I must differ totally with the person who's telling us to use a 12 frame loop with the ACL's.
The NPR is 12 frames.
The ACL was designed differently.
I was in the manufacturing plant both in France, and later, in England.
I was trained in both places.
We were instructed to bring the film out and around the pressure plate area.
The next step was TO PULL THE LOOP TO THE TOP OF THE MAGAZINE..STRAIGHT UP.
THEN LET IT GO AND BALANCE IT OUT.
THEN LEAVE ONE MORE FRAME ON THE BOTTOM ON THE BOTTOM PART OF THE LOOP...
IN OTHER WORDS, IMBALANCE IT BY ONE FRAME ON THE BOTTOM.
THERE IS NO WAY THAT WOULD EQUATE TO 12 FRAMES.
I NORMALLY END UP WIYH 14 FRAMES.
THE REASON FOR THE EXTRA FRAME ON THE BOTTOM WAS THAT, IN THE EVENT OF FILM BEING LEFT IN THE MAG FOR AN EXTENDED TIME PERIOD...A DAY OR TWO BETWEEN TAKES, THE PLASTIC, OF WHICH THE FILM IS COMPRISED, WOULD DEVELOP A "MEMORY".
IT WOULD WANT TO TEND TO REMAIN IN A LOOP-CURVED POSITION.
THIS WOULD TEND TO GIVE IT AN OPPORTUNITY TO LOSE A FRAME ON THE LOOP.
BY PROVIDING THAT EXTRA FRAME ON BOTTOM, YOU WOULD STILL REMAIN BALANCED.
