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:
