whats din ?

I always wondered about that too. WHAT KIND OF FUCKING IDIOT MADE THAT CALL?

>>1506543
Deutsche Industrie Norm

With an extremely high probability that Mr. Google would have had this very information on his little homepage.

ISO is NOT International Standards Organization.
It just means "equal" in greek.


>>1506543
DIN = Deutsche Industrie Norm, German Industrial Standardization

>>1506550
>ISO is NOT International Standards Organization.

I'm glad you know a few Greek words, but ISO does indeed stand for International Standards Organization in this case.

>>1506541
Exactly. Why did OP post this?

this thread....it hurts....

>>1506553

It's called International Organization for Standardization, so the acronym should be IOS.

also: http://www.iso.org/iso/about/discover-iso_isos-name.htm

but still. what does op want to say?

Why is an essential technical element of photography named after an organization and not named based on the science/logic of the setting.

It's sort of like calling the aperture ICH (international committee of holes).
"My lens has an ICH of 1.4"

Because film sensitivity is a somewhat arbitrary measurement, therefore they developed a standard against to which measure. Therefore we have a number which denotes film sensitivity and the number is called by the acronym of the particular standards organization that came up with it.

As in, this films sensitivity is 400 according to the scale set by the ISO

>>1506580
ISO defines a lot of standards, ever heard of ISO9001? They have an infinite number of standards.
Before the film speed was rated on ISO, you had ASA and DIN, and many other before these. What ISO does is that it defines something(in this case the film speed) so that many different countries use the same standard instead of having 3 or 4 definitions for the same thing.

>It's sort of like calling the aperture ICH (international committee of holes).
>"My lens has an ICH of 1.4"
Is not. Aperture is aperture. In your example, it would be "My lens has an aperture of ICH 1.4"

>>1506553
According to wikipedia you both are kinda right.
>The organization says that ISO is not an acronym or initialism for the organization's full name in either official language; rather, recognizing that its initials would be different in different languages, it adopted ISO, based on the Greek word isos (ἴσος, meaning equal), as the universal short form of its name.

When I started out learning about how to use a camera I was calling ISO 'sensitivity', because it made it easier for me to remember. Even to this day I think to myself things like "getting dark, better go to 400 sensitivity."

Call that shit ASA or DIN or if you are a Russki call it GOST. Shit rocks.
