I didn’t realize that before the land survey photographs of 1861-1912, illustrators were commissioned to sketch the newly acquired territory. The use of drawings (reproduced as multicolored lithographs) began in 1850. This little bit of rhetorical evidence is conveniently left out when discussing the supposedly profound impact of photography on conservation. Perhaps it would be better cast as the impact of illustration on conservation.
Just a momentary brainwave . . .
On a completely unrelated note, I notice that the IMDB entry for Bad Santa lists that it has an R rating for pervasive language. Bad proofreading!
