ISO Settings

ISO settings in photography control the camera's sensitivity to light. Lower ISO numbers (like 100 or 200) mean less sensitivity, suitable for bright conditions, resulting in clearer images with less noise. Higher ISO numbers (such as 800 or 1600) increase sensitivity, helping you capture brighter images in low light but may introduce graininess or noise. Adjusting ISO allows you to balance exposure when shutter speed or aperture can’t be changed enough, ensuring your photos are well-lit without blurring or loss of detail.
