Open- Flash Button @
The ready-light on the SB -16 can be used as an open- flash button to fire the flash unit manually without having to trip the camera 's shutter. In this manner, you can create multiple-exposure "stroboscopic" effects or paint the scene with light by firing the flash unit repeatedly with the camera set at B. In this case, make sure that the flash unit is not connected to the camera.
The open-flash button is also useful for test -firing the SB-16 to determine whether the illumination from the flash was sufficient for proper exposure in the non -TTL automatic mode. With the shooting mode selector set at one of the color-coded dots (A1 or A2), push the" FLASH" button; if it starts blinking, then you know the amount of light might have been insufficient for the subject. In this case, reset the selector to A1 if it was set at A2, or move closer to the subject. This test-firing is especially useful when the flash head is tilted and/or rotated for bounce flash.
