Martin,

There are several tricks to avoid flash refection, but no magic.

In order to avoid reflections, light is bounced from flat surfaces such as
walls, mat board, etc.
The light is diffused at the source by placing diffusion material such as
frosted plastic, white cloth, or paper, in front of the flash (the farther
from the flash the more the diffusion).
The strobes are aimed at such an angle that the lens will not see the flash.
Try using a Nikon F3, it has an off-axis flash connection thus avoiding the
angle of incidence (I could not resist that one).

Avoiding the angle of incidence is fairly easy when the subject surfaces are
flat. When they are curved some degree of reflection is unavoidable.

Hope this helps clarify the issue.

Joe C.
