Phantom, the company behind some insanehigh-speed cameras has announced their new flagship camera, the Phantom v2511. Bumping up the specs across the board from their current flagship device, this beast manages to pack in up to 25,600 frames per second at 1280 x 800 resolution (just over 720p).
Who says you can’t learn from video games? Shown off in the above video is a preview of an upcoming first-person simulation game that takes the concept of the first person shooter in a much more photographic direction. Read more…
Take a look at that stock camera app on your iPhone. Does a fair job, doesn’t it? Then SnappyCam Pro 3.0 lands on it and makes you realize how truly slow the stock app takes photos. For your reference, it’s about 3-to-6 images per second at full resolution (assuming you’re using an iPhone 5).
SnappyCam, on the other hand, is able to take 20 full-resolution images per second on the iPhone 5. You read that right, a whopping 20 frames per second. It’s all thanks to John Papandriopoulos (who has a Ph.D. in electrical engineering) and his frustration with what he thought to be “inadequate” camera applications (we’re looking at you, stock camera app).

It seems like developers are always finding goodies hidden in Apple’s iOS 7 beta software. Late last month it was discovered that iOS 7 may eventually be capable of detecting blinking and smiling in photos, and now? Well, let’s just say Apple may be developing a slow-motion camera for the next iteration of the iPhone, which is expected to be announced later this year. Read more…
Canon’s DSLRs come with a variety of continuous shooting speeds, ranging from 2.5 frames per second on the 300D (AKA Digital Rebel/Kiss Digital) to a whopping 14 frames per second on the high-end 1D-X. If you want to get a taste of what these shutter speeds sound like on the actual cameras, check out the comparison video above by YouTube user dochero2005. Read more…
They didn’t up the FPS that high, though (the resulting videos would take an eternity to watch). Instead, they chose to record at a much-more-reasonable 18,000fps (at 720p), and used a macro lens in order to capture the beautiful details of the bubbles as they disintegrate. This is the slowest footage the Slow Mo Guys have ever captured, and the results are quite beautiful.
If you think 14fps on a high end DSLR is fast, check out this video by Mike’s Electric Stuff. In it, he does an extreme teardown of a cheap Panasonic Lumix compact camera and spends 30 minutes exploring and explaining the various components. At about 18 minutes in, he hooks up a signal generator to the shutter mechanism to see how fast the shutter can flap. He’s able to take it up to around 70 flaps per second before the shutter begins to stutter. The limiting factor in FPS isn’t the mechanical components of a camera, but how fast the sensor and memory card can capture and store data.
When recording video, a camera’s frame rate can produce some pretty strange effects. If matched up with a helicopter’s blades, a helicopter looks like it’s hovering in midair with motionless blades. YouTube user mrbibio found that the same thing can be done with falling water. His technique is brilliant: by pressing a water tube against a speaker, mrbibio was able to control the vibration frequency of the water flowing through the tube. He then adjusted the pulses of the water to match up with the frame rate of his Canon 5D Mark II. The result is a video of the water looking as though it’s frozen in time.
German scientists have been awarded a Guinness World Record for “fastest movie” after successfully capturing two images of an X-ray laser beam 50 femtoseconds apart. One femtosecond is equal to one quadrillionth (or one millionth of one billionth) of a second. Here’s some science talk explaining it:
[...] the scientists split the X-ray laser beam into two flashes and sent one of them via a detour of only 0.015 millimetres, making it arrive 50 femtoseconds later than the first one. Since no detector can be read out so fast, the scientists stored both images as superimposed holograms, allowing the subsequent reconstruction of the single images.
With these experiments, the scientists showed that this record slow motion is achievable. However, they did not only take the world’s fastest but probably also the shortest film – with just two images. Thus, additional development work is necessary for the use of this method in practice. [#]
Here’s an interesting look at the amazing camera being developed at MIT that shoots a staggering one trillion frames per second — fast enough to create footage of light traveling:
[...] the researchers were able to create slow-motion movies, showing what appears to be a bullet of light that moves from one end of the bottle to the other [...] Each horizontal line is exposed for just 1.71 picoseconds, or trillionths of a second, Dr. Raskar said — enough time for the laser beam to travel less than half a millimeter through the fluid inside the bottle.
To create a movie of the event, the researchers record about 500 frames in just under a nanosecond, or a billionth of a second. Because each individual movie has a very narrow field of view, they repeat the process a number of times, scanning it vertically to build a complete scene that shows the beam moving from one end of the bottle, bouncing off the cap and then scattering back through the fluid. If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years. [#]
They believe that the technology may one day be useful for medicine, industry, science, or even consumer photography.
