LuttieHow to Edit DJI DNG RAW Files Online (Drone Footage Color Grading)
Grade DJI drone RAW files in your browser. Works with DNG files from Mavic, Air, Mini, and Inspire series. No Lightroom or DJI software needed.
DJI's RAW output is one of the most underused tools in drone photography. Most people shoot JPEG because it's faster to preview, but the DNG files from Mavic, Air, and Inspire series cameras carry dramatically more dynamic range — which matters enormously for aerial shots where sky, highlights, and dark ground are all in the same frame.
Luttie opens DJI DNG files directly in the browser and gives you a full grading environment. No Lightroom, no DJI Master Wheels app, no desktop software.
Supported DJI Drones
Luttie supports DNG RAW files from:
- Mavic series — Mavic 3 Pro, Mavic 3 Classic, Mavic 3, Mavic 2 Pro (Hasselblad)
- Air series — Air 3S, Air 3, Air 2S, Air 2
- Mini series — Mini 4 Pro, Mini 3 Pro (RAW-capable models)
- Inspire series — Inspire 3, Inspire 2 with Zenmuse X7
- Phantom 4 Pro series
Any DJI drone that outputs .dng files is supported.
Why DNG Instead of JPEG for Drone Shots?
Aerial photography creates extreme dynamic range challenges: bright sky, deep shadows on the ground, specular reflections off water, strong sunlight on architecture. JPEG bakes in a tone curve that crushes shadows and clips highlights before you can do anything about it.
DNG files preserve 12–14 bits of sensor data. That means:
- Sky recovery — pull back blown-out highlights to reveal cloud detail
- Ground shadow lift — raise dark foreground areas without color noise
- True white balance control — fix blue-sky color casts or golden-hour drift in post
- Real grading headroom — push contrast and color without banding
For anyone doing aerial photography professionally, shooting JPEG is leaving most of the sensor's capability on the table.
Step 1 — Upload Your DNG File
Go to luttie.app/editor with a Pro account. Drop your DJI .dng file onto the canvas. Decoding takes a few seconds for full-resolution files.
Once loaded, the metadata strip below the canvas shows camera model, ISO, aperture, shutter speed, focal length, and image resolution. For Mavic Pro and Hasselblad-sensor drones, you'll see the Hasselblad designation in the model field.
Step 2 — Set White Balance
DJI's auto white balance performs well in many conditions but struggles with:
- Early morning golden hour (tends to underestimate warmth)
- Blue-sky aerial shots (can introduce slight blue cast)
- Mixed coastal light (water reflections shift WB unpredictably)
Use the Cam WB / Auto WB toggle in the metadata strip to compare the camera-recorded WB against an algorithm-derived neutral WB. For most outdoor aerial shots, Camera WB is a good starting point; Auto WB often helps for overcast or hazy conditions.
You can also fine-tune white balance manually after decoding using the Temperature and Tint sliders in Basic Correction.
Step 3 — Tame the Sky
The most common challenge in aerial DNG grading is the sky-to-ground exposure ratio. Work this way:
- Set Exposure for the midtones (ground, buildings, vegetation)
- Pull Whites until the sky histogram edge sits comfortably inside range
- Lift Blacks slightly if foreground shadows are crushed
For shots with extreme range — bright sun, deep shadow — use the Curves editor. Draw a highlight roll-off by easing the top-right anchor down, and lift shadows by raising the bottom-left. This preserves detail across both ends without global exposure compromise.
Step 4 — Color Grade for Aerial Photography
DJI sensor color science varies by drone:
Hasselblad-sensored Mavic 3 / Mavic 2 Pro — exceptionally accurate, wide color gamut. These files benefit most from careful grading since the sensor captures colors a simple filter can't capture.
Air series — slightly warmer by default. Temperature correction toward neutral is often the first step.
Mini series — smaller sensor, less dynamic range, but still significantly better than JPEG. Keep grades simpler.
A Practical Aerial Grade
- Cool the shadows slightly — push shadow color wheel toward blue/teal. Aerial shadows in daylight lean blue naturally; this enhances rather than fights that
- Warm the midtones — pull midtone wheel toward amber/warm. Balances the shadow cool and gives warmth to land and architecture
- Desaturate sky blues — use HSL Secondary to target blue-cyan range and reduce saturation 15–20%. Prevents oversaturated skies in strong sun
- Add contrast via curves — mild S-curve in the master channel
Step 5 — Color Match from Reference
For aerial landscape work, color matching is particularly powerful. Find a shot of a similar landscape from a photographer or filmmaker whose work you admire, and use Luttie's Color Match feature to transfer their palette to your DNG.
The color match samples color statistics from both images and builds a LUT. Adjust with the Strength slider to blend naturally — for aerial landscape work, 60–75% strength usually looks more convincing than 100%.
Step 6 — Export
Export as PNG or JPEG. With Pro, export your grade as a .cube LUT file to apply across an entire aerial shoot in Resolve or Premiere. A single well-made LUT from a representative DNG frame is more consistent than regrading each clip individually.
D-Log and D-Log M Footage
If you shot video with D-Log or D-Log M enabled and extracted frames, note that Luttie currently operates in display-referred (sRGB) space. For still DNG files this is fine. For log video frames, you'll want to apply a LUT-based log-to-rec709 transform as your first step using the custom LUT drop zone, then grade on top.
