GyroScan is a little intimidating.
It works a lot like the panorama function on your iPhone’s camera, but you can capture a complete 360-degree image either horizontally or vertically by spinning in a circle or rotating your phone up or down. When you look at the instructions, it all gets very technical, but once you work with it for a little while — and maybe rig something up to keep your phone still — you can get some really good results.
You can also scan in “stereo mode” and make 3D pictures, but that’s just showing off, GyroScan.
