Mystery Log: A Survival Guide Part 2 – Cineon Film Log

Using Cineon as a Predictable Base When Metadata Goes Missing

In this second installment of Mystery LOG, we explore how the Cineon Film Log gamma, designed initially to digitize film negatives, can be a stable fallback when you don’t know your footage’s source settings. In Part 2, we use a Color Space Transform (CST) to create a “soft landing,” giving you a clean, editable image without committing to an inaccurate LUT or metadata guess.

Cineon Log as a neutral tone curve

In Episode 1, we covered the visual survivalist approach: grading blind using scopes, contrast clues, and your instincts. But what if you want more structure—something to anchor your grade without pretending you know what camera this came from?

Our Cineon Film Log Color Space Transform (CST) trick begins here.

I first encountered this technique while working on a series where B-cam footage came from an unknown DSLR with no camera reports. Not a single LUT worked; every alternative CST broke the image weirdly. So, I reached for something old—Cineon Film Log, initially developed by Kodak in the ’90s to scan film negatives.

Cineon Film Log’s smooth and forgiving curve gives you something predictable. It’s not a perfect match for anything, but it’s close enough to almost everything to work as a neutral base.

Most modern log gammas—LogC, V-Log, S-Log, even Canon Log—are mathematically influenced by Cineon, making it a solid fallback when you’re flying blind and don’t want to rely 100% on your eyes (see Part 1) for the initial transform.
