When choosing the right camera technology, understanding the key differences between global and rolling shutters is essential. A rolling shutter captures images by scanning the sensor line-by-line from top to bottom, which can lead to motion artifacts when photographing fast-moving objects. In contrast, a global shutter captures the entire frame at once, eliminating such distortions and providing clear images of dynamic scenes. The video above demonstrates these differences with a side-by-side comparison of a spinning fan. Notice how the global shutter (right) maintains the fan's shape, while the rolling shutter (left) shows visible distortions. This comparison highlights the global shutter's advantage in applications requiring precise, high-speed imaging, while rolling shutters remain a versatile and cost-effective choice for less dynamic scenes.
