Video: A BTS look at what went into Hasselblad’s X System’s ergonomics, materials and user interface

26 May

Hasselblad is back with another video in its ongoing behind-the-scenes series, ‘Hasselblad’s Home.’ In the inaugural video, titled ‘The Design Philosophy Behind Creating the X System,’ Hasselblad shared an inside look at what went into developing the company’s mirrorless medium format camera. Now, in episode two, Hasselblad shares what’s gone into developing the ergonomics, materials and user interface of the Hasselblad X System.

Hasselblad’s factory in Gothenburg, Sweden.

The five-minute video, titled ‘The X System’s Ergonomics, Materials and Hasselblad User Interface’ shares an inside perspective of the decision-making process that went into making some of the most important components of Hasselblad’s X System. In Hasselblad’s own words:

‘This episode takes a deeper look into what went into creating the X System’s deep grip and the different materials tested for it before choosing the final one, the materials used for the camera itself, button choice and placement, as well as the thoughts behind building the Hasselblad User Interface (HUI).’

Regardless of whether or not you’ve ever used a Hasselblad camera, it’s a fascinating video that explains the rationale for the design decisions that are typically confined to within the walls of Hasselblad’s Gothenburg, Sweden operation.

The OnePlus 8 Pro has a new camera capable of seeing through some materials and objects

15 May

Announced in April, the new OnePlus 8 Pro smartphone is equipped with a multitude of high-end features, including interesting camera specs. But it also includes a unique 5MP Color Filter (infrared) camera. In the camera’s operating system, the mode that uses this particular camera array is referred to as the Photochrom filter within the native camera app, and as numerous users have been discovering this week, the Color Filter camera allows you to see through some objects, including various plastics.

Twitter user Ben Geskin photographed Oculus Quest controllers, for example, realizing that the Photochrome filter allows you to actually see through the dark gray plastic on the device. Other users have photographed television remotes, Apple TV devices and more, resulting in images showing internal circuitry that you cannot see with the naked eye or traditional image sensors.

OnePlus marketing materials divulge very little information about the Color Filter camera. On the OnePlus 8 Pro product listing, there is only a single example image, shown here in an enlarged format. Image credit: OnePlus

In marketing materials for the OnePlus 8 Pro, OnePlus states that the Photochrome filter allows the user to ‘turn ordinary scenes into surreal landscapes,’ but as OnePlus 8 Pro owners are finding out, it does a lot more than that. The 5MP Color Filter camera is essentially an IR camera, so if an object does not include a material which shields IR, the camera can see through it. In the video below from Unbox Therapy, you can view the effect on a pair of television remotes, Apple TV and a Nintendo Switch Pro controller. You can also see in the video below that the Color Filter camera can partially see through some fabrics.

There is a lot more to the OnePlus 8 Pro camera for photographers than the interesting Color Filter camera. The OnePlus 8 Pro also includes a 48MP Ultra Wide Angle Camera with a 120-degree field of view and 3cm Macro Mode, 8MP Hybrid Zoom camera with 30x digital zoom, and a 48MP Main Camera with optical image stabilization.

Image credit: OnePlus

The wide camera uses a 0.5-inch type Sony IMX586 image sensor with an F2.2 lens. The primary 48MP camera uses a 1/1.4-inch type Sony IMX689 sensor with an F1.78 lens. The primary camera also includes on-sensor omni-directional phase-detect autofocus. Further, the main camera can record ‘dynamic video,’ which is a form of HDR video.

The OnePlus 8 Pro is available now from a starting price of $ 899 USD. For much more information on the OnePlus 8 Pro smartphone, read our coverage of the camera’s announcement.

Gitzo updates Systematic tripod range with new materials, big feet and Easy Link sockets

05 Oct

Gitzo has introduced a new range of Systematic tripods that it says are more stable and stronger, and which feature new locking mechanisms for the leg sections. The latest models use what the company calls Carbon eXact for the leg tubing, which it claims offers improved ‘balance between rigidity and weight’. The Systematic range is Gitzo’s top end series and the tripods are designed for heavy cameras and long lenses. Larger feet have been introduced for the new models to prevent slipping and for making uneven ground more easy to rest on, and the twist-lock leg sections have been given G-lock Ultra clamps that Gitzo says are quicker and easier to use.

The company has also added a connector for the Manfrotto Easy Link system in a first for the Gitzo line-up. This threaded socket allows accessory arms and clamps to be attached to the casting of the tripod so reflectors, flash units, trays and other accessories can be held in place.

The new models will be priced from $ 799.99/£649.95 and a new range of monopods will start at $ 319.99/£214.95.

For more information see the Gitzo website.

Future Materials: Lightweight Carbon Fiber Architecture

11 Dec

[ By Steph in Conceptual & Futuristic & Technology. ]

carbon fiber architecture 3

The buildings of the future might just look as lightweight as a spiderweb, seeming as if they could blow away at any moment, while actually being incredibly strong. In the past, architects had to choose between delicate looks and durability, but the development of new composite materials unveils all sorts of possibilities. The c-LITH research project demonstrates the strength of digitally fabricated carbon fiber filaments stacked in small sections.

carbon fiber architecture 6

The team created a prototype that’s 14 feet tall and 8 feet wide at the base, yet uses only 30 pounds of material. It’s made of 143 wound carbon fiber filament ‘bricks’ that can be scaled up for architectural production. The use of carbon fiber has been fairly limited in architecture, as it usually comes in panels like those used for airplanes, and isn’t exactly cost-effective.

carbon fiber architecture 5

Michigan-based architecture firm Area used inexpensive cardboard molds to create the sections using carbon fiber filament pre-pregnated with epoxy resin to keep it malleable until baked. They built their own low-heat oven to cure the sections at 260 to keep the cardboard from catching fire. Once finished, the pieces were soaked in water so the cardboard could be removed.

carbon fiber architecture 7

The resulting bricks are stacked into a tetrahedral geometric shape, and pins connect the components, making them easy to assemble and disassemble. The designers see the possibilities as virtually endless, and it’s fun to imagine what could be made with this material at a larger scale.

4D Printing: Programmable Robotic Self-Assembling Materials

09 Dec

[ By WebUrbanist in Conceptual & Futuristic & Technology. ]

3d printed wood robots

Imagine a shelter that unfolds itself in the rain, flat-pack furniture that deploys without instructions or tools when exposed to water or a temperature-sensitive spoiler for your sports car that bends and twists as you race and turn – thanks to MIT’s Self-Assembly Lab, all of these designs may now be within reach.

This reactive approach adds a new dimension to objects made of wood, metal, carbon fiber and other materials, each fabricated according to patterns that in turn react to external inputs like low-tech robots. These creations can transform in shape, dynamic and responsive to customizable cues and environmental conditions – heat, cold, dryness and wetness can all be turned into catalysts for a conversion.

shape changing carbon fiber

Dubbed “four-dimensional printing” by Skylar Tibbits (Research Scientist in MIT’s Department of Architecture) due to the added element of time, this material strategy has proposed applications in various fields ranging from domestic (self-assembling furniture and toys) to vehicular (car spoilers and aircraft wings). Imagine as well, though, apparel that shifts to block rain or allows wind to cool you, or buildings that likewise open to ventilate or let in light and heat based on the weather.

shape change carbon fiber

The leap here is as much conceptual and experimental as it is intrinsically revolutionary. As Wired reports, “The tools Tibbits and company use are not especially novel. In the case of the carbon fiber projects, the manufacturing process is thoroughly two-dimensional. The team starts with a carbon fiber roll that follows the typical warp and weft pattern. A secondary material, formulated in Tibbit’s lab to respond to changes in temperature, is spot-printed on the mesh using a CNC gantry. As the carbon fiber is exposed to heat, the temperature-sensitive material changes shape and causes the sheet to deform in ways specified by the designer.”

More on MIT’s Self-Assembly Lab: “Self-Assembly is a process by which disordered parts build an ordered structure through local interaction. We have demonstrated that this phenomenon is scale-independent and can be utilized for self-constructing and manufacturing systems at nearly every scale. We have also identified the key ingredients for self-assembly as a simple set of responsive building blocks, energy and interactions that can be designed within nearly every material and machining process available. Self-assembly promises to enable breakthroughs across every applications of biology, material science, software, robotics, manufacturing, transportation, infrastructure, construction, the arts, and even space exploration. The Self-Assembly Lab is working with academic, commercial, nonprofit, and government partners, collaborators, and sponsors to make our self-assembling future a reality.”

10 in 1 Day: Chinese Homes 3D-Printed from Scraps Materials

05 May

[ By WebUrbanist in Architecture & Houses & Residential. ]

3d printed almost finished

Using recycled construction waste and rapid prototyping processes, a Chinese company is showing off how 3D printing technologies can be applied to building at astonishing new speeds and scales. More specifically: Winsun New Materials used a series large 3D printers to frame up 10 houses in 24 hours with a skeleton crew of builders.

These scaled-up printers mimic the additive approach their smaller plastic-extruding cousins, but deploy a mixture of glass fiber and scrap concrete instead.

3d printed house china

The function-first walls of these homes are designed to provide shelter via robust solid surfaces and structural support, all while minimizing materials. Built-in truss shapes (with spaces in between) are made to leave calculated gaps for the later insertion of plumbing, electrical, passive and active heading and cooling systems.

3d printed building construction

3d printed wall sections

In this initial run, the resulting prefab frameworks for ten residential structures were assembled in less than 24 hours and for just a few thousand dollars a piece. Securely enclosed by a small crew of builders, the weather-proof shells are then ready to be finished by other teams.

Given the pace of urbanization and construction within the country, it seems apt that innovators from China would be pushing limits like these, hopefully with more (and similarly eco-friendly) innovations yet to come.

House of Hemp and Blood: 16 Futuristic Building Materials

07 Oct

[ By Steph in Conceptual & Futuristic & Technology. ]

Future building materials main
Future buildings could be made of artificial human bone, hemp, bacterial byproducts or concrete that absorbs greenhouse gas emissions and lasts thousands of years. Innovations in building materials have led to synthetic creations that are stronger, lighter and more sustainable than those we already use, potentially leading to architecture unlike anything we’ve ever seen before.

Animal Blood Bricks

Future Building Materials Blood Bricks

Abundant and yet almost always wasted, animal blood is an unlikely – and grisly – possible base material for building bricks. Architectural graduate Jack Munro sterilized the blood, added sand and baked them together to yield a strong, traditional-looking brick that’s also waterproof.

Translucent Concrete

Future building materials translucent concrete

Litracon is a combination of optical fibers and fine concrete, produced as prefabricated building blocks for a translucent glass-like look with surprising strength. It’s handmade, so each block has its own individual pattern of light.

Bacteria Building Blocks

Future Building Materials Bacteria

Will bacteria build the walls of our houses in the future? Scientists have directed the creation of bioplastics, cellulose and other materials by feeding certain materials to specific varieties of bacteria. The resulting metabolic process produces solid, surprisingly durable byproducts that could be used for all kinds of processes. Bacteria might even create bricks that could be used for building on Mars.

Concrete That Lasts 16,000 Years

Future Building Materials Concrete 16000

Not only would the new concrete being developed at MIT drastically reduce the carbon emissions currently associated with the manufacturing of this material, it would also result in an astonishing reduction in the amount needed in the first place. That’s because it’s strong enough to last for an incredible 16,000 years. This concrete will not only be stronger, but also lighter and thinner, so large-scale, lightweight structures require far less material.

Hempcrete: Hemp Biocomposite

Future Building Materials Hempcrete

A new bio-composite, thermal wall material made of hemp, lime and water is not only eco-friendly but actually carbon-negative thanks to the amount of CO2 stored during the process of growing and harvesting hemp. It’s 100% recyclable, waterproof and fireproof and could be used for everything from walls and insulation to flooring. Once demolished, the material can be used as fertilizer.

SensiTile

Future Building Materials SensiTile

Sensitiles are made up of a light-conducting matrix embedded in a substrate, so that they redirect and scatter incoming light in a similar way as fiber optics. Shadow-producing movements around these tiles produce an interesting rippling effect, and the tiles absorb and ‘bleed’ colors.
