Studio photographers rely on artificial light for their lighting needs. They have all sorts of artificial light sources in their studio kit, where the standard types are set up in the studio and the special ones are used only when necessary. The most commonly used artificial lighting in studio photography are the following:
Flash - Flash is the generic term for artificial lighting tools that produce high intensity and short duration light. It is usually balanced to daylight to achieve correct colour. Since it could reach short distances, flash is not considered as a continuous light.
AC Discharge Lamp - This type of lighting tool produces less heat compared to tungsten. But like tungsten, it has very high output. The light it produces is not continuous and it will guarantees correct colour when balanced to daylight. AC discharge lamps are mostly used in the TV and movie industry.
Tungsten-halogen - Tungsten light sources are next to flash with regard to the most commonly used artificial light. It emits light when the element inside the glass envelope is heated. Thus, tungsten-halogen heats up easily compared to other types of artificial light. It renders correct colour when balanced to tungsten. It will also not discolour after several years and will maintain correct colour balance. Tungsten light sources are usually used as spotlights.
Photoflood - In terms of design, this type of artificial light is similar to typical domestic lamps. It doesn't require colour correction and the type of light it makes is balanced to tungsten. After several years of usage discolouration could manifest around the glass surrounding the element. If that happens, an orange colour cast will be evident particularly when balanced to daylight. This deficiency in colour can be corrected either by using a blue filter or by post processing the picture. Photoflood is used to create a broad soft light source.
Light meter is also an essential studio photography lighting equipment. Without it, photographers will find it difficult to know the relationship between light ratios and exposure. For this reason, light meter is considered as the most important equipment (next to camera) a photographer will own.
