There was a time when high speed was ASA 400 and when GAF came out with Anscochrome 500 it was a revolution. At that time, the late sixties through the seventies, ASA 500 in color slide film was unheard of. Speed usually was obtained by push processing Ektachrome. I always carried a few rolls of this film in my bag. Things are so easy now when one cal dial up speed by changing the ISO on digital cameras. Yes ASA became ISO. Today one can also set white balance at any time. In the old days one had to finish the roll in order to change speed or white balance by using different films. These shots from the seventies where made at the good old Brooklyn Botanic garden. I especially love the grain that gives the images a dreamy feeling.
