Light in Photography - Visible
Light - lies
in the narrow band of wavelengths from roughly 400 to 700 nm. One
nanometer is 10-9 or one millionth of a millimeter. Within this range,
the wavelength determines the colour of the light we perceive, beginning
with violet at the shortest wavelengths and proceeding through blue,
green, yellow and red.
the red end of the visible spectrum lies the invisible infra red region
and wavelengths shorter than violet are called ultra-violet, also
invisible. Remember that while we only see light - film and some digital
cameras are capable of recording UV and Infrared- we even have X Ray
film - so it is important to remember that what we see and what the
camera records might be different.
travels through space at 186,000 miles a second and
it takes 8 mins for the light of the sun to reach the earth.
I worked on a project titled @
the Speed of light.
