Why I Spent Over a Year Building an Exposure Workflow for the S5IIX
What if you never had to guess your exposure again?
That question kept me at my desk for over a year. Testing, calibrating, throwing out versions that didn't hold up. All of it on the S5IIX.
Today I can finally show you the answer.
What I built
The CWM Exposure Toolkit · S5II / S5IIX Edition is a complete on-set-to-grade workflow, calibrated specifically for the LUMIX S5II and S5IIX sensors.
It's built on one idea: ETTR 1, an exposure method that gives you a mathematically repeatable reference from the moment you expose to the moment you grade.
No guesswork. No generic presets. Just the freedom to focus on your story.
Why exposure is the hard part
V-Log is incredible. The dynamic range is the reason I keep coming back to this sensor.
But nailing exposure in V-Log has always been the weak link. You're looking at a flat, desaturated image and trying to judge whether your skin tones are sitting where they should be. Get it wrong, and you either crush the shadows into noise or clip the highlights beyond recovery.
Generic LUTs don't solve this. False color maps that ship with monitors are calibrated for broadcast standards, not for V-Log's specific response curve.
So I built my own.
What it actually took
I've been testing this thing in every environment I could find — all of it on the S5IIX, because that's the camera I shoot. Different locations, different lighting, different skin tones. A lot of beta testing before it even got close to where it is now.
The goal was clear from day one. What I didn't expect was how long it would take to get there.
Because here's the thing — when you first look at it, it seems simple. A false color LUT and a PowerGrade. That's it. Two files.
But the calibration? Finding the right zones, testing them against real footage, adjusting, testing again? That took far longer than I ever planned for.
Several weeks on a single color zone. Exporting, importing back into the S5IIX, shooting, checking. Then doing it all over again. And again.
I lost count of how many rounds of testing it took. More than I'd like to admit.
That's the part nobody sees. And honestly, that's the part that makes it work.
I'm happy to finally give you a preview. And soon, I'll be able to put this Exposure Toolkit into your hands.
What's in the toolkit
ETTR 1 False Color Monitoring LUT — loads into V-Log View Assist for in-camera exposure verification
11-Node CST PowerGrade — a complete DaVinci Resolve grading pipeline

What it changed for me
It completely changed how I expose in camera and fine-tune in post.
One pipeline. From the sensor to the grade. And underexposure becomes a thing of the past.
That's the part I'm most excited to show you properly. This video is a preview — the full walkthrough comes at launch.
