the converse is true, where a high number corresponds to greater sensitivity to light.
