2.5.5 Low-light photography mode
In Low-light photography mode, the automatic ISO speed adjustment allows capturing of images of the usual
brightness with lower flash intensity than usual. It is useful for patients whose iris easily contracts. (Available
in Normal, Stereo, and Panorama photography modes)
The level of flash intensity lowered in this mode differs depending on the ISO speed of the internal CCD camera as
follows:
ISO100: Reduced 8 levels (about 1/4 of the specified flash intensity)
ISO200: Reduced 4 levels (about half the specified flash intensity)
ISO400: Not available
Setting for Low-light photography mode
Control menu: Photography settings—Photography Modes, Low-Light—ON (default)
When this mode is used (ON), the low-light photography toggle button is displayed in the screen. (When it
is not used [OFF], the button is not displayed.)
For details of setting, see “  Photography modes” (Page 111).
