THETA X
The X benefits from better HDR processing as well as higher resolution.
SC2
We can likely take a better shot from the SC2. The lighting was difficult as sun was coming in from the window.
Full size images from car interior (can be downloaded for close inspection)
Main observations
- Changing bitrate makes a significant difference in filesize but not visible quality
- X quality of auto interior shots is noticably better than SC2
