Re: [gphoto-devel] Adding support for Nikon P7100

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Howdy,

First surprise was that capture worked.  When USB attached the lens
normally has stayed retracted and closed.  After the first command it
extended, then took a picture.  I guess I can run tethered, if I want.

The rest of the information follows. (Unfortunately wrapped) Out of
curiosity, what is the difference between Generic Image Capture and Open
Capture?  Vendor specific capture is rather obvious.

Am I going down the right path, filling in the fields as I did before,
this time adding TPT_CAP in the third field?  I notice that on many of
the Nikon cameras an additional bit was ORed in, with a name suggesting
that there was something slightly broken about the capture.

Presuming all is well, is this something you want me to do, and send you
a patch, or is it so trivial that I've already given you enough
information, and it's easier to do yourself?

Thanks,
Dale
