LOG encoded video has its roots in the development of the Cineon System from Kodak. Now, traditionally, the manipulation of film was done with a photo chemical process, but in the 80s and early 90s with so much film being scanned via what's called the telecining process to video tape formats, operators noticed that they were missing sort of the density of the original film negative. - That's sort of the rich color and the blacks. - Yeah, the push and pull, exactly. And some very smart folks from Kodak developed the Cineon System that scanned the film logarithmically, essentially, this lets a tremendous amount of image information be preserved when the film was scanned to what are call .cine files and later, after SMPTE got involved, they called those files DPX image sequences.
