Gallery
Oculus Gallery doesn't allow for accurate viewing of 3d photographs less than 180 degrees field of view. The closet thing we can do is use the 3d180 option which stretches the stereo image across a half sphere, distorting it.
This suggestion is to add an additional image view more that allowed you to look at a 3d image in parallel or straight on, such as into a presinium box. The effect would allow someone to vote a traditional rectangular photograph in stereo 3d without distorting to a sphere.
