Jan 13, 2016 at 22:25 comment added Dave X Since the OP mentions an easy ExifTool script, Exiftool has an example of a couple more user-defined GPSPitch and GPSroll tags in the sno.phy.queensu.ca/~phil/exiftool/config.html page. If you can write an app on a phone to log these while snapping pictures, you'd be done.
Dec 31, 2014 at 1:50 comment added Sherwood Botsford The image quality of a cell phone is problematic, and in general it is too wide angle. It also has a fairly small exposure latitude, and is unable to compensate for back lighting, which will be common in shooting crowns.
Dec 31, 2014 at 1:48 comment added Sherwood Botsford AFAIK the phone does not record axis information with an image. In addition, while 3 axis, I think the third dimension is used only to get a magnetic bearing when the phone is out of level.
