re: #262 Cineaste

Though I would submit, Walter, that often the person in question is working in their field of expertise. A photographer presenting photographic evidence of climate change is a good source. A photographer analyzing computer models is a less good source.

How so?

Playing devils advocate here, but was that photographer at that very same place 10/20/50 years ago? Perhaps the same exact thing happens there every 50 years. A scientist would come up with ways to find out. A cinematographer, not so much

THAT a cinematographer found it to happen at the very time he was there to film it proves only that it happened at the time he was there to film it

AGAIN ,,, devils advocate
