The biggest difference between Caiman and Alligator or Crocodile leather is that the Caiman leather is not near as durable. A Caiman fuscus crocodile have small bony plates â if you bend the leather across these plates you will see that the leather creases between the scales.
According to IMAX, 35mm film has a digital equivalent of 6000 lines of horizontal resolution (6K), while 70mm film has the equivalent of 18,000 lines of digital resolution (more like 12,000 in reality).
You can't currently get that resolution from a digital camera/projector). Interstellar, and many of Nolan's recent movies, have sequences actually shot on IMAX 70mm film cameras. Those are the highest resolution images possible, and look absolutely stunning when projected on a true 15/70 IMAX film projector/screen.
