Hi Everybody,
Recently I got interested in the possibility of
creating Virtual Reality panorama's that can be
viewed on a computer using either Apple's (free)
QuickTime Player, or just plain Java (inside a
web browser). For samples, look here:
<http://homepage.mac.com/sander.schrieken/QTVR.html>
Rather than taking a series of photographs
covering the full 360 degrees of the panorama and
stiching those together using the appropriate
software, I decided to go with the EyeSee 360.
Essentially a parabolic mirror which reflects
everything surrounding the camera into the lens,
for a visual of the apparatus look here:

Since I am not yet ready to buy a new (digital)
camera I want to use this device with my OM-F
(OM-30) and zuiko lenses. Sadly however, my first
efforts haven't brought the desired results...
I've been experimenting with the 28 mm (f 3.5)
and the 50 mm (f 1.8) [using the highest possible
f-stops in order to maximize depth of field] to
try and maximize the image of the mirror on the
film. The bigger the image, the higher the
resolution -- especially after scanning.
I suspect that I haven't used the right lenses,
because the image of the mirror covers only one
third of the hight of the film...
***** What lenses and/or extension tubes would
give the best results? *****
Underneath is an excerpt from the EyeSee manual.
Note that the distance between subject and camera
must be between 9 and 18 inches. The required
depth of field is 2 to 3 inches.

Hopefully someone on this list can point me in
the right direction. Any advice is welcome!
