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).
The advent of low-grain 35 mm film stock and digital soundtrack systems led to a decline in 70 mm use in the 1990s, and few 70 mm films are made today. A horizontal variant of 70 mm is now used for IMAX films. The speed (sensitivity) of the film stock also affects the quality of the image in projection. Slow film stock is less sensitive to reflected light, so brighter light sources are necessary during shooting to produce sharp images.
