ISO is short for International Organization of Standardization, a governing body in Europe that provide standards in many aspect and subjects. Companies are using these ISO as proof of their quality and projecting their business image.
In the area of photography ISO means something else. It means film speed ratings and in digital photography it measures the sensitivity of the image sensor. ISO has replaced the ASA or American Standards Association. Those days films were sold as ASA50, ASA 100, ASA 200, ASA 400, ASA 800 and ASA1600. Digital cameras now have interchangeable ISO settings.
