Glossary
Parallax
: Changes in the apparent position and orientation of a subject when viewed from diff erent angles.
Point of convergence
: The point where the optical axes of the two lenses intersect and parallax disappears.
Smear
: A phenomenon specifi c to CCDs which causes white streaks to appear when very bright light sources, such
as the sun or refl ected sunlight, appear in the frame.
White balance
: The human brain automatically adapts to changes in the color of light, with the result that objects
that appear white under one light source still appear white when the color of the light source changes. Digital
cameras can mimic this adjustment by processing images according to the color of the light source. This process
is known as “white balance.”
