Lytro’s 755 megapixel Cinema light field camera

Lytro is taking its rich, volumetric 3D camera capture technology into the world of TV and film.
The company’s light field solution is a truly beautiful technology that may eventually be in every camera we snap a shot or video with. The tech essentially uses data on all of the available light in a photo to separate objects by depth and store them in a three-dimensional grid. In the future this technology will allow the simple creation of VR-ready navigable 3D spaces, but right now it’s enabling filmmakers the ability to achieve a level of detail and flexibility in gathering shots and making post-production edits that wasn’t previously possible.
Today, the company introduced Lytro Cinema, which is the company’s effort to woo those in the television and film industries with cool camera technology that makes their jobs easier.
The Lytro Cinema camera gathers a truly staggering amount of information on the world around it. The 755 RAW megapixel 40K resolution, 300 FPS camera takes in as much as400 gigabytes per second of data.
What that chunk of visual knowledge gives filmmakers is the freedom to make a number of creative decisions in post-production that would otherwise be impossible after they had pressed “record.”
Things like changing the depth of field, focus position, shutter speed or dynamic range can now take place after the fact thanks to the truly dynamic data being captured. Lytro believes that this tech is going to make the merger of CGI images and real-world footage even more seamless, and I believe it too.

Magnetic MoonWalker Shoes Ditch Gravity

A New York-based startup wants to send you there, replicating low-gravity environments with their smart, super-magnetic sneakers.The thick MoonWalker shoes from the startup Moonshine Crea promise to let wearers bounce around like Neil Armstrong. Each shoe contains N45 magnets — a fairly high grade of powerful rare-earth magnet — placed so their north poles face each other, creating a repellent force that “leaves you light on your feet and happy as an astronaut,” 

Hyperloop - The Fifth mode of Transportation

  • Goal:- 
  • Safer
  • Faster
  • Lower cost
  • More convenient
  • Immune to weather
  • Sustainably self-powering
  • Resistant to Earthquakes
  • Not disruptive to those along the route
What is this?

Existing conventional modes of transportation of people consists of four unique types: rail, road, water, and air. These modes of transport tend to be either relatively slow (e.g., road and water), expensive (e.g., air), or a combination of relatively slow and expensive (i.e., rail). Hyperloop is a new mode of transport that seeks to change this paradigm by being both fast and inexpensive for people and goods. Hyperloop is also unique in that it is an open design concept, similar to Linux. Feedback is desired from the community that can help advance the Hyperloop design and bring it from concept to reality. Hyperloop consists of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube. The capsules are supported on a cushion of air, featuring pressurized air and aerodynamic lift. The capsules are accelerated via a magnetic linear accelerator affixed at various stations on the low pressure tube with rotors contained in each capsule. Passengers may enter and exit Hyperloop at stations located either at the ends of the tube, or branches along the tube length.

Canon makes a 250-megapixel image sensor

The megapixel wars broke out on a new front today as Japanese camera giant Canon announced a head-spinning new sensor. The roughly 250-megapixel (19,580 x 12,600) APS-H CMOS sensor sets a world record for resolution in its size, according to a Canon release, and is said to be able to distinguish lettering on the side of an airplane from 18 km away. APS-H is a sensor size bigger than APS-C but smaller than full-frame, and is primarily used on Canon's legacy EOS-1D line of DSLRs.

The sensor has a fast signal readout speed of 1.25 billion pixels a second, and Canon says it has good noise performance despite the pixel count. Beside photos, the sensor can be used to capture incredibly high-resolution video  — about 30 times sharper than 4K — at five frames per second. Canon says the technology could be used in "specialized surveillance and crime prevention tools, ultra-high-resolution measuring instruments and other industrial equipment, and the field of visual expression."
Don't expect this to land in your next DSLR or five, then. But the announcement is a sign that sensor technology will continue to improve; Canon announced a 120-megapixel APS-H sensor back in 2010, when this year's 50-megapixel EOS 5DS would have been unthinkable.
