Lightning vs Rolling Shutter

The video explains the phenomenon of rolling shutter in cameras, which can create visual artifacts like vertical bands in images, especially when capturing fast events like lightning. It describes how the rolling shutter works by scanning images quickly, similar to scanning a piece of paper. The video also compares how lightning is captured differently in portrait and landscape modes due to the rolling shutter's scanning direction, resulting in varying brightness across the image.
