How DaVinci Resolve 12 changes the way we write contrast curves in the LAB Colorspace. See the difference between Resolve 11 & 12 curves.

Before & After: Building Contrast Curves with Resolve 12

If you missed it, Dan and I have previously done a 5-Part series on color correcting in DaVinci Resolve using the LAB colorspace. Working in LAB has been possible in Photoshop for many years. And in Resolve 11, Blackmagic gave us the ability to grade in LAB with moving images. In my follow-on series to Dan’s original LAB Insight, you join me on my journey learning to work in this Colorspace. And that journey wasn’t all unicorns and rainbows, it was often frustrating.

There was a HUGE annoyance working in LAB in Resolve 11

For many years, Resolve limited the types of curves we could draw—making working in LAB rather tedious and somewhat annoying. Curves that could be drawn in Photoshop with two quick moves, required us to place up to 5 points in Resolve. And there’s always the chance our curves would introduce color balance problems in the highlights or the shadows.

Davinci Resolve 12 has solved this annoyance

We can now precisely replicate the curves-writing done by Photoshop artists, with the new Curves interface in DaVinci Resolve 12. In this Insight, I’ll use the Outer Darkness project, which I did the contrast expansions using LAB, showing the difference between the curves I had to write in Resolve 11 and what they’d look like if I were starting the job in Resolve 12.

Visually, the difference between the two approaches is minor. But in terms of speed, workflow, and precision? Resolve 12 is the hands-down winner. Watch the video for the full demo.

  • Great follow up! DO you still use power grades or has it gotten clean enough that you just do it manually w curves when needed. Also, do you ever use the Y only curve in the L node to expand contrast or simply LGG. Simply personal preference?

  • Love the LAB stuff, was looking forward to this topic again with R12, Thanks Pat! Curious about same things as Jason, any chance you will do drx files like previous round of insights on this topic?

  • Hey Colin, glad to hear LAB is a common interest. My question was more along the lines of has it gotten easy enough to use that we no longer need those power grades? I believe they were mainly to ensure the point was perfectly centered but its super easy to do that now in R12.

  • is the LAB node support totally broke in resolve 12.5.3? it gives me a black screen.

  • Patrick Inhofer

    I’ll take a look this afternoon and get back to you.

  • it tripped out in this one project until I restarted weird.
