Silly question...

What in the world does ISO stand for? After 2 months of having this DSLR of mine, I still don't know what it stands for. All I can find on the web is "International Standards Organization".

What does an international organization have to do with the standards of how we set our ISO settings?:dunno :rofl Seems to me it would make more sense if it stood for "Image Sensor Optimizer". However, I do notice the higher the ISO, the fuzzier the picture becomes.

Sorry for not knowing DSLR or even FSLR stuff, but I've been busy, and I can't find just anything in the manual nor on the web.:rolleyes If it does stand for international standards organization, then why such a name?

Thanks!

ISO is interenational Standards Organization I believe. ASA is American Standards Association and they both are used in reference with Film Speed or the sensitivity to light, which is probably more accurate.

That is correct. It's just a large organization that maintains various standards & this happens to be one of them. They are kind of like an international UL, or ASTM, or CSA, etc, etc. The actual official name is in French, but ends up abbreviating to ISO & translating to International Standards Organization.
