Dynachrome 35mm slide film ad in LIFE<\/p><\/div>\n

Toronto<\/strong>. In the March 27th, 1964<\/a> issue of LIFE magazine (p42), the 3M company ran this unusual ad for a colour transparency film called Dynachrome. Did you ever use it?<\/p>\n

In 1954, the American government was hell-bent to separate any perceived trusts by large companies . In that year, Kodak was forced to separate Kodachrome manufacture and processing.<\/p>\n

When Kodachrome patents expired, some organizations made a Kodachrome clone with built-in processing, selling for the price of Kodak’s film alone (companies too small for the trust busters). Around 1959 a clone was made by Dynacolor and called Dynachrome. Around 1963, the company was sold to 3M and the above advertisement showed up and ran for a few months in LIFE magazine. 3M used price to whittle off a bit of the burgeoning amateur photography market for itself.<\/p>\n

You can read more detail about the history of the film and the suspected production and processing variations underneath the marketing names on the Photography Forums web site<\/a>.<\/p>\n
