The purpose to change the Threshold Level in the Photo Mode is to make all copy images evenly
darker or lighter.
Whenever you select larger Threshold Level, all copy images become evenly darker.
Whenever you select smaller Threshold Level, on the contrary, they become evenly lighter.
Note : All images of original are taken as “necessary image” in the Photo Mode because the purpose
of the Photo Mode is to re-produce all images of original and their density gradation faithfully.
Even if you change the Threshold Level in the Photo Mode, all images including extremely
light image are surely read and copied.
Therefore, select the Photo Mode if you copy a photographic original.
