Infra-red Visible Ultraviolet
a normal photograph contains layers of three visible colors, red, green and
blue, and builds up a full color image of every shade the eye can see. an
extended spectrum photograph extends the spectrum into the near infrared and
near ultraviolet ranges, substituting UV for blue and IR for red. What you see
is a look into an extended world, where leaves are red and apples magenta.
