Nikon SB-16 instruction manual Red Eye, Soft Flash Unit Case 55·16

Soft Flash Unit Case 55·16

The SS-16 accommodates the main flash unit of the S8-16 and both Flash Unit Couplers AS-8 and AS -9, one at- tached to the main flash unit, and one stored separately inside the pocket, with the Wide -Flash Adapter SW-7 attached to the flash head. If you do not store a flash unit coupler in the pocket, then you can put the SW-7 inside the pocket instead of attaching it to the flash head. The pocket can also be used to store spare batteries.

Note: In storing the coupler or adapter inside the pocket, never put them together or anything else with it. If you do so, the electrical contacts on the mounting foot of the coupler or the glass surface of the adapter may be damaged.

"RED EYE" ------

"Red eye" is a phenomenon in flash photography where the center portions of the subject'seyes appear as bright red orbs in color photographs (or white in black and white pictures). This is a result of the light from the flash illumi - nating the retina directly. If the subject looks straight into the lens and there is little or no ambient light, the pupil is wide open , making the retina clearly visible in the picture .

To avoid "red eye," you can take any or all of the follow- ing precautions :

1.Ask the subject not to look directly into the lens when the picture is taken .

2.Remove the flash unit from the camera and hold it as far away as possible from the camera by using a sync cord.

3.Increase the room'soverall illumination to reduce the opening of the subject'spupils.
