Are there any applications (Windows or Linux) that support the .nar format that is used by Windows Phones to store HDR images? In particular I am wondering if there are programs that allow to change the HDR exposure of the image in the same way as can be done on the phone when I download the .nar container (which can be opened as a zip archive) to a computer.
In the .nar container I find the following files:
- EV0.jpg, ArtisticHDR.jpg, NaturalHDR.jpg
content.xml basically contains a listing of the files:
<image properties="Natural">NaturalHDR.jpg</image> <image properties="Artistic">ArtisticHDR.jpg</image> <image properties="Original">EV0.jpg</image>
richsettings.xml contains a "blend value":
and some tags that seem to be references to the images but they are integers and so I am not sure which jpegs they refer to (e.g.
As the archive contains the "original" image but none with higher / lower exposure (only *HDR.jpg that are already processed) I am tempted to assume that the photo app (when you re-adjust the exposure) only interpolates between two of the files in this archive? This would be easy to do in any image editing software.
