Glossary Of Film Making Terms - H



Halation – Halation is the effect that occurs when the bright areas of an image appear to softly bleed around the edges of dark areas. This is caused by light going through the emulsion layer, bouncing off the base of the film and exposing the adjacent emulsion. Some film is manufactured with a black anti-halation coating on the base side.


Half Apple – see Apple Box.


Halogen – This is the gas contained in the lamp of a Quartz Light, which prolongs the life of the tungsten filament. Quartz Lights are sometimes called Halogen Lights for this reason.


Handheld – Shooting without a tripod, but with the camera held by the cameraperson.


Head – 1.: The beginning of a shot or a roll is called the head. 2.: A small round clamp, usually used in conjunction with an arm on a C-Stand. 3.: The Tripod Head


Head Room – 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.


Hero Shot – 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.


Hi Hat – 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.


HMI – 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.


Hot Splicer – 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.


House Lights – 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.


Hyperfocal Distance – 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.
