Lab Roll - A large roll
(usually up to 1,000 feet) made up of camera rolls joined together by the
lab for printing.
Latent Edge Numbers -
Precisely, the edge numbers, and not inked-on code numbers. see Edge
Numbers.
Latitude - The degree to
which a certain film stock can tolerate under- or overexposure. Reversal
film, for all practical purposes, has a very little latitude. Color
negative has a higher latitude, and particular of its latitude it is
tolerant of much more overexposure than underexposure.
Lens Flare. It is caused when light strikes the
lens and either causes the entire image to be fogged in appearance, or for
a little row of polygons (the silhouette of the iris) to appear from the
light hitting the surfaces of the many elements in the lens. It is solved
by flagging the lens.
L.F.O.A. - This stands
for Last Frame of Action, and basically it is just what it sounds like:
the last frame of image and sound on a reel. It is important to the people
who mix your film (it should be written on the cue sheet), especially if
you need to do Pull
Ups.
Lights - see Timing
Lights.
Lightleak - Stray light
that penetrates into a camera giving the film little patches of fog. Also
the term for the access point itself. Typically light leaks occur around
the camera door or where the magazine is joined to the camera body. Often
they can be easily prevented with camera tape around the door.
Lip Sync - Another way of saying Sync
Sound.
Loading Booth - A small
darkroom sometimes found on a sound stage for loading film into magazines
as a roomier alternative to a Changing
Bag.
Location Sound - This is
the sync sound, or any other sort of wild track or room tone that was
recorded at the shoot. Same as Production
Sound.
Locked Cut - The so-called
final cut of a film when there are to be no more changes to
picture.
Locked Down Shot - A shot taken
with the pan and tilt releases on the tripod tightened so that the camera
will not move. Often done for certain effects where camera movement would
ruin the illusion, such as a cut that causes a character to magically
disappear from a scene.
Long Lens - A lens
with a focal length greater than 25mm in 16mm, or 50mm in 35mm, which,
like binoculars, will provide a view that magnifies a small
area.
Loop - 1.: Slack film above and
below the gate to allow a transition from the constant motion of the
supply and take up rollers to the intermittent motion that takes place at
the gate. 2.: A small magnifier useful in the editing room.
3.: see Dubbing.
Looping - see Dubbing.
Called looping because the film is on a loop to give the actor several
tries at a line. Also called A.D.R.
Low Con Print - A low contrast print specifically for
transfer to video, which favors less contrast in the transfer
process.
