[photo-3d] re:Thanks for info(stereobase)

["Steve Boddy" <s.boddy@xxxxxxxxxx>]

Thanks to Sergio and Mark for the stereobase info.The drawing
explained things very well,and the different sizes are very
interesting.I have constructed three prototypes for use on a
digital nikon coolpix 990 and because i spent more time
trying to line up the mirrors i had not taken into account
the stereobase. After measuring,they all seem about
the sizes given (70-100).
Still can't get to grips with the alignment of a tri-delta which
i am also trying to construct,i will carry on with it though and
maybe i will get there in the end. 

thanks
      Steve.
