| Description: Specifies the ISO level set for the camera. ISO Sensitivity is a standard set by the International Organization for Standardization (ISO) that represents sensitivity to light as a numerical value as it pertains to either film or a digital sensor. A lower ISO value means less sensitivity to light, while a higher ISO means more sensitivity. The most common ISO values are 100, 200, 400, 800, 1600, and 3000. The lowest ISO setting or base ISO is typically 100, although some cameras go as low as 50 or even 25. Some older cameras will start at ISO 200. This should generally conform to ISO 12232:2019 |
