Having just completed my first photo field, I would like to put in my two cents for this forum. The key problem I had was stitching the photos to create the panograph image. I used professional gear and an expert photographer to take the photos. One of the things I would do differently is make sure that the pictures of the sky include the horizon (we just arbitrarily used 30 degrees) The stitching software had trouble stitching the clear blue sky. I tried two free on-line programs to stitch the pano, Hugin, and PTGUI. PTGUI did a great job of creating the pano, sky and all, however, the free version of PTGUI leaves thousands of watermarks on the finished product. Hugin had a problem stitching the sky and leveling the horizon. In the end, I used a program, AUTOSTITCH 64. Although it had problems stitching the clear blue sky, it did a great job stitching the ground and horizon. I used Photoshop to create a sky. My finished pano was 21,000x10,500.
Problems encountered were:
The pano horizon has to be level and in the middle (vertical) of the pano. If you see that the aircraft in Real Flight does not get smaller, or gets too small, as it heads away from center, then you need to change where the horizon is on the pano and re-import it into Real Flight.
The forum here was very helpful, but there is a lot of research needed to do a Photofield properly.
