Preset White Balance Settings VIDEO Camera Guide
Ambient light is an existing natural or artificial light present in any environment. Ambient light can be subdivided into four major categories:
Daylight DSLR Camera
Is a mixture of sunlight and skylight. Sunlight is the dominant or main light. It is warm in colour and creates highlights and shadows. Skylight is the secondary light. It is cool in colour and fills the entire scene with soft diffused light. Without the action of the skylight, shadows would be black and detail would not be visible.
White balance is usually calibrated to daylight at noon (5500K). When images are recorded at this time of the day the colours and tones reproduce with neutral values, i.e. neither warm nor cool.

Tungsten Camera Option
A common type of electric light such as household bulbs/globes and photographic lamps. A tungsten element heats up and emits light. Tungsten light produces very warm tones when used as the primary light source. Underexposed picture occurs due to the lack of blue light in the spectrum emitted.
Digital cameras can be set to automatically adjust the white balance to correct the colour cast from light sources of different colour temperatures or this can be set by the photographer by choosing either a white balance setting or creating a customised white balance setting (see Colour Correction and Filtration > Colour accuracy in-camera).
Phosphors inside fluorescent tubes radiate light after first absorbing ultraviolet light from mercury vapour emission. Resulting light from most fluorescent tubes produces a strong green cast that can be difficult to correct and is not apparent to the human vision. If used as a primary light source the results are often unacceptable due to the broad flat light and the strong colour cast.
Daylight balanced fluorescent tubes and compact fluorescent lamps are available and these are increasingly being used as a photographic light source.
Light from naked flames can be very low in intensity. With very long exposures it can be used to create atmosphere and mood with its rich red tones.
