  Here's an example of 45 20megapixel photos stitched together. ca: 88x40in @ 300ppi ca: 132x60 @ 200ppi ca: 260x120 @ 100ppi (~21x10 feet!) It's possible to stitch without distortion like that shown in my example. Also, FYI the camera is a tiny mirrorless camera (sony a5100) that was modified by removing the infra-red filter that covers the sensor.  It's hard to wrap your head around the process. Typically, you will be using a moderate telephoto lens for the process and can make a super-wide angle final pano. In this case, the lens was a 50mm on APS-c (75mm equivalent).

Recently I acquired an infrared converted camera. Somebody on Ebay converted a conventional Sony A5000 by simply removing the IR filter over the sensor. Unlike many professionally converted cameras, my IR camera does not have any IR filter over the sensor. So without a filter over the lens images don't look that different from a conventional camera. But I've been using a 720nm IR filter. To the eye the filter looks black. But through the camera you can see an image. And surprisingly the daylight exposures are very similar to conventional photography. One issue that is very much subjective about the use of digital infrared is how to process images. There's no way to be true to what you see, the IR world is magically different! For most of the IR work I've done so far, I've converted to grayscale. And unlike conventional photography, I'm ok with seriously moving those sliders around. Opening the shadows and pulling in the highlights to the extreme doesn't
