What issue occurs when the subject appears soft or smeared due to camera shake or motion?

• A. Blurred Subject
• B. Noise
• C. Color Correction
• D. Cropping

Answer: (A)

Sharpness depends on capturing a still moment; when movement happens during exposure, details smear. If the subject appears soft or smeared because the camera or the subject moved, that softness is blur. Blur comes from two common situations: camera shake, where the whole frame shifts as the shutter is open, and motion, where a moving subject carries its outline across the image during the exposure. This is different from noise, which is random grain added by high ISO, or color correction, which is adjusting colors after the fact, and from cropping, which changes composition rather than the actual sharpness. To reduce blur, use a faster shutter speed appropriate for the motion, stabilize the camera with a tripod or optical/IBIS stabilization, and improve lighting so you can keep the shutter short while still exposing well.
