The maximum ISO range of the camera is typically determined by the manufacturer and can vary depending on the model. Generally, modern digital cameras have ISO ranges that extend up to ISO 12800 or higher. This high ISO capability allows for shooting in low light conditions without the need for a flash, but it may also result in increased noise and loss of image quality. It is important to understand the trade-offs between high ISO settings and image quality when selecting the appropriate ISO for a given shooting situation.
