of the Google Wave platform.
Maybe users didn’t see the point in Wave, or maybe Google didn’t explain it well to the masses, Google’s reasoning behind unplugging the software from the cyberspace is that it “has not seen the user adoption we would have liked.”
Fortunately, instead of Google laying the Wave team off, they will instead be assigning them to other projects inside Google.
Personally, I thought Wave had a good amount of potential but had a messy interface and was fairly confusing for a basic user, such as installing some apps/extensions.
In the race to satisfy adrenaline junkies need for speed and for something new and dangerous, we present you with an extraordinary new form of downhill racing, where the rider becomes one with his steed, where the biker actually becomes the bike!
There are no motors so gravity is your go juice and to activate the rear brakes you need to squeeze your knees together like a mobile ThighMaster. Your legs are strapped to the rear gear so there’s no bailing out but there is a fender to fend off fanny friction should you sit too low. We recommend wearing as much padding and body armor as possible because there’s no way to catch yourself if you start to fall but hey, before you get going too fast, we bet you could pop a few wacky wheelies!
Sigma APO 200-500 F/2.8
Perhaps the most “sensible” of the items presented in this list, this is nevertheless one of the heftiest tele zoom lenses for SLR cameras around. While the zoom range of 200-500mm is nothing new or exciting, it’s the maximum aperture of an incredible f/2.8 throughout the focal range that makes this such a special lens.
While a lot of tele lenses have a distinct cannon barrel look, Sigma have apparently done all they can to enhance that trait, giving the lens a leafy green finish. The end result is an extremely fast tele zoom lens that could easily be confused with a surface-to-air missile launcher.
Zeiss Apo Sonnar T* 1700 mm F4
For people who have been into photography for a while, the name Carl Zeiss means top of the line optical quality, usually with a matching price tag. While continuing to produce their top-of-the-line optics for various camera systems, Zeiss have more recently also begun cooperating with Nokia and Sony, making optics for their mobile phones and digital cameras.
Two years ago, the company presented a remarkable one-off tele lens, reportedly custom built for a wealthy Qatari. Weighing in at 256 kilos, it’s is a 1700mm f/4 lens designed for medium format (which roughly equals 750mm in 35mm SLR format). The monster bears more than a fleeting resemblance to a jet engine; given the size the ‘super tele lens’ labeling on the side seems a little superfluous – it isn’t very likely that it would be mistaken for an average 70-200mm, after all.
The little black lump at the end is your average 6×6 medium format camera, in itself a quite bulky piece of equipment, but completely dwarfed by the Zeiss lens. Upon it’s unveiling, it was said to be the largest non-military tele lens in the world. One wonders what the largest military tele lens might look like.
Drawing from their experience in manufacturing large telescopes and instruments for astronomical sciences, Zeiss had to develop an entirely new focussing system, Due to the massive size of the glass elements, the lens had to be equipped with extremely powerful focussing motors, capable of moving all that heavy glass around. The rear end of the lens has a dedicated LCD monitor built in to display focussing distance, aperture etc. No price has been published, but Zeiss hinted at a price of at least several million Euros.
The intended use for the lens is reportedly “antelope photography”. This doesn’t immediately strike one as the kind of kit you want to bring along on a safari to photograh fast moving and easily startled animals – hiding in the bushes is certainly off the agenda – but the uncompromising construction is said to allow the lens to autofocus as fast as a ‘regular’ telephoto lens.
Polaroid 20×24” Camera

The average film camera has for the last 50 years used either 120 rollfilm or so-called 135 film, 135 being by far the most commonly used type. Each frame of 135 film is 36×24 milimeters, while the average consumer dSLR camera today has a sensor size of approximately 60% of this, around 23×15 milimeters. The sensors in digital compacts are much smaller still. Within this tiny space, the camera and its lens has to compress the vast amount of detail visible to the human eye. The resulting replications of reality are far from perfect, they can’t be.
One way of partially overcoming this problem is quite simply to use larger film formats or digital sensors. Within the digital realm, the 48x36mm sensor size available in certain medium format digital backs is pretty much as large as it gets without substantial R&D resources (like what a major corporation, national government or army might have at their disposal).
In film, things are a bit simpler. While constructing huge digital sensors is a challenging task, creating a huge sheet of film or photographic paper is really – simply put – just a matter of making it bigger than usual, and building a camera large enough to house it.
The biggest ‘instant’ camera I know of is Polaroid’s 20×24” behemot. It’s 1.5 meters tall and weighs in at 106 kilos. The Polaroid paper sheets used in this camera is, as the name implies, 20 x 24”, which equals 50×60 cm. Keeping in mind that the aforementioned 135 film is a mere 3.6 x 2.4 cm, it’s easy to see why such a larger-than-life camera would be capable of producing prints of far superior detail compared to smaller formats.
A number of these cameras are available for hire, complete with a dedicated studio space, in San Fransisco, New York and Prague. Following Polaroid’s recent announcement that they will completely cease the production of their signature instant film, there is a certain risk that these cameras will be destined for the museum soon.
Seitz 6×17” digital panoramic camera
Instead of the common digital camera sensor which records the entire scene at once, the Seitz 6×17” uses a scanner to literally scan the view through the lens. The end result is 160 megapixel images in a panoramic format. It does the job a bit faster than your average flatbed scanner though, recording a full-sized frame (21 250 x 7500 pixels) in two seconds. It’s big, it’s heavy (5 kilos if you wish to use it outside a studio) and quite silly, but it turns out huge, amazing photos – and it should, costing as it does $42 000.
Swedish camera manufacturer Hasselblad (or “‘blad” as they are often called) has for a long time been ranked among the very best when it comes to cameras. Indeed, NASA’s space programme chose Hasselblad as their camera provider, and three Hasseblads where carried aboard the Apollo 11 mission, perhaps the company’s most famous feat.
Priced at around $40 000, a Hasselblad H3DII with a 39 megapixel backpiece is one of the most expensive photo kits available in ordinairy retail sale. It’s fairly large, fabulously expensive and capable of creating huge, extremely detailed image files with its 39 megapixel, 48x36mm sensor.
For photographing your cat, you can probably make do without this camera, but if you’re shooting supermodels for Vogue, you might just need a camera of this caliber. If you ever watch TV shows like “Top Model”, there’s a fair chance you’ll see a ‘blad involved in a shoot every now and then.
Canon EF 1200mm f/5.6L USM
While the 1700mm lens mentioned earlier is all fine and dandy if you’ve got a truck to mount it onto, some may prefer a more lightweight, nimble sollution. Weighing a mere 16.5 kilos and being only 83 centimeters long (without the bucket-like hood), this delicate little flower will nevertheless magnify faraway objects (or perhaps more relevant, faraway people) to a degree that will leave little to the imagination. To my knowledge, this is the longest focal length available to autofocus SLR cameras without using any extra magnifiers.
Due to its size, limited area of use and robust price tag, it has only been available from Canon built to order, and to date they have apparently produced fewer than 20 samples of this lens. The company recently announced that they would be slashing the 1200mm from their catalogue, so if you want one, better be quick about it.
The suggested price of the lens upon unveiling in 1993, converted to present day money puts it at apx. $120 000, or the cost of “a small sports car” which is the most common price comparison given for the lens.
The Gigapxl Project
Launched by physicist Graham Flint, the Gigapxl Project set about creating a camera system that would allow the creation of photos with billions of pixels (or thousands of megapixels if you like). The Gigapxl Project employs a large format camera with 9×18” film sheets to shoot big panorama photos of places of interest, primarily in the USA.
The film sheets are then scanned using a highly sophisticated technique, resulting in digital files that contain the equivalent resolution of several gigapixels. Though the original aim was to reach a single gigapixel (1000 megapixels), the project website now claims it is able to create images with a resolution of aproximately 6 gigapixels.
Nowadays, camera manufactureres like to stick very dense sensors into tiny consumer cameras with mediocre optics, which results in images that despite the 12 or 14 megapixel resolution aren’t really any better than 4 megapixels. It’s a way of cheating customers who don’t know much about digital photography as most people seem to think that more megapixels equals better photos, which is a truth with great limitations.
It would be easy to think that the Gigapxl Project is much the same, just a whole lot of pixels wasted on creating huge digital files that contain little in terms of actual details. However, at the project website, it’s made very clear that the technology and knowledge put into these photos means that the 2, 4 or 6 gigapixel photos they produce are in fact as detailed as their pixel size suggests. But why take my word for it? Check out the amazing images in their gallery for an idea of what I’m talking about!
A pinhole camera is perhaps the simplest kind of camera there is. You make a tiny hole in an otherwise light-sealed container, but in a sheet of film or other photo-sensitive media, point it towards what you want to photograph and let light pass through the hole for a set period of time. The reflected light will, just like the light reflected through the lens of an ordinairy camera result in a photo, be it through a digital sensor or on a piece of film.
But it could also be built out of a box truck, which is exactly what an inventive bunch of spaniards and americans did. By drilling a hole in its side and attaching huge sheets of photographic paper (100×30 cm) to the inside of a truck, they created a huge mobile pinhole camera.
“The Great Picture”
But why stop at a truck, when you could convert an entire airplane hangar into a pinhole camera? While the Cameratruck above is touted as the world’s largest mobile camera, this hangar is certified by the Guinness Book of Records as the largest camera in existance, albeit immobile.
It’s basically an old hangar building at the disused El Toro Marine Corps Air Station in Southern California, which has been made light tight to ensure no light gets in except through the little pinhole in one of the hangar’s sides. To create the image alluringly described as “The Great Picture”, a huge sheet of made-to-order canvas was suspended inside the hangar and coated in 80 litres of Liquid Light, making it photosensitive.
The exposure time of the world’s largest camera was set to aproximately 35 minutes, after which the canvas was chemically developed (in a pool of 2300 litres of developer – photography at this scale does not come cheap!) into the world’s largest photo, 313 square meters (3375 square feet) in size.
Compare that to a standard 135 film frame, which you might remember from earlier on in the article is 36×24 milimeters, equalling 8.64 square centimeters, or 0.00864 square meters.
Wishing you could get a little more intimate with your computer? Swedish researcher and entrepreneur, Martin Magnusson has created a wearable computer that stays very close by. The concept behind it is really quite simple, but the engineering within is what makes it so clever. First, Magnusson bought a cheap CD case, ripped out the CD pockets and replaced them with velcro, causing the case to open like a book for all of the components. It’s then attached via a shoulder strap so you don’t have to worry about holding it up constantly or the computer falling off. Magnusson then hacked a pair of Myvu media glasses, connected with his home made machine based on a Beagleboard single computer. In order to get online, Magnusson uses bluetooth connected to his iPhone. The Beagleboard is powered using four AA batteries, allowing it to last around three hours, and if that isn’t enough time, he believes you could add battery packs to last all day if need be. “A computer is a window to the virtual world, but as soon as I get up and about, that window closes and I’m stuck within the limits of physical reality.” Magnusson says. “Wearable computers make it possible to keep the window open. All the time.”
A more realistic scenario would be for Magnusson to build a Bluetooth wireless transmitter for his Myvu glasses, projecting his iPhone display to the glasses and using that as thecomputer. All other hardware is really unnecessary, but a fun project I’m sure if you are going for the cyborg look.
Panasonic has kick started the “First Year of 3D Era” thanks to the development of a digital twin-lens system that allows regular DSLR cameras to capture in 3D. Belonging to the LUMIX line, the new G Microsystem will be interchangeable, adding an entirely new dimension to traditional photography. Simple for the end user because of the flexibility of interchangeable lens cameras, this will provide “instant 3D shooting, without distortion or time lag between left and right images.”
Details remain scarce, no release date or pricing information was announced. We do know, however, that it will be compact in size, and will be released by this years end. Panasonic also revealed the first consumer 3D video camcorder.
When you want to enjoy some cool wireless broadband but the overage of your area is not that good you gotta invent something else to help you achieve the strength of the signal. For this you can use anything you are capable to find. Barbeque grilles, tin foil covered umbrellas, frying pots and cooking pans – all can do for this. You can see all those and even more that are being actually used by Russian mobile phone users in their search of mobile connectivity. Maybe you have some cool ideas too? So please share them to make our life more convenient.
Are you tired of plane conservative gray color all over the air plane you are boarding. It can really be dull and annoying. If you are afraid of flying this surely does nothing to help you overcome your fear.
Maybe air liners should consider adding a bit of creativity to their plane’s appearance. The results could be very amusing and really fun. I wouldn’t mind if the air plane stuck his tongue out to greet me!
