At CES 2017, Insta360 announced the Insta360 Pro, a professional 3D 360 camera. Insta360 has now provided samples from the Insta360 Pro.
Here is a 3D 360 sample photo. This is only a compressed version on Google Photos and is not the original quality.
Here is a 100% crop. At this close up view, we can see the image looks very clean and detailed, but perhaps a little too smooth. I will find out from Insta360 whether it is possible to get unprocessed raw photos.
Stitching was generally excellent but there was a part with a clear stitching error.
Here is the same scene but without a stitching error.
Here is a link to full-resolution samples, including video. Thank you very much to Steve Swayne for bringing this to my attention!
