Thanks for this masterclass!!

My question is... lift,  gamma,  gain wheels work in rec 709 color space, that being said, if you want to grade for cinema that is dci p3, would you still use lift gamma gain or use other tools like curves and hdr wheels...?

 

Hi Vicent, glad to hear you liked the masterclass.

You can still use LGG for cinema grading, even though they are primarily designed for REC709 / G2.4.
Many Colourists do, however I would always recommend using the offset or HDR grade tool Global first for exposure / wb.
Then use Lift to tweak your black level / Gain for your white level. I seldom use gamma, since the math behind it "bends" the image
in an non-linear fashion. These days I find myself using HDR grade tool Global / Temp / Tint for a lot of the heavy "lifting" (not lift as in black level).
When set up correctly the HDR grade tool is colour space aware, meaning that it manipulates the image with the source colour space / gamma in mind. Which again yields cleaner grades. Custom Curves are also color space aware when set up correctly in a Color Managed project.
However a never use Custom Curves for shot by shot balancing, but I do use them during more scene based look-design such as split-toning and contrast curve adjustments that span an entire scene or movie. Hope this helps.

Cheers 

Dylan
