1/250th

White (255)
24 bits per pixel (8 per color) - which gives 16 -777 -216 colors
a sensor (or film's) sensitivity to light
Parallax

3. What does "photomacrograph" or "macrophotograph" mean?

The impression human vision gives
Also called a gobo; it is a small panel usually mounted on a stand that shades some part of the subject or shields the lens from light that could cause flare

7. What is a BYTE?
