Ready? Awesome, let’s do it…
The ISO Myth
Ask anyone that has been in photography for a while, and you’ll find that most will tell you that ISO is an acronym for; International Standards Organization.
And that you should pronounce it “eye – ess – oh.”
There is no such thing as an International Standards Organization!
Don’t believe me? Google it.
Nothing. Notta. Zilch. It doesn’t exist.
Here’s the search result…
As you can see in the image above, the listing for that search lists a company called: “International Organization for Standardization.”
Which is not the same as “International Standards Organization.”
Am I splitting hairs? Maybe.
But, before you get mad at me, please take 3 minutes to read the rest of the article for additional facts that the two are not one and the same.
So, What Does ISO Mean & What Does It Stand for?
So why all the confusion?
Well, there is such a thing as the “International Organization of Standardization” (or IOS).
The International Organization of Standardization is a non-profit organization based in Geneva, Switzerland.
Their mission is to bring together experts to share knowledge. Intending to develop voluntary, consensus-based, market-relevant International Standards that support innovation and provide solutions to global challenges… yes, that was a mouthful!
One of them being film. However, the acronym for their business should be IOS and not ISO.
To make things more confusing, they adopted “ISO” vs. IOS. Here is a quote from the International Organization for Standardization website…
The Truth About ISO
In short, ISO is not an acronym for “International Standardization Organization”. It’s a word that was derived from another (Greek) word isos.
This means you don’t spell out “I.S.O.” when referring to it. Instead (since it’s a word), it’s pronounced: “eye-so.”
Think of it like this; it’s like a logo for the International Organization for Standardization. Just like you wouldn’t spell out the word A.P.P.L.E. you would just say the word.
Now, here is the real question…
Does It Really Matter?
In the grander scheme of things… no. It’s not going to make you a better photographer.
So, what’s going to make you a better photographer? Well, knowing how to use ISO for your creative vision. That’s a story for another day, though.

Guilty As Charged
Truth be told, I’ve been saying “I.S.O.” for 25 years! I had no idea until another photographer corrected me.
But, my photography skills didn’t change one way or the other.
