What Does Iso Stand For In Cameras

Not a lot of grain in this photo — probably taken at a low ISO, so. Merely what does ISO mean? Oh boy, are you in the right identify.

Why is the sensitivity of your camera called 'ISO'?

… And is the proper name related to the International Standards Organization? Spoiler alert: Yes, yes it is.

Photographers dearest talking about the 'exposure triangle' of Shutter Speed, Aperture, and ISO. But have you e'er stopped to think what ISO really stands for?

ISO is the culmination of three different systems for measuring camera sensitivity, including the The American Standards Association (ASA) and the Deutsches Institut für Normung (DIN) standards. Both of these were in use until every bit recently as the mid-1979, when the International Organization for Standardization (ISO) stuck an oar in and added their own initial set up of definitions.

Today's ISO values are defined past ISO 12232:2006 (that is, ISO standard number 12232, revised in 2006). This ISO standard "specifies the method for assigning and reporting ISO speed ratings, ISO speed latitude ratings, standard output sensitivity values, and recommended exposure index values, for digital still cameras. ISO 12232:2006 is applicative to both monochrome and color digital still cameras."

And so now you know. For the ultimate piece of photographic trivia, memorize "ISO 12232", and the side by side time your unworthy photography friends start harping on on most 'ISO', you tin can pull your smug face and get "Well, actually, did yous know…"

For extra geek cred, dig out your credit card and beat out the 92 Swiss Francs (USD 110 / GBP 67 / EUR 75) it costs to buy the full ISO standard and read the whole thing.

Oh geeky, delicious, photography nerd love-fest. How nosotros love thee.
