pair? I have two cameras to use with my two different lenses, but
thought this would be unusable for stereo panoramas. Or do you mean
you have a pair of Canon 5Ds AND a pair of Canon EOS450s? With
matching lenses? If so, WOW! I have a Fuji S5 Pro and Nikon D300.

enough to affect the 3D output. I do always try to remove them at
the RAW image level...

the 3D images. The first ones I had looked at must be among the least
affected, the least "ugly." I see now that there is not a great deal of
difference or advantage on either side. I was hoping I could sell my
clients on using ColorCode 3D by telling them non-stereo viewing would
not be significantly degraed but I see that this is untrue. Too bad!
Thanks for the helpful reply, Wim. When their webshop spring cleaning is
done I will get the Windows PC software.
Using a bar with two cameras necessarily means that both cannot be
revolving about their non-parallax points. Do you find that greatly
affects stitching, generating errors in the final panorama?
