Question:

Why does a moving person appear smudged and leave an afterimage when taking photos at night using the Samsung Galaxy S20 FE?

Answer:

In night mode, the camera captures multiple images and combines them to create a brighter, clearer photo in low light conditions. This can result in an unnatural appearance for moving subjects, leaving behind an afterimage. To avoid this issue, it's best to use night mode in a stable environment without moving objects.

Terms:

Night mode - A camera feature that helps capture better quality photos in low light conditions by combining multiple images.

Composite screen - The final image displayed after merging multiple images captured by the camera.

Afterimage - An impression left on the screen after a moving object has passed through the frame.
