Which statement describes the impact of increasing the number of bits per pixel?

• A. More shades of gray
• B. Higher resolution
• C. Increased color accuracy
• D. Faster processing

Answer: (A)

Raising the number of bits per pixel increases color depth, meaning each pixel can represent more tonal steps. In a grayscale image, this directly means more shades of gray are available, giving smoother transitions between light and dark areas. It doesn’t change how many pixels the image has, so it won’t increase spatial resolution. It also doesn’t automatically improve color accuracy, which depends on calibration and color management, not just bit depth. And higher bit depth doesn’t inherently make processing faster; more data can even require more processing power. So the effect described by increasing bits per pixel is the availability of more shades of gray.
