(Asked by: username_0 on 2015-09-16)

Most of the controls I at least have a basic understanding of from Photography and other design applications (Affinity Photo / Photoshop / Lightroom etc). But not Pivot.

In the [SpeedGrade Manual](https://helpx.adobe.com/pdf/speedgrade_reference.pdf) the word Pivot doesn't exist at all. Pretty big omission but I'm resourceful and know other applications exist. So even though I don't use it I pulled up [DaVinci Resolve's guide](http://documents.blackmagicdesign.com/DaVinciResolve/DaVinci_Resolve_12_Manual_2015-07-27.pdf) which states

> **Pivot:**

Perfect cause this actually sounds like exactly what I need. Except when I use it there's absolutely no change in my video and I've got no idea why:

Here's the original:

Here's the footage with the pivot greatly pushed up, yet no change:

I don't know if I'm not understanding the Pivot or what. I'm not seeing any difference though.

If you want to lift or lower your midtone details, I would suggest that you use a gamma or midtone control instead.
