It seems to me to be too much of people “talking shop” rather than necessarily being funny. You could do the same thing with computer nerds, car geeks, audio/video geeks, etc. (I loved the segment of the girl taking a picture of a tree trunk though.)
Maybe they should focus more on the pretentious things photographers say, such as how artistic and high concept their own work is but everyone else’s work is garbage. You can find examples all over any given photography forum; someone will criticize the work of a Magnum photographer while providing a link to their own sad little Flickr account in some misguided attempt to show the world what “real” photography is. Subjectivity apparently doesn’t exist in their world.
