Maximizing Contrast Ratio: The difference

between the darkest and lightest image details and

display can reproduce.

Optimizing Gray Scale: Adjusting gray scale

means the display properly reproduces the color of

white at D6500 degrees Kelvin. This is done by

adjusting the ratio between the Red, Green, and

Blue (RGB) pixel levels. All colors reference this

"white point" so it is critical it be set accurately.

Optimizing the Gamma Curves: This defines how

much light the RGB pixels emit for any given

brightness level. This setting is important to get the

detail in the shadows.

Optimizing Color-Space and Reproduction:

This is directly linked to the gray scale optimizing.

Flat Field Uniformity: The projector displays a

pure white image from a white test pattern, free of

any blotches or colors that alter the image.

Fundamentally, ISF calibration is the process of optimizing the projector or the flat panel display to reproduce the information from video and data sources (DVD, HD, Satellite, PC, etc) in a manner that closely approximates the quality and dynamic range experienced in a 35MM film theater. Seeking the "holy grail" of film performance and dynamic range, calibration involves color, contrast, and detail along with the environment but avoiding the image jitter ans "artifacting" of the film experience. The main element of calibration are:
