Which ISO would produce the sharpest detail and least digital noise?

Explanation:
Lower ISO controls how much the sensor signal is amplified. When you use a lower setting, the camera amplifies less, so you get less digital noise and finer tonal detail, which helps edges and textures read as crisper. As you raise ISO, the sensor signal is amplified more, which boosts noise across shadows and midtones and can smear fine detail, making the image look less sharp even if it’s brighter. So, among the options, the lowest ISO produces the cleanest image with the most apparent sharpness, provided exposure is adequate. If lighting requires more light quickly, you might raise ISO, but there’s a trade-off with more noise and less perceived sharpness.
