I have photos from an XT2 that I can't get to process. There must be some trick to it that I can't figure out. We flew the site at 90% overlap and it looks like there is plenty of overlap but they will not process. Do I need accurate camera/lens properties…

Is there any benefit to processing one set of pictures then adding more pictures and processing again? does it keep the original main component and add to it or does it start over completely? I am asking because I am trying to get pictures from an XT2…
