O.C.N. - O.C.N. stands for
Original Color Negative. It is simply your developed negative.
180° Rule - This is the rule which states that if two
people are filmed in a sequence there is an invisible line between them
and the camera should only be positioned anywhere within the 180 degrees
on one side of the line. Crossing the line results in a certain particular
jump, where is appears that the two people suddenly switched
places.
One Light - The alternative to a Timed
Print, a one light is a print that has not been corrected shot by
shot, but shows what all the shots look like with the same printing lights
in contrast to each other. Sometimes this can be helpful to know the range
of fluctuation in exposure and color. (But it is curiously common for a
lab to do some timing, even on a one light print, at the change of
locations, at the change of rolls, or if one shot is so drastically off
from the rest and it would be practically unseeable otherwise.)
Optical Printing - Basically, rephotographying
film frame by frame. this is a way to make a copy of a film with many more
possibilities than contact printing, but, at least with 16mm, resulting in
a little added contrast and a little loss of
clarity.
Optical Track - An intermediate step from going
from your mix master to your final print is to have an optical track
struck. An optical track is photographed onto a blank piece of special
high contract stock by the facility where the mix is done, or by the lab.
The optical track is a separate roll of film from the original negative
and is combined with picture when a print is struck. (The track itself
still remains a separate element from the A&B Rolls, it is printed in
a separate pass through the contract printer.)
Opticals - Effects produced through Optical
Printing, including transitions, superimposed titles, etc.
Sometimes called Optical Effects. However, anything optically
printed can be called an optical, so even blowing film up from 16mm to
35mm, though it does not involve an effect, is an optical.
Orange Stick - An orange stick is found at the
drug store for cleaning your nails. It is the preferable way to clean the
gate.
Original - Any film, negative or
reversal, that was shot by a camera, as opposed to a print or intermediate
copy. The term original can be used interchangeably with negative, but is
as especially handy term when taking about reversal film, where it is the
clearest way indicating whether something is a dupe or the
original.
Outdated Stock - Film is
perishable. When it starts getting stale the dyes will shift color and the
grain will build up, giving you a generally fogged, muddy and desaturated
effect. It is only after about 2 or 3 years that this will start to
happen, provided the film is refrigerated. Faster films tend to become
outdated slightly faster than slow films. Likewise, color film will become
outdated a little sooner than black and white. The flip-side is that
outdated stock can be gotten quite cheaply, and often for free.
Outtakes - The footage from your workprint that is
not used in your edited version. Very small bits, a few frames or as
little as one frame, are known as Trims.
Overcrank - To run the camera faster, producing slow
motion. The term has survived from the time when you would crank a
camera.
Overexposure - Filming a scene with
more light than the emulsion of the film can easily tollerate. The image
will be too light and there will be less depth of field than if the lens
had been set correctly. If compensated for in printing, the image will
appear contrasty.
