Shel Belinkoff:
What are "quantization effects?"
The effect that comes from that you only have distinct levels to play with, and that subtle changes have to be either on or off.
Assume 8 bit gray scale. That means 256 distinct shades of gray from 0 (full black) to 255 (full white).
A change from one shade to the next, say from level #240 to #241 is very small in percent, but if you go from shade #1 to #2 it's a 100 percent increase.
