Yeah, depending on the focal length, I guess rotating camera images look much alike.  Is there an digital equivalent to the Larscan idea?  One that a person can make at home, that isn't too cumbersome and doesn't require a car battery to run it?  I assume anything made by Seitz is very expensive.

On the electronic front there are several models being manufactured/marketed. Spheron (sp>) is one ... the Better Light scanning back device can be accessorized with a turntable and become a real high end digital pano camera ... and there are several others ... Seitz also makes one ... it is hard to believe they are all making money in this market ...

cheers,

Hmm, results look like a digital version of the film Panoptic camera, or Larscan, as built by MIchael Dusariez.  I still have one built from an old Zeiss camera taking 120 roll film.  I liked those images.  I may have to look into the digital versions.

not sure I mentioned this before but some time ago I was asked about the prop blades effect and at the time I made s simulation of what was going on using a flat bed scanner as the equivalent of the rolling shutter ... which is a offshoot of focal plane shutters ... you can read all about it here:

PTassembler and related sites ... impressive!!

My recent forays into panoramic photography are based on using a camera intended for machine vision applications ... a monochrome linear array camera ... and placing it atop a motorized rotating tripod head. No article yet but photograph can be sees at:
