Chapter 9 Pattern

English

The right half-moon pattern is assigned with a grayscale 2 levels higher

than the square; and the left half-moon pattern, 2 levels lower. The

upper left and lower right patches, 4 levels higher; and the upper right

and lower left patches, 4 levels lower.

This pattern is mainly used to check the grayscale characteristics, but it

can also be used as a simple check of the viewing angle characteristics.

Watch the pattern from different angles. The viewing angle is the area

where you can identify all the half-moon patterns.
