Daylight is fundamentally a cool light with tones that lean towards blue. Artificial light such as a candle or a household tungsten bulb are much more orange in colour and are often referred to as warm lights. Light is measured scientifically in 'Kelvin' using the visible light portion of the electromagnetic spectrum. So, the cooler the light in colour, the higher the number in Kelvin, daylighttherefore is normally measured as 5600K. The warmer the light in colour, the lower the number in Kelvin so a household tungsten bulb, for example, is measured as 3200K.

The digital camera has the ability to set a colour balance and this is measured in degrees Kelvin. So, a daylight camera colour balance is 5600K and a tungsten camera colour balance is 3200K.

Once you understand WHAT it is you are trying to create, you can then look at the HOW to achieve it. That then moves you to consider what the most effective tools will be to 'create' your lighting setup.
