Will the shadows be ok when using a flash from only one of the cameras?
Moderate stereo bases, 7 - 14 cm, and subject within 4 - 15 m, assumed.

Thanks.

The flash for the Fuji Real 3D W3 is located between the two lenses. If the subject is close to a wall you see a dark shadow on the right side of the subject in one image and on the left side in the other image.  When viewing the image in 3D you can get a sort of shimmering effect with the shadows.  If you place the light above one of two cameras in a 3D rig you will get fewer strange effects but it would be best  to get the flash completely off the cameras.

The best way to use flash is to use it off-camera in a position that simulates more natural lighting, i.e. light from the sun. If you look at most portraits you will see the catchlight is from a light oriented above and about 45° to the side.

If you have a way of firing your off-camera flash with your 3D rig then these tutorials can help you learn how to use your flash. Whether your camera is 2D or 3D won't make any difference.
