A Studio Flash Lighting
Auto white balance may not produce the desired results with large
studio flash units.
Use preset white balance or set white balance to
Flash and use fine-tuning to adjust white balance.
A Color Temperature
The perceived color of a light source varies with the viewer and other
conditions.
Color temperature is an objective measure of the color of a
light source, defined with reference to the temperature to which an
object would have to be heated to radiate light in the same
wavelengths.
While light sources with a color temperature in the
neighborhood of 5000–5500 K appear white, light sources with a lower
color temperature, such as incandescent light bulbs, appear slightly
yellow or red. Light sources with a higher color temperature appear
tinged with blue.
Note: All figures are approximate.
