If you’ve filmed on a Sony camera and your footage came out flat or grey, you were probably shooting in Sony S-Log 3
That’s not a mistake.
It’s actually one of the most powerful tools Sony gives you for making cinematic, professional-looking video.
If you’ve ever wondered what is Sony S-Log 3 and why it looks so flat, the answer is simple: it works a lot like shooting RAW photos, but for video.
The file doesn’t look great straight out of the camera, but it holds way more information — which means more control when you edit.
Here’s a clear breakdown of what S-Log 3 is, why it matters, and how to use it.
What Exactly Is S-Log3?
S-Log3 is a log colour profile.
Think of it like shooting RAW photos on a camera — the image doesn’t look great straight away, but it gives you way more flexibility when you edit.
Or imagine baking a cake.
S-Log3 is like having all the raw ingredients laid out — flour, sugar, eggs.
It doesn’t look finished yet, but because you’ve got everything there, you can decide exactly how you want the final cake to taste.
It works the same with video.
S-Log3 “flattens” the image: bright areas are pulled down, shadows are lifted, and contrast disappears.
The footage looks dull at first, but all the detail is still in the file.
That’s what makes S-Log3 powerful — it saves highlights and shadows you’d normally lose, giving you way more freedom to shape the look later in editing.
Why S-Log3 Matters
Most video profiles lock you into a certain look.
Once highlights are blown out or shadows are crushed, they’re gone.
S-Log3 gives you:
- More dynamic range — detail in both bright skies and dark shadows.
- Room to grade — you can shape the colour and mood in editing.
- Consistency — easier to match clips shot on different cameras.
That’s why creators and filmmakers rely on it.
It’s like a digital negative you can push in post.
Shooting in S-Log3 - Some Quick Tips
- Turn it on: Go into Picture Profiles on your Sony (usually PP8 or PP9) and select S-Log3.
- Expose a bit brighter: S-Log3 doesn’t like dark shadows. Keep your exposure meter around +1.7 — that usually gives clean, bright footage without losing detail.
- Use your tools: Check your histogram, zebras, or an external monitor. The back screen of the camera will always look flat (unless you have monitoring LUT on), so don’t rely on it.
- Stick to base ISO: Most Sony cameras work best at ISO 800 in S-Log3 (depending on the model). Some even have two base ISOs. Start there if you can.
- Keep skin tones safe: Make sure faces look a touch brighter than the middle of your exposure — this keeps them clean and avoids noise.
- Don’t blow out highlights: Bright skies and lights can lose detail fast. Overexpose slightly, but not so far that whites look pure white with no texture.
- Set white balance yourself: Avoid auto white balance. Pick a specific white balance or setting (5600K, daylight, cloudy, etc.) so your colours stay consistent across clips.
Editing S-Log3 Footage
Drop S-Log3 clips straight into your timeline and they’ll look washed out.
That’s normal.
To fix it, apply a conversion LUT — basically a preset for video.
It adds back contrast, colour, and saturation.
From there, you can fine-tune.
We built Sony S-Log3 Conversion LUTs designed to make this quick and consistent, so you don’t have to start from scratch.

When to Use (and Skip) S-Log3
- Use it for high-contrast scenes, projects where you’ll grade in post, or when you want a cinematic look.
- Skip it for casual shoots, fast turnaround, or when you don’t plan to edit much.
S-Log3 in a Nutshell
S-Log3 can feel intimidating the first time you use it. The footage looks flat on purpose.
That flatness is what preserves the detail.
Expose carefully, apply a LUT, and you’ll unlock clean, cinematic footage with way more flexibility than standard profiles.
