Stitcher Unlimited & Canon 10D & Sigma 8mm

Here are my observations on the workflow to use Realviz Stitcher 5.5 U and the Canon 10D and Sigma 8mm lens setup.
I'm very interested in this because even though my current setup uses the Canon 5D a large number of my exhibition prints ( were produced using my old canon 10D.


Capture - the usual manual focus, manual exposure, manual white balance and six photos around and one up.
Stitching -
1) Launch Stitcher Unlimited and load the 7 photographs, Stitcher spots that they are from a circular lens and offers initial settings, accept these.

2) Rotate the 7 photographs CCW
3) Go to Properties

4) Calibrate Fisheye lens, adjust the circle till happy, press Okay

5) Properties slightly changed for the better.

6) Press AutoStitch and wait a short while

7) Before render I suggest you stencil out some of the overlap at the zenith, I basically removed the top section from each of the six photographs around which overlap a lot with the zenith shot.
8) Setup Render for a Spherical Image. Strangely on my computer even though I have Smart blend the Stitcher software shows ext-Blended - this doesn't help matters, especially since external blending fails to start when that options is chosen. So it is wise to check which option you have selected - as shown in the second image below. This doesn' happen on my Windows PC.

Sadly this takes a very long time on my Apple Mac OS Dual G5 2 Ghz computer, the smart blend stage is very slow and you can see this has taken over 20 mins. to get to this stage, my Dual Core Dell laptop was showing 5x speed increase over this............

9) Take the resulting .TIF into Adobe Photoshop for any extra adjustment, in this case I just sharpened a little.
10) Process the .TIF through CubicConverter followed by Pleinpot to generate full-screen QTVR panorama.
The result is here and has worked well.
Enjoy, the historic Oxford Covered market.
