COLOR OF LIGHT

Measured on Kelvin scaleNamed for physicist William Kelvin, who discovered a block of solid carbon emits light at specific colors depending upon the

temperature.

COLOR OF LIGHT

It is helpful to understand that what we call “White Light,” is actually comprised of all colors, at varying wavelengths.

Not all colors reflect off all surfaces, and not all colors transmit through materials.

How does color filtration affect B&W photography?

Selective darkening of tonal values based on color of the subject.

For instance, a red or orange filter on the camera while shooting black & white, will result in a darkening of blue and green tones, such as the sky, or foliage.
