Studio photographers utilise artificial light for their photography lighting needs. They have different types of artificial lighting in their studio kit, where the basic lighting kits are set up in the studio and the special lighting kits are used only when necessary. The most commonly used artificial light sources in studio photography are the following:
Flash -It is a term for artificial lighting devices that are of high intensity and short duration. It is not considered a continuous light since the light it emits could reach only short distances. Achieving correct colour using this light source means balancing it to daylight.
AC Discharge Lamp - This type of artificial light source has a very high output and emits less heat compared to tungsten. Like flash, it will render correct colour when balanced to daylight. It is also not a form of continuous light and the design of the light is almost similar to the tungsten-halogen spotlight. The film and TV industry usually utilises this type of artificial lighting tool.
Tungsten-halogen - Next to flash, these types of light sources are the most commonly used artificial light. It heats up easily because it could only emit light when the element inside the glass envelope is heated. This light source renders correct colour tone when it is balanced to tungsten. Also, it will not exhibit discolouration despite years of usage.
Photoflood - The design of this type of artificial light is similar to typical domestic lamps. It doesn't require colour correction and the type of light it produces is balanced to tungsten. Throughout time 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 produces a broad, soft light.
Having the right lighting tools however is not enough to achieve proper exposure. Photographers also need light meter in their studio kit so they can determine the right amount of light to use, allow, and block. Only light meter can tell exactly the connection between lighting ratios and exposure.
