    Alister Chapman series of posts explaining how they work and when you should use them. Very clear as all the stuff that he writes.

    Understanding Gamma, Cinegamma, Hypergamma and S-Log:

    Also:

    Jesse Rosen (AbelCine) wrote an article explaining the technical definition of LOG-encoded video and how it differs from a viewing gamma such as REC709:

    Mitch Gross (AbelCine) shot this video illustrating the differences between recording in standard gamma (such as REC709) versus LOG recording:

    Has it been stated if Hypergamma and S-Log will be available out the standard HD-SDI or are those curves only relegated to the dual link HD-SDI?

    Joe you should ask your question in the "Painter - F3 short" thread. Nigel would be able to answer that as he used the camera to a degree that no one else has in the public to date.

    Something is up with Alister's site. Most of the posts for this year have disappeared, including the ones listed above.

    Thanks Fohdeesha for pointing it out. Alister's server was down for a couple of weeks. I edited the post with the new links that are working ok now (and I added a couple more from abelcine).
