Provoke was a short lived photo magazine printed in Japan in 1968 - there were only three issues but it set off a spark in Japan.  The three volumes have been re-released - I got mine from this photo bookstore in Tokyo.  The predominant style is ‘are, Bure, bokeh’  which is grainy, blurry and out of focus. The masters of optics and camera manufacture in Japan at the time must have wondered why they were killing themselves to make high quality lenses if this was the type of photography that was gonna be displayed.  I don’t know but would wonder if this new style of photography led to the popularization of the cheap point and shoot cameras?
