3-3 Mydriatic color photography
This paragraph describes a method of mydriatic color fundus photography. Reduce the room’s luminance as low as
you can barely read a newspaper.
1) Select “Color” by the mode select button on the right-hand panel.
2) Adjust optical viewfinder diopter.
Turn the optical viewfinder to a full range of plus (+) side.
Then slowly turn it clockwise while looking into the viewfinder
and stop it when the double line comes clearly in sight. If the
diopter is incorrect, the result is that the picture will be out of
focus. If you wear glasses, look into the viewfinder with its rub-
ber adapter turned up.
