any ideas on the best way to do this and get onsistent results, i.e. the same distance from the eye, she has an OMD with a few lenses plus access to an infinite number of OM lenses :-)

Olympus made a lot of really excellent macro/close-up equipment. Among it are 
three different close-up lighting options.

All are powered by a single model of power supply, and could be used with TTL, of the film auto exposure. For digital, you lose the TTL, exposure, but they may be set manually.

1. There's a straight ring flash, the T10. With the Ring Cross Filter Pol, direct reflections from the flash are suppressed, so it might be right for what Kerstin is looking to do.

2. A reflected ring flash, for very soft, flat lighting, the T8, which is supposed to eliminate ring shaped reflections for a shadowless image. <http://omesif.moosemystic.net/om-sif/flashphotogroup/t8.htm>

3. Small flash heads that mount on the lens, the T28.

With a fabricated thingie to rest on forehead, or some such, to regulate distance, T10 with Ring polarizer or T8 may well give good results.


my first thought is of some translucent tube with an on camera flash but I am sure the list members will have better ideas

CH's close-up flash adapter, or something similar, is another possibility.
