Please, Rob. Even I don't click on your links anymore (without a reasonable explanation). One too many times being burnt by some hideous swamp rock music.
Yes, the title is obviously* about The Blow Up movie... so what? What is the connection between the movie and the links you provided?
* even that is actually far from obvious for anyone but us old farts.
Slobodan, as you are averse to taking me on trust, I am obliged to ask you if you actually watched?
If you did, you will have understood that the concept of the documentary was to investigate the reality of the photographers of that period with the rather unfocussed image of the people that Antonioni managed to create, which whilst it encouraged many a callow youth to buy a camera, ignored the reality that having silly girls trample your rolls of Colorama was just not going to happen willingly; it was bother enough taping the soles of their shoes to stop them putting black scuff lines everywhere which, pre-PS, was not a fun thing to have to adjust in the darkroom.
To conclude, it was a documentary about photography, London and the swinging sixties and those who made it happen.
Did that help?
