Originally posted by aurele the ISO value for film dates back to 1942 (revised later in 1943 to 1947) at that time the organisation was still called ANSI (later in 1947 became the ISO - because it was international and not only american).
Before, it was express in national value - DIN in germany, ASA in France, BSI for the british, GOST for the Russia.
So the guy is basically right, the name "ISO" is not really related to the ISO organisation name. And by the way the real name is not "ISO" only but "exposure value ISO" because internationaly equalized (equivalent - hence ""ISO" from greek"deduction, i guess) to be able to convert DIN / BSI / ASA / GOST exposure value to unique ISO exposure value.
Go to this webpage .iso.org/iso/home.html , And tell that to them. that their official Logo doesn't mean anything. This organization produces standards for more than just film. Anything that needs a standard is certified by this organization. Weights, measurements, screw threads.
And by the way, I know the history of the organization and the standards that were implemented for photography, Along with many other standards that were implemented by this organization.
The ISO organization establishes standards for many other industrial and nonindustrial products. I have been dealing with these standards for over 40 years. And it does mean something. It means when you go into a hardware store, to buy a bolt it will fit your application. Everything from wire to plumbing fittings, even the oil in your car has an ISO standard. Without these standards it would be impossible to do business with other countries. Before standards were established, in this country every Company had their own standards for screw threads. You could not go into a hardware store and buy a bolt, and be assured that it would fit your application. It had to be custom-made. Something we take for granted now.
Thousands of years ago every country had their own unit of measurement. One kingdom imported Masons and other skilled labor From other countries and quickly found out that each was using their own unit of measurement. They quickly realized that they had to establish a uniform standard to get anything done. They created a Rosetta Stone of standards, So to speak. The first known standards that ever existed.
They needed them then, and we need them now. ISO is definitely not just a word. It is a set of standards that most of the world follow.
