Can be characterized in terms of absolute film sensitivity or in terms of reproduced image blacks. Absolute sensitivity is simply a measure of what level of light (exposure) begins to produce the first density signal in the film - this is known as toe speed. The toe speed of a film can also be interpreted by a cinematographer as underexposure latitude or shadow detail. The blackness of a positive image D-max can also be used to define speed. Most cinematographers would describe a film with smokier blacks as slower than a film with blacker blacks given both were exposed similarly. Black level also relates to a cinematographer s perception of shadow detail.
