Re: [tech-3d] Re: Stereo Base Calculation With a $20.00 Handheld

Michael:
   I only do 3D video, no photo. Some months ago I purchased a HP 48G+
and programed it with the same formulas you did. I have twitched them a
little to accommodate for different size CCDs in different types of
cameras and the "on film deviation". Your approach, very similar, to
mine has worked perfectly for me. Please visit vrex.com for an
interesting approach to the camera separation subject in a white paper
called "Rendering Stereo Image Pairs".
