Thanks to everyone for the replies. I don't have a solution yet, but I'm going to keep working on it. I think the main issue has to do with the brightness of the Passport screen overwhelming the camera. It's not handling it well. I may end up needing to buy another web cam.


Thanks for the info. That's a very good point. In my case, though, I'm not concerned. I have every intention of doing a firmware reset and generating a new key from dice, so this seed -- even if it can be recovered from the image -- is throw-away. The wallet is empty.
