EXPLORE THE PROPERTIES OF LIGHT
For photographic purposes, light possesses several properties. The first is intensity, which will be discussed later. The second is colour, which in photographic terms is measured by colour temperature. This temperature scale is based upon the concept of a ‘black body radiator’. In essence, this means that if we take, for example, a cold black iron bar and heat it, we will eventually reach the point where it begins to emit light. The temperature required to make this body emit light is measured in Kelvin degrees, the scale of which begins at absolute zero or minus 273 degrees C.
Consequently, the light emitted by a tungsten light source (for example, studio flood lights), is said to have a colour temperature of 3,200 degrees or the equivalent in light spectrum emission to a black body radiator heated to this temperature. The higher the temperature, the bluer and less red the light emitted until eventually, at very high temperatures, the light moves towards the violet end of the visible spectrum. Normal daylight is measured to be 5500K degrees.
Colour Temperature
is important in colour photography as film is manufactured to give accurate colour images based on this system of measurement. Tungsten film will produce false colour in daylight and vice versa. Some sources of light (eg. Fluorescent tubes) produce light through the injection of electrical energy into an excitable gas. Such sources are given a value called a correlative colour temperature. Since the gas does not behave as a black body radiator, the value cannot be seen as having the same reliability, since these types of light sources do not give a consistent colour output and can include spectral spikes which cause colour casts with some films.
Incident or Reflected Light
The other two major properties of light are whether the light is incident or reflected. Incident light is measured from its source as it lands on or hits the surface of a subject. Reflected light is the light that comes from a surface, or in other words, the incident light measured as it bounces off the surface of the subject. In general, incident light readings for photographic purposes are a more accurate manner of determining correct exposure than reflected light readings. However, there are obvious situations (eg. landscapes) where it is impossible to take an incident reading due to the scale of the subject being photographed. In these cases, reflected readings are our only options.
Lighting is a critical factor in photography. Light sources can be defined in terms of four properties:
- Colour Temperature
- Power (or Brightness)
- Size
- Prevailing Direction
