Our eyes perceive brightness differently than an electronic sensor does. Video monitors are locked into a standard for color and contrast, but now Digital Cinema camera systems are being used to capture images that are used and displayed in media that can see well beyond those limitations.

What does this mean, how does one use it, and what capabilities does it represent?

In the first of a series of Technical Resource articles, CineTechnica present an introduction to the concept of LOG, its origins and capabilities. Click here for the article.
