When the color temperature of multiple

light sources are equal (or very close),
the actual color temperature being
illuminated needs to be measured for
correct digital or film measurements and
subsequently accurate color
reproduction. Take a measurement by
placing the color meter at the position of
the subject with the light receptor facing
towards the camera's lens axis.
Note )
@It's common for a subject to be illuminated by reflected light from its surroundings, as well as
from the main source of light. It is recommended that measurements be taken from the subject's
position in these situation. If the main light source is more pronounced than the reflected light,
measurement should be taken closer to the main light source with the light receptor pointed
towards the light.
@Try to minimize the influence of the person taking the light measurements. (Do not obstruct the
light sources. There will also be reflected light from the person's clothing, so do not allow this
reflected light to enter the light receptor.)
@Because it may affect the precision of the measurements, be careful not to damage or dirty the
light receptor(flat diffuser). If the light receptor becomes dirty, wipe it with a dry, soft cloth.
Never use organic solvents such as thinner or benzene.
