Generation

# ISO and Image Noise **ISO** controls your camera sensor's sensitivity to light—higher ISO values let you shoot in darker conditions without a flash, but there's a tradeoff. When you increase ISO, you're essentially amplifying the sensor's signal, which also amplifies the random electrical interference present in all digital sensors. This interference appears as **image noise**: those grainy, speckled artifacts you see in low-light photos, similar to the static on an old TV. The key is finding the lowest ISO that still gives you a proper exposure, balancing brightness against image quality.
