Re: [PanoToolsNG] Stereo-3D Anaglyph Panoramas
- Hello Roger,
I will try to answer your qustions.
(1) How do you take the stereo panoramas, with two cameras on a bar?
And a followup question. For scenes with no movement, would it
be possible to move a single camera along a bar to take the second
series of images?
A1) I shot the images with 2 cameras mounted on a bar that is mounted on a
Seitz VR drive, a Canon 5D+shaved Tokina 10-17@12,4mm and a Canon
EOS450D+Sigma8 f3.5. The stereobase is approx. 82mm.
With one camera it only takes more time, and it is a little more difficult
because you must be very carefull not to move the tripod but is very well
possible. The advantage of using one camera is the fact that the stereobase
can be set to a smaller distance so it is possible to shoot closer to
(2) I notice that the stereo effect is perceived by those (like
myself) who do not yet have the amber/blue stereo glasses as
purple fringes. I shoot with either a Sigma 8mm or a Nikon 10.5mm
fisheye, and sometimes I get stubborn purple fringes that are
nothing to do with stereo vision (!). Would this make it difficult
for me to get a good stereo effect?
A2) I always remove CA and fringing in the source images (with Adobe Camera
Raw) and what is left is not giving any problem in the 3D output.
(3) Also the dreaded Acrobat 9 bug prevented me from viewing the PDFs
with detailed information and pricing, etc., in my browser. What do
they charge for the software to create 3D images?
A3) There are several ColorCode 3-D applications, the one I use "ColorCode
3-D Editor 4 PC" costs 69 euro including VAT. There is also a Mac version
but this app is not suited for large images (I tried it and the helpdesk
confirmed that is only suited for small images) and therefore I run the PC
app in Parallels with XP on my MacBookPro.
Apart from the purple fringeing, I thought that ColorCode 3D images
were much better than red/cyan analglyphs for people who come
across them without stereo glasses.
A4) In theory this is true, in practice it depends on the shift of farpoints
between the left and right images, when the shift is small then indeed the
images are, compared to red/cyan anaglyphs, better to look but when the
shift is large they are just as ugly without a viewer (take a look at the
stereo base distance comparison at 10 mm and 62 mm and it is clear what I
