Blow-up is one of those films that film historians love. I really like it, but it may be too pretentious for some. The director Michelangelo Antonioni is one of the big italian directors from what many would consider italy's golden age of cinema (the 50's to 60's)
It is a great story line for photog nerds: a fashion photographer whom thinks he may have accidentally taken a photo of a murder. 'Blow-up' refers of course to what he does in the darkroom, to the general chaos that ensues, and I think to what Antonioni wanted to do with your head (the ending is a little crazy). It has been a long time since I saw this in some film studies course, so I can't remember the details. I guess i will add it to my 'to watch/rewatch' list, which has some new additions from this thread
And yes, its a good old
Nikon FEdit: Somewhere a couple of audio nerds are having a parallel discussion about movies where audio equipment plays a pivotal role, and one of these audio nerds will mention
Blow Out -- which is an homage/rip off by brian depalma about an audio engineer that accidentally records a murder. This, too me, gives Blow-up bonus nerd points
