Destin from SmarterEveryDay has posted an incredible video explaining how a lawn mower cuts grass. It is way more interesting and memorable than you might think. The killer feature of mowers turns out to be the air flow generated by the machine which makes it possible to cut the grass even. The clip goes into detail on how it works and in an excellent series of clips, shows how it looks like at 50,000fps using a Phantom Camera. Highly Recommended to watch and subscribe to SmarterEveryDay for more great content! -HSC
The National Geographic Channel in conjunction with Clark lab at US Riverside, Dudley lab at UC Berkeley, have posted a video that shows the process of capturing hummingbirds in flight, feeding, and doing acrobatics all in glorious 4k at 2000fps. It is probably the most scientifically worthy portrayal of hummingbirds in flight ever to be documented.
The intricacies of flight, hovering and coping with the environmental elements that hummingbirds have to fend off and how they accomplish it are now being deciphered with the help of 4k Phantom Flex cameras in great detail mainly shot by naturalist filmmaker Anand Varma. This is all part of a recent National Geographic story on hummingbirds here!
Sometimes all it takes to embark on a new project is some unexpected inspiration. On the Incredible Slow Motion video by Veritasium – Seeing the Invisible: Schlieren Imaging in SLOW MOTION we are not only inspired but awestruck by the results of this simple and doable at home scientific experiment. The experiment allows a camera to visualize the vortexes of gases and temperature differences in the air which serve to create some very interesting scientific experiments and or artistic visualizations.
You will need a Concave Parabolic Mirror like the ones used in reflective Newtonian telescopes, “you may have one lying around from your stargazing days”, you will also need a small light source like an LED flashlight or single diode and finally a razor blade or similar precise object to cut off the light to the camera on a plane.
We have to share some amazingly cool slow motion videos we came across recently. There is continuous production of quality high speed content as the democratization of slow motion cameras is happening. However there is so much content being produced that is sometimes easy to miss.
The videos below are using Phantom cameras or experimental cameras in the mid 20th century capable of 15 million frames/sec to capture the initial fireball of a nuclear detonation. That rapatronic camera used an array of separate camera modules to reach that speed. However the frames recorded only were fractions of a second
The Phantom Flex 4k camera has made a big splash in TV, Film and Youtube with it’s amazing 4k resolution at 1000fps with a large S35mm sensor. However the first iteration of the camera only had a very fast reading; but in the end a rolling shutter sensor. This made the camera an option for visual recording only; leaving scientific research at 4k out of the realm of the camera due to distortion.
That changes today with the Phantom Flex4k-GS which offers the option to use the sensor in both rolling shutter and Global Shutter mode which is a first on a camera of this resolution. Now scientists can use the resolution prowess of the camera to examine minute detail that needs extreme speeds to be recorded.
Over the last four weeks testing and shooting with the edgertronic high speed camera we have a complete sense of the capabilities, strength and weaknesses that make up this kit. The portability of the setup with wireless router connectivity makes it a joy to go out and shoot nature and locations out of the studio.
Part 3 of this review will focus on the camera’s portable setup capability. We will also go into a recent features introduced since the edgertronic SC1 was reviewed last year and things still left to add into the platform plus, a conclusion for the entire review.
