Re: "...Second, the film is required to be perforated on both sides..."

Filming upside down and then reversing it does not require the film to be perforated on both sides.

Say, you are filming a W with the camera upside-down and have 3 frames with the perforation on the left (each bullet in the list being a perforation). The film would look like this:

  • M I
  • M II
  • M III

Flip the film to reverse it:

  • W III
  • W II
  • W I


See the perforation is still on the left, the action is reversed, and the W comes out the correct way up. No need for two perforations.

Yes - the disadvantage is the film will be a fraction out of focus because the emulsion is, now, on the opposite side of the film. — Preceding unsigned comment added by 178.251.181.131 (talk) 10:18, 26 March 2015 (UTC)
