What causes light streaks in pictures and how can they be prevented or minimized?

Light streaks in pictures are caused by overexposure to light, often due to a long exposure time or a bright light source. To prevent or minimize light streaks, you can adjust the exposure settings on your camera, use a lens hood to block excess light, or avoid shooting directly into bright light sources. Additionally, using a tripod can help stabilize the camera and reduce the chances of capturing unwanted light streaks.
