Even Museums can make mistakes

I once went to a museum in Florida that had an exhibit on the history of photography. There was one case that displayed what they called a group of daguerreotypes, but there were clearly ambrotypes mixed in. They are actually pretty easy to differentiate: dags will reflect like mirrors if you shift your angle, and that won't happen with ambros. I wanted to point out the mistake but I figured they wouldn't really care.
