How it works?

I want to thank the developers for this software!
I want to use it in my research.
Can I get answers to the following questions?

  1. With the help of the orthophoto process is based? On my data sets I didn’t see much difference whether exif data is available or not. I mean, is the track built using gps to make the stitched images go faster ( only close images were compared and stitched, and no time was spent on the distant ones?
  2. what is the problem to add tiff support? Your library of jpeg support?

Now I’m trying to add support for Red Edge to your project, but I have to reformat the resulting images into jpeg.
