Circular Logic: “Endless Runways” Rounded to Save Energy, Time & Space

02 Apr

Designed to reduce real estate needs for runways in ever-more-crowded cities, this “endless runway” system encircles a central terminal building and lets multiple planes take off and land at the same time.

Developed by Dutch scientist Henk Hesselink, the two-mile-circumference shape also lets planes land or take off in alignment with the wind (rather than fighting crosswinds) since they can line up with any point on the strip.

In theory, the system would improve the flying experience for both passengers and pilots, making for smoother departures and arrivals. They would also save energy and space, increasingly an issue for once-suburban (or rural) airports now encroached upon by growing cities.

Critics have expressed skepticism regarding the difficulty of landings and take-offs in such a setup, but big backers seem to believe in the potential. Also, even if not immediately feasible, increased automation could make it increasingly viable over time, since computer systems can coordinate ideal landing and arrival trajectories for optimal safety and comfort and across multiple planes.

Each such setup provides the length of three airstrips and could be deployed or at least tested at scale in Europe soon — participating backers include the Netherlands Aerospace Centre (NLR), along with DLR Germany and ONERA in France.

From the designers research report: “The results of the literature survey in this document are promising and suggest that a circular runway can be developed with current and expected technology. Today’s aircraft characteristics allow to take off and land with speeds and low altitude bank angles compatible with the operation on a circular track. The Endless Runway fits in future concepts that specify improved planning of operations, new navigation equipment, and intermodal transport.”

Impossible Photography: 15 Reality-Bending Images Defy Logic

12 Apr

A floor is a ceiling, a lake is made of shattered glass, carpets of grass cascade over the edge of the world and buildings sprout wheels and wander away in the fantastically surreal world of Erik Johansson. The photographer has spent much of the last decade refining his reality-bending image manipulation techniques, combining dozens of real photos to create effects that are often hyperrealistic yet physically impossible. As unlikely as it may seem, Johansson uses no CGI, stock photos or digital illustrations in his work – each image is a complex collage of his own photographs, captured on his Hasselblad HD5-40 camera.

On his YouTube channel, the artist offers behind-the-scenes videos for many of his works so we can see just how each one is assembled. For his newest piece, ‘Impact,’ Johansson carefully cut four massive mirrors into fragments, arranged them in a field and photographed his model standing among them in a kayak. Photos from this shoot are ultimately blended with images of a lake and additional studio photos of cracked mirror shards.

Depicting just about every step the artist takes during the process, the videos are just as impressive as the final images and make it clear that the arduous process requires many hours of retouching. Johansson even leaves in the parts where he experiments with various effects and ideas that don’t make it to the final version.

As he explains on his website, Johansson is interested in capturing ideas rather than moments, but with the goal of making each one look as realistic as possible, saying “The only thing that limits us is our imagination.”

Hammock suspension adds extra protection in the Kontrast Pro DSLR Backpack from Case Logic

25 Jul

Bag manufacturer Case Logic has launched a new backpack that features a hammock system, suspending a DSLR with lens attached within the space in the middle of the bag. The company claims this adds extra protection as less of the camera body is in direct contact with the structure of the bag. Read more

Case Logic SLRC 205 Sling Camera Bag Review

Case Logic SLRC 205 Sling Camera Bag Review

If you’ve ever bought a case for a tablet or a hard drive then you’re probably familiar with Case Logic products. The ubiquitous logo is hard to miss in the accessories section of computer and electronics stores.

Case Logic SLRC 205 Sling Camera Bag Review

What you may not know is that Case Logic also make some very good camera bags, up there in quality and design with established brands such as Lowepro, Crumpler, Kata and Think Tank.

So when David from Love Cases got in touch asking if I’d like to review a camera bag sold in his store, I selected the Case Logic SLRC 205 sling style backpack to test out.

Why a sling bag?

The type of camera bag I use depends on the nature of the shoot and the amount of equipment I need. For example, I like to use my ThinkTank Retrospective 20 on portrait shoots. It’s a shoulder bag into which I can easily fit everything I need. But, it’s a heavy bag and all the weight is on one shoulder. After a while it hurts, and becomes uncomfortable to walk with – that limits its use to shoots where I don’t have to walk very far.

Sling bags are ideal when I need to walk some distance to arrive at the location of the shoot. I can put my gear in the bag, then take out what I need when I arrive.

I like to use a Black Rapid RS-Sport camera strap, which leaves my camera hanging down by my right side ready to use. If I have a sling bag I can keep it on my back while I shoot, held in place by the straps so it doesn’t move around. I don’t have to worry about where it is, or someone stealing it if I put it down.

However, I don’t use sling bags in one way they are intended. I never bring them around to the front to remove gear, as I find they are so high on my body that it’s an uncomfortable process. Not everybody feels this way, I’m sure. This photo shows where the camera bag lies when you swing it around to the front.

The Case Logic SLRC 205 bag

I’ve used this Case Logic sling bag on several shoots and I’m very pleased with it. It would suit me better if the main camera compartment was a little bigger, and it would be nice if it had a waterproof cover. But apart from that I’m delighted with it.

Features

I really like the design of this camera bag. It has a number of well thought out features that make it easy to use.

Main camera compartment

This is for your camera and lens. Case Logic use a hammock system to support your camera. There is a flap with a hole in it at the top of the compartment, and you can place the lens through the hole and rest your camera on top. It keeps your camera ready to hand and provides extra protection if you drop the bag.

It’s a great idea, but the only drawback for me is that the compartment is too small for my camera, (an EOS 5D Mark II), when the hammock is in position. In terms of size, this bag is best suited for small digital SLRs or mirrorless cameras.

However, if I fold the hammock down (it is supported by velcro) I can fit my camera inside. The camera rests on the lens in this position, so I attach the lens hood to prevent the lens cap being dislodged by rubbing against the side.

Small side compartment

This is big enough to store another lens or accessories. I use it for my Black Rapid camera strap and a small prime lens. It’s not designed for another body, so if you want to take two cameras on a shoot then you’ll need another bag.

Memory card storage

On the other side is a zipped compartment that opens to reveal memory card space storage.

Wallet compartment

You can put anything that fits in here, but it’s ideal for a wallet. It’s hidden behind the velcro flaps used to support a tripod, making it virtually impossible for someone to steal the contents unnoticed.

Mobile phone compartment

One of the straps has a small flap ideal for storing a small mobile phone. My iPhone 3Gs fits inside, just. If you have a larger phone than this you’ll need to find somewhere else to keep it.

Tripod support

There’s a hook-n-loop strap to support a tripod. It’s a nice idea, best suited to small, lightweight carbon fibre tripods rather than heavier models.

Bag quality

The quality of this bag is excellent. The outside of the bag is made from hard-wearing nylon. The zips are strong and durable and have tags marked with orange thread, making it easy for you to see them.

There are three strong, conveniently placed, handles that make the bag easy to pick up. The shoulder strap is well padded and nice and wide to spread the weight. The interior is bright yellow, so it is easy to see your black accessories such as lens caps. The support straps come with velcro tabs so any unused straps don’t dangle down.

Conclusion

This is a high quality camera bag ideal for anybody who takes a minimal amount of equipment on a shoot. It is most suited for photographers who use small SLR or mirrorless cameras. It is comfortable and easy to use. The only drawbacks are the size (if you have a large camera body) and lack of a waterproof cover.

Thanks to David from Love Cases for supplying the bag for review. Love Cases is a UK based company with international delivery. You can also buy the Case Logic SLRC 205 from Amazon.
