ISO
ISO is a camera setting that controls a sensor’s sensitivity to light and plays a major role in exposure and image noise.

ISO determines how strongly a camera sensor amplifies incoming light signals. Lower ISO values such as 100 or 200 produce cleaner images with minimal noise but require more light. Higher ISO values such as 1600 or 3200 increase brightness in low-light environments but also introduce grain and digital noise. Modern cinema cameras often feature dual native ISO systems that optimize performance at two sensitivity levels, allowing filmmakers to shoot clean images in darker conditions. ISO is one component of the exposure triangle, working alongside aperture and shutter speed to achieve proper brightness. Choosing the correct ISO requires balancing lighting conditions, desired image quality, and artistic intent. Excessive ISO can degrade detail and color accuracy, while too little ISO can result in underexposed footage.
