DxOMark gives RED Helium 8K sensor a record-breaking 108 score

12 Jan

DxOMark has given RED’s 35.4MP Helium 8K sensor its highest overall score ever: 108. This makes the prototype sensor the second ever to exceed the 100 point milestone, joined only by the RED Epic Dragon prototype, which scored 101. DxOMark says the Helium is a ‘solid upgrade’ over the Epic Dragon, offering better color depth, less noise, improved low-light ISO and a greater dynamic range.

DxOMark explains that while both the Dragon and Helium sensors are ‘physically similar,’ the Helium ultimately offers more densely packed pixels at approximately 3.65 microns each. Less impressive is the organization’s assessment of the dynamic range, which measured at 15.2 stops versus RED’s advertised 16.5+ stops. That is still greater than the Epic Dragon’s DxOMark dynamic range rating of 14.8 stops, however. 

Because both the Helium 8K and Epic Dragon tests were performed with prototype devices, neither model will be officially added to DxOMark’s device ranking list. The company does present a ‘simulation’ ranking that shows where the two models would fall if they were included, however: above the Sony a7R II, Nikon D810, Sony Cyber-shot DSC-RX1R II, and the Pentax K-1.

8K Helium Super 35mm sensor on the way from RED

12 Jul

Movie camera manufacturer RED has announced that it will be introducing a new 8K sensor that it is calling Helium. At 29.9×15.77mm the new sensor is much smaller than the current 8K Dragon sensor, which measures 40.96×21.6mm, but both sensors have 8192×4320 pixels.

The attraction of the new Helium sensor is that a wider range of lenses will provide sufficient coverage for its shorter diagonal, even though it is slightly larger than the standard Super 35mm format. It should also be easier to make and may take some of the pressure off the company’s difficult delivery of the larger Dragon 8K VistaVision sized sensor. The Helium is designed to operate in the same Weapon camera, but the company’s CEO Jarred Land also let on that a new camera, the Epic-W, will also come with the new sensor.

The announcement was made in a casual way in Land’s July Update on the Red User forum and via pictures posted on Land’s Instagram and Facebook pages, as well as those of the company designer’s Matthew Tremblay. Little technical detail has been released so far, but it is known that the pixels will be just 3.65 microns and that the sensor will be available in ‘coming months’.

For more information see the RED website and REDuser forum.

Cloud Station: Floating Helium Roof for Ukraine Transport Hub

01 Mar

[ By Steph in Architecture & Public & Institutional. ]

Under the Cloud 1

A train station envisioned for the town of Sevastopol in Ukraine seems to be perpetually covered in clouds, topped with a light, helium-lifted structure inspired by airships. ‘Under the Cloud‘ consists of a passenger terminal building and a buoyant freeform canopy that hovers over the green roof of the main building.

The canopy shell has an aluminum frame with longitudinal and transverse trusses, the helium gas held inside a rigid framework in bags. With the guy lines securing it, it really does seem as if it could lift away into the sky at any moment.

Says designer Arthur Kupreychuk, “The supporting structure of the canopy is similar to the structure of an airship. The canopy strives upward by buoyancy forces, if its average density is less than the density of the atmosphere.”

What’s the purpose of this canopy? Judging by the designer’s other projects, it may just be for fun. Kupreychuk previously designed The Draft Parking Lot with the Car Service Station, another airship-inspired structure “conceived as the embodiment of the boundless creative thought of an architect, who often must try to restrict it and leave it unfulfilled.” This concept won the distinction of being “the most surreal project designed in ArchiCAD” in 2011.

Beautiful Suspended Bridge Hangs from Helium Balloons

31 Dec

[ By WebUrbanist in Architecture & Public & Institutional. ]

Neither this installation artist nor his work are full of hot air – this is no optical illusion or structural trick, but an actual bring hanging in mid-air that can actually hold the weight of a human user.

Oliver Grossetête  (images by Thierry Bal and Toby Savage) crafted this lovely slatwork structure from rope, wood and synthetic fabric, installed over water at a Japanese garden for the Tatton Park Biennial.

To call Grossetête obsessed with everyday uses for balloons would be an understatement. His other projects include a floating bench (strung up to helium-filled orbs) and a conceptual transportation system that (you guessed it) soars through the sky on the back of giant balloons.

In this case, three large, evenly-spaced balloons create a series of rises in the path below, while the rope-and-wood slats allow some flexibility as the construct rises, falls and sways in the wind.
