It can introduce noise and grain.
Explicación
ISO in photography refers to the sensitivity of the camera's sensor to light. A higher ISO setting allows the camera to capture images in lower light conditions, but it also introduces more noise and grain into the image. Noise is a random variation of brightness or color information in images and is considered a form of electronic noise. Grain refers to the visible clumping of silver halide crystals in traditional film photography. Both noise and grain can degrade the quality of the image, making it less sharp and clear. Therefore, while a high ISO is useful in certain situations, it is not without its downsides.
