3 Introduction to Colour Temperature
Light has two main characteristics which have an impact on the work of the videographer, namely - ‘Luminance’ (intensity or brightness) and ‘Colour Temperature’. Whilst variations in luminance of light can be discerned by the naked eye, the human brain compensates for variations in colour temperature to ensure that we see the colour of objects consistently. Video cameras, however, will reproduce colours differently depending on the colour temperature of the predominant light source.
Colour temperature is measured in degrees Kelvin – with a lighted match producing around 1700°K . . .
