Wedding photographer Lee Morris recently had the idea of trying his hand at making a wedding video with his still photography mindset. His idea was to slow down the video to make it more of a “moving image”, bringing it more into his realm of expertise. To do this, he photographed a wedding at 60fps using a Canon 60D and then slowed the video down to 24fps afterward.

Here’s a slow motion video showing a closeup look at the human eye, our amazing biological lens (and sensor). You might be surprised at how mechanical its movements are and how fluid the iris is. Another crazy fact is that we’re continually relying on “image stabilization” to see things clearly:
The visual system in the brain is too slow to process information if the images are slipping across the retina at more than a few degrees per second. Thus, for humans to be able to see while moving, the brain must compensate for the motion of the head by turning the eyes. [#]
To see a quick demonstration of this fact, try the following experiment: hold your hand up, about one foot in front of your nose. Keep your head still, and shake your hand from side to side, slowly at first, and then faster and faster. At first you will be able to see your fingers quite clearly. But as the frequency of shaking passes about 1 Hz, the fingers will become a blur. Now, keep your hand still, and shake your head. No matter how fast you shake your head, the image of your fingers remains clear. This demonstrates that the brain can move the eyes opposite to head motion much better than it can follow, or pursue, a hand movement. When your pursuit system fails to keep up with the moving hand, images slip on the retina and you see a blurred hand. [#]
Like with cameras, our built-in image stabilization can deal with head shake but not motion blur.
Melbourne-based design studio Betty Wants In is at it again. They’ve created this stunning slow-mo video of BASE jumpers doing their thing — a perfect followup to the skydiving one they shared back in April. The footage was captured with GoPro cameras and then slowed down using Twixtor, just like the crazy wingsuit video we shared yesterday.
Earlier this year, daredevil BASE jumper Jeb Corliss leaped off a cliff in Switzerland in a wingsuit and wearing 5 separate GoPro cameras. One of the things Corliss did afterward was create this ethereal slow-motion video with the footage using Twixtor, the artificial slowmo program that has become quite popular as of late.
While we’re on the topic of high-speed cameras (and slow motion videos), here’s a beautiful slow-motion video of an eagle owl “attacking” a camera, shot at 1,000fps with a Photron FASTCAM SA2. The new Phantom v1610 camera announced today can record footage 1000 times slower than this.
Shooting 4.5 million frames per second of molecules using an x-ray flash is impressive, but can non-scientific cameras come anywhere close? The answer is yes: Vision Research has a new Phantom high speed camera called the v1610 that can capture footage at a whopping 1,000,000fps. Granted, the resolution needs to be a paltry 128×16 for that fps, but at a full 1280×800 it still shoots at 16,000fps. To give you an idea of what 1 million fps is like, consider this: 1 second of the footage will provide you with 9.25 hours of uber-slow motion 30fps video.
Vibration tester manufacturer Fluke recently published this video showing what the world of vibration looks like at 1,000 frames per second.
So much of movement is invisible to the human eye. Sure, our eyes can see a cymbal move when struck by a drum stick. But it’s what our eyes can’t see that is most captivating. Metal rippling as if it were fabric fluttering in the wind, droplets of water bouncing and hovering just above the surface of a puddle; the beauty and science of movement is in the details. And the details are often the result of vibrations. [#]
Everything was shot using a Phantom HD Gold high speed camera.

When Eadweard Muybridge shot the first motion picture of a galloping horse back in 1878, he used 24 individual cameras placed 27 inches apart, using trip wires to fire off each camera one thousandth of a second after the previous one. With fancy high-speed camera rentals priced at thousands of dollars a day, YouTube member Destin came up with a Muybridge-esque technique for capturing a bullet flying through the air using an ordinary DSLR: he shoots a bullet for each frame and uses a fancy trigger to capture the bullet at increasing distances, combining the resulting images into a neat super slow motion video.
