Linear color space is good for visual effects and very simple color corrections like exposure adjustments. For more creative, telecine-style color correction (such as what you might do with SCRATCH or Color or Colorista), you want log or video images. Most TV shows are corrected in video space without a LUT, and most movies are color corrected in log with a filmout LUT.

Thanks for the link. I must have missed that one.

Funny you should mention SCRATCH. I know when grading R3D's in SCRATCH you are grading in linear color space with a display lut.

OK, one more question. If you are grading Genesis Panalog footage for TV, would you just start grading until it looks good, or would you use some sort of a inverse lut to get closer to a video space before you start grading?

Thanks for the great blog, and discussion.

The vast majority of the time, a Genesis shot television program is handled through a standard television post path - assemble from SR tape originals, color correct on a DaVinci (no LUT, it's handled as standard video), record to another SR tape for titling, formatting, and delivery duplication. The Panalog curve was designed (in part) to allow for this type of approach.

I agree, but when you "use redlog" you could be doing something very different than when I "use redlog." It doesn't mean only one thing, and it does not guarantee that the full dynamic range of the camera is preserved.

I've had the same experiences with cineon log files. Scanning guys deciding where they want to put the exposure without consulting anyone in the chain. It not a big deal but nonetheless happens.

With redlog, my post supe dictates the redlog setting which is set everything to default and exposure to -.2.

Seems something like that is what you want so no one else in the chain can mess with image. Is it more about control then?

It's always more comfortable in the company of your own fanboys.

You are absolutely right. The current argument I am having with myself is "why do I bother posting anything here?"

Bye,

The argument which lacks a thought like:
"because there are Red users who really appreciate and are happy to learn the knowledge I have to share".
Don't give up, Stu. ;-)
