This is a very wide angle, I didn't understand just how wide it is. If I do my non scientific calculations, 4x5 would have a diagonal of about 6.4". The distance from pinhole to film is approximately 3/4 inch. Hmm. I come up with about a 35mm equivalent 8.5mm lens. That is wide. In the images below: the camera was about 1" from the canon, in image 2 the tripod, camera (and me of course) were on the sidewalk, perhaps a foot and a half from the steps.
I learned that the free App is well worth 99 cents, it did a great job. I also learned through research that due to reciprocity characteristics TMax 100 (or Acros) are actually faster films than TMax 400 with very long exposures
I also need to triple check the built in bubble level before I expose the film.
