What is the impact of low ISO settings on image quality?

Low ISO settings have a significant impact on image quality, primarily by reducing noise and improving the overall quality of the image. When you set your camera to a low ISO, typically ranging from 100 to 200, the sensor is less sensitive to light. This results in a cleaner image with finer detail and less grain.

One of the main advantages of using a low ISO is the reduction of digital noise, which often becomes more pronounced at higher ISO settings, particularly in low-light situations. Noise can disrupt the smoothness of an image and affect the visibility of fine details, so minimizing it is crucial for producing high-quality photographs.

Additionally, low ISO settings help maintain accurate color reproduction and enhance dynamic range, leading to richer and more distinct color variations in the image. This combination of reduced noise and improved color fidelity contributes directly to the perceived quality of the final photograph, allowing for better sharpness, contrast, and detail in both well-lit and shaded areas of the scene.
