Theta Stitcher + No Compatible DNG Files

There’s some sample DNG images here:

The DNG file is about 50MB.

The file you sent is about 6MB.

In addition, despite the file name being DNG, the metadata indicates that the file is JPEG.

If I change the file extension to JPG, I can open the file in Preview, which can’t open dng.

If you’re using a Mac, there may be problems with transferring large files from the Z1 to the Mac.

There’s a utility called image capture that comes with the mac that can transfer the files over.

Is the DNG image you posted directly from the Z1? Or, did you process it?
