Getting Your Camera Verified
A practical guide to maximizing verification badges on your Mavica uploads — from preserving EXIF to understanding scan results.
Why get verified?
Camera verification badges are trust signals visible on your posts and marketplace listings. A green "Camera Verified" badge tells other community members that your image genuinely came from the camera you claimed.
Step 1: Preserve your EXIF data
The most important step is uploading images with intact EXIF metadata:
- Copy directly from media — Get JPEGs straight from the floppy disk, Memory Stick, or CD
- Avoid social media re-downloads — Instagram, Twitter, and most platforms strip EXIF
- Be careful with editors — Some software removes EXIF on export. Use "Save As" with metadata preservation enabled
- Don't convert formats — Keep images as the original JPEG; converting to PNG strips EXIF
Step 2: Register your camera
Go to the Upload page and select your exact camera model from the Gearbase picker. If the system detects your camera from EXIF data, it will auto-suggest the correct model — just confirm it.
Pro tip: Register your camera in your profile under "My Cameras" for one-click selection on every upload.
Step 3: Upload at native resolution
For the strongest verification:
- Upload the original file without resizing
- The system checks that image dimensions match your camera's known output
- A 640×480 image from an FD88 will verify perfectly; a resized 1920×1080 version won't match
Understanding your scan results
After uploading, expand the "Image Verification Pipeline" on your post to see:
Tier 1: Safety Scan
- Shows content safety score and processing time
- Most Mavica photos pass instantly
Tier 2: Camera Verification
- Shows detected camera model from EXIF
- Shows whether resolution matches expectations
- "Camera Verified" = perfect match
Tier 3: Sensor Fingerprint
- Only available for cameras with reference signatures
- Shows NCC (Normalized Cross-Correlation) confidence score
- "Sensor Verified" = strong match; "Sensor Plausible" = moderate match
Troubleshooting
"Unverified" despite using a real Mavica?
- The image likely lost its EXIF data. Try uploading the original file from the camera's storage media.
"Camera Mismatch" warning?
- You may have selected the wrong model. Check that your camera selection matches the EXIF Model tag (e.g., "MVC-FD88" not "FD87").
No Sensor Fingerprint badge?
- Not all camera models have reference signatures yet. Check the Gearbase page for your camera to see if a signature exists.
- Reference signatures require multiple verified images to build. As the community uploads more verified photos, coverage will expand.
Badge reference
| Badge | Meaning |
|---|---|
| Camera Verified (green) | EXIF metadata confirms your camera |
| Camera Mismatch (amber) | EXIF doesn't match your selection |
| Sensor Verified (cyan) | SPN fingerprint strongly matches |
| Sensor Plausible (blue) | SPN fingerprint moderately matches |
