If you're a Windows Insider on the Fast Ring of Windows 10 Mobile, then the Camera app should be updated for you. A new version of the app is out for Fast Ring Insiders with HDR improvements.
- Now you can take 3 HDR photos consecutively before saving shots.
- Bug fixes for reliability and performance
- User experience improvements

Use the Windows Store to update the Camera app. Alternatively, you can use the following link to grab the updated Camera app:
