Besides being patient, what can I do with a somewhat
unsupported digital camera?  I say "somewhat" because
Digikam and Gwenview do display thumbnails correctly. 
However, the downloaded jpg's are somewhat scrambled
-- the image breaks into wide horizontal tinted
shifted bands.

I'm wondering whether I can eliminate this banding by
changing the gphoto download speed or some other
gphoto option -- --speed, --frames, --interval

gphoto --auto-detect gives


Model                          Port
Mass Storage Camera            disk:/media/disk




The driver, spca533, is used in a large number of
cameras.  See:

A number of cameras use spca50x.  I tried setting
digikam to some of these cameras, hoping that spca50x
might be close enough to spca533 to allow digikam to
connect, but it didn't work.
