When saving both the JPG and DNG (RAW) photos, the Google Camera application on Pixel smartphones generates DNG
files with missing or invalid metadata (see thereafter for an example).
Multiple bug reports have been reported to Google ([1](https://support.google.com/pixelphone/thread/112616241),
[2](https://support.google.com/pixelphone/thread/43493374), [3](https://support.google.com/pixelphone/thread/156039163),
[4](https://support.google.com/pixelphone/thread/1314238)) but no fix has been provided yet.
This application uses the JPG files and copy their metadata to fix the DNG files.
Simply copy the JPG (`sdcard/DCIM/Camera`) and DNG (`sdcard/Pictures/Raw`) files to a single folder.
Choose that directory in the application and hit the big button!
That's it.
## How To Run
Make sure [ExifTool](https://exiftool.org) is installed and on the path (`exiftool -ver` to test).
You'll also need the JRE (or JDK) 17 to run the application from the JAR or sources.
Run the fat JAR:
```bash
java -jar pixel-dng-fixer-1.0.3.jar
```
Or run the application from sources:
```bash
mvn compile exec:java
```
## Metadata
The following metadata are currently supported:
- ISO
- ApertureValue
- ShutterSpeedValue
- MeteringMode
- FNumber
- ExposureTime
- ExposureProgram
- GPSLatitude
- GPSLatitudeRef
- GPSLongitude
- GPSLongitudeRef
- GPSAltitude
- GPSAltitudeRef
- GPSTimeStamp
- SubSecTimeOriginal
- GPSImgDirection
- GPSImgDirectionRef
- OffsetTime
> **Warning**
> The depth map metadata are missing from DNG files but not copied yet.
This is an example of photo metadata, as created by the Google Camera app with a Pixel 4a 5G and reported by
[ExifTool](https://exiftool.org).
