Standard TTL Flash

In this mode, although exposure for the background is metered by each metering system, flash output level is not determined automatically. However, you can manually select flash output compensation (on the 88-24) at levels from +1 to -3 EV, for greater personal creativity.

-The usable film speed for TTL flash photography is 180 25-1000; for non-TTL flash photography, it is 6-6400.

-For details on speedlight operation, see the speedlight instruction manual.

-Use Nikon 8peedlights. Other units may damage the camera'selectrical circuit due to incompatible voltage requirements, electric contact alignment or switch phase.

-When using a special speed light with a time-lag provi- sion or when using a speedlight with a long flash du- ration (Le., Medical-Nikkor 120mm 1/4), adjust shutter speed down to 11 125 sec. or slower.

-When using a speed light that does not allow automatic sync speed setting, set the camera'sexposure mode to Manual.
