What will a camera show as it falls into a black hole?
<p>As a result, an exciting effect will occur: if the camera transmits typically, say, 25 frames per second, then as it approaches the black hole, we will receive fewer and fewer frames per second from the camera.</p>
<p>In other words, the camera signal will experience gravitational redshift: the wavelength of the signal from the camera will increase, and the closer the camera is to the black hole, the faster the shift will occur.</p>
<p>If there was an observer on the spacecraft with the camera, from their point of view, the camera would continue to shoot 25 frames per second. Still, due to gravitational time dilation, one second would appear longer. But in the frame of reference of an observer far from the black hole, time would pass much faster.</p>
