Editing Log footage is often misunderstood—especially with newer color science like Log3G10 on the Nikon ZR. While many tutorials simply show how to apply a LUT, real-world grading requires a deeper understanding of exposure, color space, and workflow decisions.
This guide is based on practical grading experience, not just technical setup. It will help you:
- Avoid common Log3G10 mistakes
- Build a clean, flexible node structure
- Achieve cinematic results consistently in DaVinci Resolve
What Makes Log3G10 Different?
Log3G10 is not just another log profile.
It originates from RED’s color science and is designed to:
- Preserve highlight detail
- Maintain smooth tonal transitions
- Provide consistent grading across cinema workflows
Unlike standard log formats, Log3G10 is built around wide gamut + log gamma, which means:
So, you must manage color space correctly, or the image will look flat, noisy, or inaccurate.
According to Nikon’s official workflow, Log3G10 is intended to be transformed via LUT or CST before final output .
Recommended Editing Setup
Before you begin color work, ensure DaVinci Resolve is properly configured for Log3G10:
Basic Project Settings
- Timeline color space: DaVinci Wide Gamut Intermediate
- Input color space: REDWideGamutRGB / Log3G10 (for R3D files)
- Output color space: Rec.709 (or DCI-P3 for cinema delivery)
- Bit depth: 10-bit or higher
Hardware
- GPU with at least 8GB VRAM (Resolve loves GPU power).
- Fast SSD or NVMe drives for 6K RAW footage.
- Use proxies or optimized media if playback is choppy.

4. Importing Nikon ZR Footage
Depending on your recording format:
🎞 R3D RAW or N-RAW (.NEV)
- Import directly into Resolve.
- Resolve recognizes RED metadata automatically for R3D.
- For N-RAW, install Nikon’s N-RAW plugin (if required).
🎬 ProRes or H.265 Files
- Use “Color Space Transform (CST)” node to manually convert from Log3G10 → Rec.709.
- Alternatively, apply an official Nikon ZR LUT.
Real-World Workflow: What Actually Works
After testing multiple grading approaches (LUT, CST, Color Managed), here’s the workflow that consistently delivers the best results:
Method 1: Color Space Transform (Recommended)
Why this method works better
- Non-destructive
- More flexible than LUTs
- Cleaner highlight roll-off
Node Structure (Pro Workflow)
Node 1 – Exposure & White Balance
Node 2 – Contrast & Primary Correction
Node 3 – Secondary Adjustments (skin, hue)
Node 4 – Color Space Transform (Log3G10 → Rec709)
Node 5 – Look / Creative Grade
CST Settings
- Input Color Space: REDWideGamutRGB
- Input Gamma: Log3G10
- Output Color Space: Rec.709
- Output Gamma: Rec.709
So, this matches official recommendations from Nikon’s technical guide
Real Insight (Important)
If you apply CST too early: You lose highlight flexibilit, skin tones become harder to control. Always grade before CST
Step 1:
Step 2: Load the LUT: Open Project Settings (gear icon at the bottom right).
Step 3: Go to ColorManagement.
Step 4: Click Open LUT Folder — this opens your LUT directory:
- Windows:
C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\LUT - macOS:
/Library/Application Support/Blackmagic Design/DaVinci Resolve/LUT/
Step 5: Create a new sub-folder (e.g., RED) and copy the Log3G10 LUT file into it.
Step 6: Back in Resolve, click Update Lists to refresh LUTs.
Method 2: Using LUT (Faster but Less Flexible)
You can use RED IPP2 LUTs for quick conversion.
When LUT works well:
- Fast turnaround projects
- Social media content
- Consistent lighting
When LUT fails:
- Mixed lighting
- Underexposed footage
- Complex skin tones
LUT is a shortcut, not a solution
This ensures your adjustments are made in the Log space for maximum tonal flexibility.

6. Tips for Working With ZR Log3G10
- Always shoot slightly overexposed (+0.3 to +0.7 EV) to preserve detail in shadows.
- Use false color or waveform on set to monitor skin tones (~55–65 IRE).
- Avoid adding LUTs too early—grade exposure first, then stylize.
- Export in 10-bit ProRes 422 HQ or 12-bit DNxHR HQX for final masters.
- Keep ISO consistent across clips to simplify grading.
- Use Scopes (Waveform, Parade, Vectorscope) in Resolve to maintain color accuracy.
- For delivery:
- Export to ProRes 422 HQ or DNxHR HQX for professional projects.
- Use H.265 10-bit 4:2:0 for YouTube or online content.
- Save a custom preset in Resolve for future ZR Log3G10 projects
7. Common Issues & Fixes
| Problem | Likely Cause | Fix |
|---|---|---|
| Flat or gray footage | Wrong gamma/gamut | Apply CST or correct LUT |
| Highlight clipping | Incorrect exposure on import | Adjust RAW exposure metadata |
| Skin tones too red/orange | Saturation too high | Lower chroma in midtone range |
| Banding | Exported at 8-bit | Always deliver 10-bit or higher |
Real Production Example
Real-World Grading Test: Log3G10 vs LUT Workflow
In a real production scenario, I tested two workflows using Nikon ZR Log3G10 footage:
Scenario: Indoor interview setup; Mixed lighting (window light + LED panel); ISO 3200; Slight overexposure (+0.5 EV).
Test 1: LUT-First Workflow
- Applied LUT immediately
- Adjusted exposure after
Result: Skin highlights clipped quickly; Contrast became too aggressive; Less flexibility in post
Test 2: CST Workflow (Recommended)
- Adjusted exposure first
- Applied Color Space Transform at the end
Result: Smooth highlight roll-off; Better skin tone preservation; More control over shadows.
Final Conclusion: In real-world grading, CST consistently outperforms LUT-first workflows, especially in mixed lighting conditions. This is where Log3G10 shows its strength—but only when used correctly.
Before vs After: What Proper Log3G10 Grading Looks Like
Before (Uncorrected Log3G10): Flat contrast; Desaturated colors; Skin tones appear dull
After (CST + Proper Exposure): Balanced contrast; Natural skin tones; Preserved highlights
Key Insight: The difference is not just LUT vs no LUT—it’s about workflow order and exposure accuracy.
Scenario:
- Indoor interview
- Mixed LED + window light
- ISO 3200
Results:
- CST workflow preserved highlights better
- LUT workflow clipped skin highlights
- Color-managed workflow required more setup time
Conclusion: CST gave the best balance of: speed; control; consistency
Log3G10 vs S-Log3: Real Differences in Grading
From practical grading experience, Log3G10 behaves differently from Sony’s S-Log3.
Log3G10: Smoother highlight roll-off, requires strict color management and more flexible in high-end workflows
S-Log3: Easier to expose, faster workflow, more forgiving for beginners
Real Insight: If you are used to S-Log3 is Log3G10 may feel harder at first. But it provides more cinematic results when graded properly.
Mistakes I Made When First Using Log3G10
When I first worked with Log3G10, I made a few critical mistakes:
Applying LUT Too Early
Result: Harsh contrast, difficult skin tone correction
Underexposing Footage
Result is noisy shadows; color artifacts.
Ignoring Color Space
Result: washed-out image, inconsistent colors
What I Learned: Log3G10 is not forgiving.
But once you understand: exposure; color space; workflow order. So, it becomes one of the most powerful formats for grading.
Why Log3G10 Requires a Different Mindset
Unlike traditional log formats, Log3G10 is designed for cinema-grade pipelines.
That means:
- It expects proper color management
- It assumes controlled exposure
- It is built for post-production flexibility
This is why beginners often struggle with it and why professionals prefer it.
Export Settings That Actually Work
For YouTube / Social Media
- Format: H.265
- Bit depth: 10-bit
- Color space: Rec.709
For Professional Delivery
- ProRes 422 HQ
- DNxHR HQX
- 10-bit or higher
Final Thoughts
Editing ZR Log3G10 footage in DaVinci Resolve combines the best of Nikon’s new cinema system with RED’s color science.
Once you establish a proper Log workflow, the ZR delivers creamy highlights, natural color roll-off, and skin tones that rival high-end RED Komodo and ARRI Alexa cameras.
If you’re serious about cinematic color, Log3G10 on the Nikon ZR is a creative playground—and Resolve is the perfect companion to unlock its potential.
