Exploration of the Principles of Lighting

In this report I will be explaining the major and minor principles of lighting, the purpose of key, fill, black and background lighting along with the purpose of high and low keylighting. I will also be including detailed diagrams of two scenes from a film I have worked on.

The more modern day purposes of lighting are in particular for it to create a sense of realism. Along with this modern day lighting emphasizes colour, reflection and atmosphere. In the earlier days of film it was necessary to use extreme amounts of lighting. This was because earlier film …show more content…

This was the main reason for the lack of sensitivity to light.

Film speed is measured in ASA numbers. The higher the ASA number, the faster the film's speed and the lower amount of light needed to create a picture.

ASA speeds vary all the way from 10-2000 ASA. Early film used around a 10-50 ASA whereas modern films use around a 200-300 ASA which of course affects how much light is need. These are the following ASA speeds:

â— 10-50 ASA - Early film, needs a lot of light.

â— 100 ASA - Outdoor photography and indoors with flash.

â— 200 ASA - Outdoor photography and bright indoors.

â— 400 ASA - Outdoors and indoors, no flash needed.

â— 2000 ASA - Highest speed possible with no light needed but results in a grainier resolution.

The major downfall with using a higher ASA in film creating is that the finished picture will have a much grainier resolution then a film using a lower ASA.

There are problems with both ASA extremes (i.e. 10 ASA & 2000 ASA) which means that a compromise must be made somewhere in between …show more content…

Film and equipment has changed throughout the ages and higher film speeds have since been created to make film making more practical.

Modern domestic video cameras along with professional equipment are very sensitive to lighting yet lighting is still used. The following information will provide an explanation as to why we still insist on using lighting.

Movie lighting produces depth, shape and texture in a medium which is essentially flat and two dimensional. It also can indicate to the audience which time of day it is or what season it is.

There are a few other major purposes of lighting, one of these being its ability to create a sense of realism. For example a particular scene could be filmed with the lighting coming from the side of the window, which in affect would seem like the sun shining through the the viewer. Other major benefits to lighting are that it works well in emphasizing colour and reflection. Atmosphere and mood is another thing affected by lighting in a film; for example a Tim Burton
