Imaging Science Foundation Calibration
ISF Calibration in United States
The Imaging Science Foundation was established by Joel Kane and Joe Silver in 1994. The goal of these video professionals was to educate both end users and manufacturers in ways to improve video display and source device accuracy. The former with the creation of in-depth training courses to enable a better understanding of all forms of video display devices and how to properly adjust them. From these training courses an examination and consequent certification was devised and the concept of ISF calibration was born. Manufacturers continue to be advised by the Foundation on ways to implement and improve proper calibration controls and picture memories, so that ISF Day and Night presets can be enabled and where possible locked to prevent inadvertent changes.
The ISF calibration process involves a suitably qualified video calibrator coming to your home or place of business with the intention of creating an accurate image on your display. The point of any video calibration is to align the TV, monitor or digital projector against a known reference. This usually takes the form of a test pattern generator. In order to experience watching a television show or movie in the way it was intended to be viewed by the director or director of photography is to do so on a correctly calibrated display. Once the video display has been adjusted to achieve the most accurate image possible given the restrictions of the on-board controls, the sources can be taken into account. This is important as merely measuring the image against a known reference doesn’t take into consideration any differences a source device may introduce into the chain. In instances where the built-in controls are so poor that an accurate image cannot be attained external 3D LUT devices are available which work around the internal controls and yet still achieve the end result.
The Imaging Science Foundation currently runs courses throughout the United States as well as various countries in Europe. The courses cover many topics and areas in a short period of time ranging from the different types of video displays, picture controls and the history of imaging science. In addition to the theoretical knowledge there is also provision for hands on time spent at the end of the course covering the all-important practical aspect of the ISF calibration process.
