[Function]
Contrast is set for each mode.
When this simulation is executed, the current se value is displayed in 2 digits (Default: 50).
Change the set value and press [START] key to make a copy under the set value.
When the set value is increased, the contrast becomes higher. When the set value is
decreased, the contrast becomes lower.
In this case, only Exp.3 copy is made. When, however, the setting is made to make higher con-
trast, Exp.1 and Exp.5 copies also become in higher contrast. When made to a lower contrast,
Exp1. and Exp.5 copies become lower contrast, too.
Press [Exposure mode selector] key (or [
