6. Color Modification Through Light
Under white light, a colored surface such as-
• green reflects only green wavelengths and absorbs
all others.
• A red filter allows only red light to transmit, which
mixed with a green surface appears black.
• Adding a colored filter to the white light changes
our perception of the colored surface.

While diffusion gels consist of
plastics similar to colored gels,
fabric diffusers are also an option.
You can use fabric diffusers and
colored photography gels to lessen
the intensity of studio lights and to
introduce colors and tones for
different effects.
Diffusers reduce exposure and
soften the light in varying
measurements, known as stops.
Purchasing diffusers in various
strengths is an easy way to add
more variety to light options in
your setup.
