Funny.  I originally thought it had a clear center  strip also, but on
further inspection, it appeared that pushing the switch all the way into
Q-dos position eliminated this.  In other words, the two filters folded in
from opposite sides of the lens barrel, and you had to make sure they met
in the middle by pushing the switch all the way.  At least, that was my
impression at the time.

So, do you think a home-made red/cyan lens might work better then the
Q-dos?  I haven't seen any results for comparison, but I know a few people
on the list made some a while back.  How were they?

Thanks,
