Curious Wobbling Speaker Effect Captured with DSLR Camera
A speaker appears to wobble in slow motion in this short video by photographer drummaboy5189. He created the video by playing a 61 Hz tone on the speaker and then filming it at 60 frames per second with his DSLR. The effect is caused by the camera’s rolling shutter. We previously wrote about a similar shutter-related optical trick involving water.
