barn doors

(Last edited: Tuesday, 30 July 2013, 5:41 PM)
Barn doors are an attachment fitted to the front of lights used in films, television, and theatres.

The attachment has the appearance of a large set of barn doors, but in fact there are four leaves, two larger and widening on the outside, two smaller and getting narrower towards the outside. They facilitate shaping of the beam of light from the fixture, and prevent the distinctive scatter of light created by the Fresnel lens from spilling into areas where it is not wanted, such as the eyes of audience members. Barn doors are mounted with a ring that fits inside of the colour gel slot on the instrument. Because of this, barn doors have a gel slot built in to them, so the light can still be coloured. Depending on the size and local practices, barn doors may be attached to the pipe or the instrument with their own safety cable.

gel

(Last edited: Tuesday, 30 July 2013, 5:41 PM)
A colour gel or colour filter, or a lighting gel or simply gel, is a transparent coloured material that is used in theatre, event production, photography, videography and cinematography to colour light and for colour correction.

Modern gels are thin sheets of polycarbonate or polyester, placed in front of a lighting fixture in the path of the beam. Gels have a limited life, especially in saturated colours. The colour will fade or even melt, depending upon the energy absorption of the colour, and the sheet will have to be replaced. In permanent installations and some theatrical uses, coloured glass filters or dichroic filters are being used. The main drawbacks are additional expense and a more limited selection.

180 degree rule

the continuity approach to editing which dictates that the camera should stay on one side of the action to ensure consistent spatial relations between objects to the right and left of the frame. The 180-degree line is also called axis of action.

For example filming a conversation requires that the placement of the camera should not present the two speakers in such a way that they both look to be talking towards screen left (or both talking towards screen right) when they should be seen talking in opposite directions
