Using Readings From Gloss Meters

[Ihno]

It'd be very interesting alright to have something that's taking a small, non tiling patch that can capture quickly as an on set tool. Of course the internal battle rages on about what our renderer is but something like this would be a big plus point, especially if it's fast on set...

Jep 1+

it'll also give you acesCG (aka linear) values.

Um.. does that mean acesCG is actually linear or that you can convert it to linear without the need for fiddling with color checker and all the mistakes one can make doing that?
*searches for cameras that shoot acesCG*
A little off topic (sorry for that)

Yeah aces space is linear and the lovely thing about it is that the organisation has put the burden on the camera makers to provide a transform that turns their particular camera footage into aces or linear. It just means that if you're shooting with multiple cameras and all of them use aces, you can mix and match footage far more easily as once you pop on your camera > aces transform (done in the nuke read node) you're gonna get pretty similar results if you're shooting the same scene. You'll still need your colour checker and grey ball on set as if you're shooting with nothing but purple lights for example, you wouldn't expect your middle grey macbeth swatch to come out neutral purple.

It's not 100% perfect for CG and has a few problems with really bright values (like we make in our renders all the time) but it's made working with footage waaaaaaay simpler than it was before.
