(exposures) to be taken from the sensor at a minimum/maximum and however many in
between. However the camera does not stop moving during the process so I would
reasonably imagine it would have _some_ effect in the image, albeit small. Is this correct?
Panoscan has only an illustration of the effect on their own webiste to accompany the
explanation. It certainly would be best to see an actual raw image at full resolution to see
precisely what is going on, however Spheron did not make such examples available to me
when I was in the market for my camera. I keep checking the Spheron site even now for
such a thing but still have not seen it. :(
