3.2 Non-mydriatic photography/ autofluorescence photography procedures
This section describes the basic operation procedures for non-mydriatic and autofluorescence photography.
The operation of buttons explained in the procedures is based on the factory default. If the settings have been
changed, operate the buttons according to the modified settings. In order to photograph images with natural
dilation, dim the illumination of the room so that you may barely manage to read a newspaper (approx. 5 lx.)
