Less light makes an image ____ in a digital camera?

• A. Warmer
• B. Brighter
• C. Sharper
• D. Darker

Answer: (D)

Less light reduces the exposure the sensor receives, so the image becomes darker. Brightness in digital photography is all about exposure, which depends on shutter speed, aperture, and ISO. If you cut the light without changing those settings, there’s less information recorded, and the result is a darker picture. Color warmth and sharpness aren’t direct results of the light level: color temperature (white balance) affects warmth, while sharpness depends on focus, lens quality, and motion or noise, not simply how much light is present. If you want a brighter image in low light, you’d typically raise exposure by widening the aperture, slowing the shutter, or increasing ISO, each with its own trade-offs.
