The most time consuming part I found doing a photofield of our airfield was getting the center of the pano image (horizon line) correct. I did this by adjusting the image's angles in the editor and in Photoshop and testing. And testing, and testing. I'm just about done with it and I know I have well over 30 hours of time invested. Take your time, and be patient.I want to create with the photos taken of the field I fly.
