WE’VE LAUNCHED A NEW SCREENWRITING PROGRAM | VIEW PROGRAM
The space between the top of a subject’s head and the top of the frame. Headroom must be carefully apportioned so that there is not too much or too little, especially if shooting for transfer to video or for blowup, where the frame will be cropped in a little on the top and sides.
Often used in sports coverage. For instance the closeup of a person who just made a score in a basketball game is called a hero shot.
This is a square of plywood with a bracket attached, to which a tripod head may be added (or is sometimes permanently affixed) used for filming with the camera very low to the ground. Its name is a bit of a contradiction, to its use nowadays, but it used to be that a Hi Hat was for shooting from very high up, with the plywood board being mounted up high somewhere.
This is a type of light. HMI stands for Halogen Metal Incandescence. HMIs are very bright, power efficient lights. They are balanced for the Color Temperature of Daylight, making them handy in mixed lighting situations. However, they are rather expensive, costing something in the few thousands of dollars, and are not very portable due to the large and heavy ballast that is attached. Also, and this is vitally important to keep in mind, they must be used with a Crystal Sync camera, otherwise they will flicker and throb.
A Cement splicer with an electric heater inside. The heat improves the bonding of the cement splice. Hot splicers are really not dangerously hot, just warm.
You can request “House Lights” for a print and the lab will not time your film, but print it without any exposure or color correction. House lights are typically at the middle of the printing scale: 25 – 25 -25.
The hyperfocal distance is a distance set on the focusing ring of the lens that will most efficiently use the Depth of Field present. A depth of field chart will list possible distances and graph out the area of focus at different f-stops. There does not necessarily have to be a subject to focus on at that distance.
The equivalent of A.S.A. and I.E., just with another name, it is another way of saying the same thing. This is the least frequently used of the three, but is sometimes found on the light meter. Treat it just as if it was A.S.A. I.S.O. stands for International Standards Organization.
An incident light reading measures the amount of light hitting the subject. You take an incident reading with a light meter equipped with a white half-sphere which acts as a stand-in for the subject. The sphere is pointed at the camera, so that the same light hitting the subject is hitting the sphere. The other type of light reading is a Reflective Light Reading.
The furthest distance on the focusing ring of a lens.
A close-up of some detail in the scene. (Sort of like a cutaway without the “-away” aspect.)
Two or more devices (most commonly dubbers in a mixing facility) with motors that run in sync are interlocked. It is not quite correct to say that a sync sound camera and tape recorder are interlocked, regardless of whether they use crystal of cable sync, since the tape recorder is recording pilottone and not really running with its motor interlocked with the camera motor.
An intermediate copy of a film, made on a very fine-grained stock, and used to make a greater number of prints than it is practical to make from the A&B Rolls.
An intermediate copy of a film, made on a very fine-grained stock, usually required as an intermediate step to making an internegative.
A device that attaches to the camera for filming single exposures, much like an animation motor, exept that an intervalometer is capable of exposing single frames automatically, as in the technique of Time Lapse photography.
