Every camera offers a log profile now. S-Log, C-Log, V-Log. But should you actually use it? Depends on the project.
What Log Actually Is
A flat color profile that preserves more dynamic range. It looks washed out straight out of camera, but it gives you more flexibility in post — especially in highlights and shadows.
When to Shoot Log
Use log when:
- High dynamic range scenes: Bright windows + dark interiors, backlit subjects, harsh sunlight
- Heavy color grading planned: You want a specific look that requires significant correction
- Matching footage across cameras: Log profiles make it easier to match different camera brands in post
- Broadcast or cinema delivery: High-end deliverables justify the extra work
When to Skip Log
Use Rec.709 (standard profile) when:
- Quick turnaround: You don’t have time for a full color grade
- Simple lighting: Controlled environments with low contrast
- Web delivery: YouTube, social media — viewers won’t notice the difference
- Client wants to see it on set: Log looks terrible on a monitor without a LUT applied
The Hidden Costs of Log
Shooting log isn’t free. It requires:
- More post time: Every clip needs color correction, not just grading
- Better monitoring: You need a LUT applied to your monitor to see what you’re actually capturing
- Higher bitrates: Log falls apart with heavy compression. Shoot ProRes or high-bitrate H.265
- Proper exposure: Underexpose log and you get noise. Overexpose and you clip highlights. The margin for error is smaller.
The Exposure Myth
People say “expose to the right” with log (push exposure as bright as possible without clipping). That’s true for some profiles (Sony S-Log3), but not all. Check your camera’s documentation. Some log profiles want middle-gray at 40-50 IRE, some want it lower.
Log Without a Colorist
If you’re grading it yourself and you’re not experienced, log can look worse than Rec.709. A bad log grade is flat, muddy, and lifeless. A well-shot Rec.709 image looks good straight out of camera.
Don’t shoot log just because you can. Shoot it when you need the extra latitude.
LUTs: The Shortcut
Most cameras ship with LUTs (Look-Up Tables) that convert log back to Rec.709. Apply the LUT in post, then tweak from there. It’s faster than building a grade from scratch.
What We Actually Do
Commercial work with controlled lighting? Rec.709. High-contrast outdoor work or mixed lighting? Log. We pick based on the scene, not the camera’s capabilities.
