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.
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.
Here’s a video comparing the mirror and shutter curtain mechanisms of the Canon 5D Mark II, Canon 7D, Nikon D700, and Nikon D7000 DSLRs. It’s pretty surprising how much the Canon mirrors bounce compared to the Nikon ones…

Devin Graham shot this beautiful surfing footage using a Canon 7D and a couple lenses (70-200mm and 100-400mm) with a 2x teleconverter, so much of the footage was shot at 800mm. The slow motion is actually “faked” (here’s another faked 7D video) using software:
To get the “super slow motion”, after I filmed at 60fps, I through it into the program “After Effects”. I used an effect that comes with the program called “Time Warp”. This allowed me to make the 60fps, to 1000fps. The way this works is the computer processes/adds frames in between the frames that are already in existence. It took several days for the computer to process the clips into the super slow motion that appears as well, so it does take a lot out of the computer, as far as processing goes.
