In digital cameras, digital noise is similar to which traditional film effect?

• A. Blur
• B. Film grain
• C. Chromatic aberration
• D. Pixelation

Answer: (B)

Digital noise is the random speckling of brightness and color that shows up in photographs, especially when you push the ISO or shoot in low light. That gritty, grainy texture is very similar to film grain—the tiny particles in traditional photographic film that give images a textured, speckled look. Both create a grainy feel across the image rather than a uniform change in color or sharpness.

Why this fits best: film grain is a direct analogue for the random, textured appearance you get with digital noise, so it’s the closest match among the choices. The other effects describe different problems: blur softens fine detail, chromatic aberration adds color fringes around high-contrast edges, and pixelation shows up as blocky squares when an image is enlarged or has limited resolution.
