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.

What visual effect might a rolling shutter create in a video?

• A horizontal line

• A vertical band or pillar of light

• A diagonal stripe

• A circular halo

How does a rolling shutter capture an image?

• By scanning the image line by line

• By using a flash to illuminate the scene

• By taking multiple exposures

• By capturing the entire frame at once

What happens to the rolling shutter scan direction when the camera is turned vertically?

• It remains the same

• It becomes diagonal

• It changes from top to bottom to side to side

• It changes from side to side to top to bottom

Why do bright bands appear in images of lightning captured with a rolling shutter?

• Because of the rolling shutter's scanning process

• Due to the camera's inability to handle bright light

• Due to a malfunction in the camera sensor

• Because the camera lens is dirty

How does the orientation of the camera affect the capture of lightning with a rolling shutter?

• It doesn't affect the capture

• It changes the color of the lightning

• It alters the brightness of the entire frame

• It affects which part of the frame is bright
