The Digital Holga, Or How To Waste A Million Pixels

digitalholga-770653

Take one high-end, medium-format digital camera back, and one plastic-lensed Holga film camera. Cut, stitch, and wait for a thunderstorm. Throw the switch and let the lightning flow into the Frankencam. It’s alive. Alive!

You may wonder why you’d do such a thing, but admit it, you’re intrigued. The trouble with digital photography is that it is so damned predictable. Cameras guess the exposure correctly almost all the time, the images are clean and if you don’t like it, you can try again, immediately.

Sticking a crap-cam onto the front of a high-quality capture device brings some unpredictability and some analog surprises back to photography. It’s the same thing as putting a Lenbaby, the low-fi, bendy lens that lets you send most of your pictures to blur, on the front of a full-frame DSLR: Fun.

And it’s exactly what Ted Dillard did when he hooked a Holga onto an Imacon 96 back. The Imacon was joined to a gutted Holga so that the 36 x 36 mm sensor sat in the film plane and the unit is triggered by a simple connection to the Holga’s hot-shoe. This sensor, although large, is still not as big as 6 x 6 film, so you don’t get the trademark dark edges on the pictures. Ironically, the bigger, better and more expensive the sensor you use, the more “Holga-like” (or “worse”) the pictures get.

If you’re thinking of doing this yourself, stop. The Imacon is impossible to get ahold of, and a new Mamiya digital back goes for well over $3,000. If you already have one, hack away. If not, try a cheaper solution, and just stick a Holga lens on the front of your camera. Flickr user Joachim Guanzon did it already and you’ll find the instructions, along with some great pictures, over at his page.

The $150 Space Camera: MIT Students Beat NASA On Beer-Money Budget

thumb

The $150 Space Camera.

Bespoke is old hat. Off-the-shelf is in. Even Google runs the world’s biggest and scariest server farms on computers home-made from commodity parts. DIY is cheaper and often better, as Justin Lee and Oliver Yeh found out when they decided to send a camera into space.

The two students (from MIT, of course) put together a low-budget rig to fly a camera high enough to photograph the curvature of the Earth. Instead of rockets, boosters and expensive control systems, they filled a weather balloon with helium and hung a styrofoam beer cooler underneath to carry a cheap Canon A470 compact camera. Instant hand warmers kept things from freezing up and made sure the batteries stayed warm enough to work.

Of course, all this would be pointless if the guys couldn’t find the rig when it landed, so they dropped a prepaid GPS-equipped cellphone inside the box for tracking. Total cost, including duct tape? $148.

Launch

Two weeks ago, on Sept. 2, at the leisurely post-breakfast hour of 11:45 a.m., the balloon was launched from Sturbridge, Massachusetts. Lee and Yeh took a road trip in order to stop prevailing winds from taking the balloon out onto the Atlantic, and checked in on the University of Wisconsin’s balloon trajectory website to estimate the landing site.

Because of spotty cellphone coverage in central Massachusetts, it was important to keep the rig in the center of the state so it could be found upon landing. Light winds meant the guys got lucky and, although the cellphone’s external antenna was buried upon landing, the fix they got as the balloon was coming down was close enough.

The Photographs

The balloon and camera made it up high enough to see the black sky curling around our blue planet. The Canon was hacked with the CHDK (Canon Hacker’s Development Kit) open-source firmware, which adds many features to Canon’s cameras. The intervalometer (interval timer) was set to shoot a picture every five seconds, and the 8-GB memory card was enough to hold pictures for the five-hour duration of the flight.

The picture you see above was shot from around 93,000 feet, just shy of 18 miles high. To give you an idea of how high that is, when the balloon burst, the beer-cooler took 40 minutes to come back to Earth.

What is most astonishing about this launch, named Project Icarus, is that anyone could do it. The budget is so small as to be almost nonexistent (the guys slept in their car the night before the launch to save money), so that even if everything went wrong, a second, third or fourth attempt would be easy. All it took was a grand idea and an afternoon poking around the hardware store.

The project website has few details on how the balloon was put together — but the students say they will be posting the step-by-step instructions soon. UPDATE: The instructions will be available for free, not $150, as earlier reported.

Extreme Pro: SanDisk’s Blistering Fast New Memory Cards

extremepro_cf_64gb_188_160

Putting a cheap memory card into a DSLR is like putting vegetable oil into the tank of a Ferrari*. The camera will write slower and you’ll saturate its internal buffer sooner. In short, if you have spent the money for a fast camera, then you should spend the money for a fast card.

I use SanDisk Extreme IV cards as they go great with my Nikon and have rather resplendent packaging (since reduced in size). They’re fast, to-ing and fro-ing data at up to 45MB/sec, which keeps my camera’s buffer free and means transfers from card to computer are also quick.

Today, these have been superseded by the Extreme Pro, a Compact Flash card available in 16GB, 32GB and 64GB sizes. They run at a blistering 90MB/sec, or double that of the previous cards. The catch is the price, which starts at $300 and rises quickly to $800. Extreme indeed.

Even the next model down, the Extreme III, has been ousted. This time the new range is simply called “Extreme” and offers rates up to 60MB/sec on cards from 8GB to 32GB and prices from $130 to $375. My lowly 4GB cards are starting to look a little old-fashioned.

*OK, it’s not quite the same. A slow card won’t actually trash your camera, but you get the point.


A Month With Honl Flash Light Modifiers

dance-flash-1

After we cheekily offered a how-to on making knock-offs of Dave Honl’s small-flash light modifiers, The Company got in touch. And surprise, they didn’t want to break our knees, or even our fingers. Instead, the folks sent over one of everything so we could try them out and compare to our rather excellent home-made solutions.

The Honl gear is a set of light-shaping tools for speedlights. Off-camera, small-light flash is a section of the camera market that has taken off in the last couple of years, thanks in part to the Strobist community and also, presumably, because the instant-replay on our digital cameras takes away the terrifying uncertainties of using lights too fast to really see. This popularity in turn has brought a demand for add-ons, but these have historically been for studio lights, or crazy expensive. The Honl range isn’t dirt cheap, but in the realms of photo gear it is a steal.

We checked out a gobo (or go-between, which blocks part of the light), a snoot (a fabric tube which lets you point light in a very tight beam), a speed grid (another directional tool which resembles a wad of plastic drinking straws in a box) and a set of color correcting filters. All of these are attached to the flash unit with Velcro, and here is the heart of the system: the Speed Strap, a semi-rubberized strap which wraps around the head and offers soft fuzzy velcro to the hard hooks on the accessories.

It works great. Above you see a picture taken as the sun was going down using a Nikon SB900 sitting on the ground and fired wirelessly using the Nikon D700’s built-in flash. The light is colored using a half CTO gel (CTO stands for color temperature orange — it warms up the flash light). The gels supplied come pre-cut and have velcro on two edges. When the sun is sinking you have to work fast and although the SB900 comes with colored gels and a holder, they’re all too fiddly. With the Honl gear you stick and rip, and it’s fast enough to keep up. In fact, if you leave the straps on the flashes, you pretty much don’t need to think about using the gear, which is the goal of any technology.

The snoots, gobos and grids are all perfectly competent. In fact, they’re probably no better at shaping light than what you could make yourself. The twist is that they are so reasonably priced that most people won’t bother with a trip to the hardware store. They are also sturdy. I’m no pro photographer, but neither do I pamper my gear. The review units are looking a little worn, but are holding up fine.

The real winner though, is the Speed Strap. A simple idea that makes swapping out light modifiers a breeze. Can you make your own? Hell yeah. We did, and we love the results. But if you just can’t be bothered, or if you want to just buy something that’ll work, the Honl gear will do the trick.

Teardown Reveals iPhone Camera Could Fit the iPod Touch — Barely

1696964330_c34b3a8b42_o

Apple could have put the iPhone’s camera in the iPod Touch, but it would have been a very tight squeeze, according to a repair company that disassembles iPods and iPhones.

That’s because the iPod Touch measures 8.5 mm thick, and the iPhone’s camera measures 6 mm, leaving a mere 2.5 mm of wiggle room for the iPod Touch. By comparison, the iPhone measures 12.3 mm thick, leaving plenty of space for its auto-focus camera.

“Unlike the Nano, the iPod Touch could conceivably support an iPhone-sized camera, although it would certainly be an engineering challenge,” said Kyle Wiens, CEO of iFixIt.

Apple on Wednesday released updates for its iPod family, including a new iPod Nano featuring a video camera and an iPod Touch with a performance boost. However, many questioned why the Nano gained a camera while the iPod Touch did not. Prior to the event, dozens of photos of third-party iPod Touch cases containing camera holes surfaced on the internet.

Michael Gartenberg, a tech strategist with Interpret, said Apple likely left the camera out of the iPod Touch to create “segmentation” of the products. This move would make consumers desire both an iPod Touch and an iPod Nano, he said.

However, iFixIt’s observations suggest that Apple may have left the camera out of the iPod Touch because it was technically too difficult to install. Prior to the event, a rumor report also said iPods with cameras might see a delay because of technical issues. This engineering challenge may have been the problem delaying a camera-equipped iPod Touch. That means an iPod Touch with a camera could be on the road map, and Apple’s engineers are probably devising a way to cram that camera inside.

Another question that arose from yesterday’s iPod event was why the iPod Nano can only capture video but not still images. iFixIt performed a teardown of the iPod Nano and discovered its low-resolution VGA camera is only 2.75 mm; the iPod Nano is 6.2 mm thick. The iPhone’s 6 mm camera, which must also account for a rubber mount, is thicker than the entire iPod Nano. In short, the low-resolution (640-by-480) VGA camera — with no focusing capability — would produce poor-quality still shots, which is likely why Apple opted to leave a still-shot function out.

Fifth-Generation iPod Nano Gets Disassembled

5quueqrckvys1wy5large
iPod repair business iFixIt has posted its teardown of Apple’s fifth-generation iPod Nano, which hit stores yesterday. Like previous Nanos, this model is tightly packed and held together with copious amounts of glue. iFixIt lays out all the steps for taking the Nano apart, but the company doesn’t recommend trying it.

More interesting is that taking apart iPods gives you better insight into some of Apple’s decisions. For instance, many of us are wondering, why no still-image camera in the Nano? Steve Jobs said the Nano is so small it couldn’t fit a sensor for a still-image camera. Kyle Wiens of iFixIt confirms this is a valid explanation.

“The camera in the iPhone is thicker than the entire Nano,” Wiens told Wired.com. “The AF lenses really bulks it up.”

Makes sense. Hence, there is no option to shoot stills with the Nano, because the low resolution of the 640-by-480-pixel VGA camera would likely make photos look like garbage, which Apple wouldn’t be happy with.

Check out more nude images of the Nano below the jump and the entire teardown process at iFixIt.

A Tale of Two iPods: Why the Touch Has No Camera

two_ipods_680x

Apple’s decision not to include a camera in the new iPod Touch is somewhat surprising. After all, there is already a perfect camera for the job, and it sits inside the iPhone. That Apple included a video camera inside the iPod Nano makes this more inexplicable still — the Apple of today is clearly happy to put cameras into its media players (unlike the first iPhone, whose camera was so poor we thought it was just a petulant capitulation to cellphone norms).

Leaving the camera out is also a clear signal not to upgrade the Touch, as — apart from a larger 64-GB model — the only hardware change is a juiced-up processor, making the iPod Touch run faster like its older brother the iPhone 3GS. Perhaps Apple is putting the Touch on a two-year update plan like the iPhone, letting people keep their pocket computers for a little longer than usual.

It’s also likely that Apple wants to maintain enough differences between the Touch and the iPhone to give people plenty of reasons to buy the more expensive device.

Had the Touch included a camera, I would be knocking on the store doors right now to buy one, along with 64 GB ready to be filled with photos and video.

So the excitement falls to the Nano, which, sports a new shiny coating, a 640 x 480 video camera (no stills) and a larger screen on the outside, and an FM radio on the inside with a Tivo-esque live-pause feature. The radio itself is odd enough, and the first to be included in any iPod. More on that in a moment.

The Nano’s video camera was introduced with reference to Flip’s own tiny, no-zoom camcorder. There are two Flip camcorders at the 8-GB Nano’s $150 price: the 2-GB Mino and the 4-GB Ultra. To get 4 GB and 8 GB you jump to $200. The 16-GB Nano costs $180. Why would somebody buy a Flip? The easy, one-button recording, perhaps (with the Nano, you need to go to a menu item to open the video camera application), but that’s it. Take a look at the sample videos at the Apple store and you’ll see that the Nano’s quality is easily “good enough.”

There is another surprise in there, too. The tiny Nano frame has a chip big enough to add real-time effects to video. Gimmicky, but as we guess this is aimed at the teenage market, a nice feature.

The Nano is the fitness iPod, too, and in this guise it makes another piece of hardware obsolete: the shoe-mounted Nike+ dongle. The Nano comes with the Nike+ software, with workout history, power songs and the like, but the accelerometer now works as a pedometer, counting your steps to flab-loss. You can also connect it to a Nike+ iPod-compatible cardio machine via the dock connector.

One mystery remains, though. Why would Apple put an FM tuner into an iPod, something it has refused for almost 10 years? The answer comes with iTunes-Tagging. In addition to live pausing of the radio stream (and rewinding up to 15 minutes through the buffer) you can tag tracks by hitting the center button. If a radio station supports it, the song info is saved and later you can see a list in iTunes alongside, you guessed it, the option to buy the song. Of course, the fact that the new Zune HD has an HD radio inside may also have influenced Apple’s decision.

So now I’m torn. Do I buy a new Touch to replace my current model which has a loose headphone connection, or should I get the Nano, with its video camera and sport-friendly features? If Apple had piled the features onto the Touch, the decision would be made, and Apple would have $400 of my money. As it is, I think I’ll wait.

Clunky, Chunky ‘Sports Camera’ Launches at Wrong Time

medion_s47000

Medion, the commodity manufacturer of MSI Wind clone, the Akoya Mini (aka the last remaining Gadget Lab hackintosh) has just announced a new “sports camera”. The Flip-style video camera makes its appearance with unfortunate timing, and despite being a 720p hi-def camcorder, it will still be compared to the new video-shooting iPod Nano.

The rather ugly box packs in a lot of high and low-end features. The h.264 codec lays down video, which can be captured with a 2x digital zoom (don’t be tempted to use it). The camera will also shoot stills, although the 1MP sensor will make this less than worthwhile. You do get a decent maximum aperture of ƒ2.8, a top shutter speed of 1/2000th sec, and an HDMI-out port. You do not get any SD card, and as the internal memory is a mere 90 MB, you’d better add that to the price.

The Medion® Life® S47000 Digital HD Sports Camera, to give it its full name, will cost £100, or $165, putting it smack in the middle of the Nano’s price range. And one more thing: The Sports Camera is also a Nano-killing MP3 player.

Leica X1 Puts DSLR Sensor in Tiny Compact Body

leica x1

More interesting to most people than the new M9, not least because of price, is Leica’s new X1. Think of it as a miniature M-series camera, only with a single, fixed lens.

The 12.2 megapixel camera isn’t cheap – the list price is $2,200 – but it should do most of what the M9 does. First, that lens. You can’t change it, and it doesn’t zoom, but as most Leica-M users stick to a 35mm lens anyway, the Elmarit 24mm f/2.8 Ashperical should do the trick. The math nerds will have noticed that 35 divided by 24 is 1.46. This betrays the X1’s huge sensor. It is bigger than the micro four thirds sensors, and essentially puts a DSLR-sized (APS-C) chip into a compact camera.

The numbers: ISO runs from 100 to 3200, shutter speeds up to 1/2000th of a second, and there are 11 focus points plus face-detection. There is also a pop-up flash and a 2.7-inch, 230,000 dot LCD screen.

What the numbers don’t tell us is that, in addition to the usual auto-modes, the X1 has manual aperture and shutter-speed dials on the top plate, and that when you buy it, it comes with a license for Adobe’s Lightroom software, a very welcome addition as bundled software is usually awful.

The one thing missing is an optical viewfinder, but following the trend set by the Olympus EP-1, you can buy one to slot into the hot-shoe mount up top. It’ll cost you, of course (another $350), but if these optional finders become popular then a third-party market might grow to sell them, just like in the olden days of ‘finder-less “rangefinders”.

We’re looking forward to this. It could actually be the true spiritual successor to Leica’s now anachronistic M-series.

The X1 will be arriving in January 2010.

Leica M9: 18 Megapixels, Full-Frame Sensor

m9-black

Along with Palm and its little Pixi phone, Leica decided that yesterday would be a great day to bury news under the twin stacks of Apple iPod announcements and Beatles releases. Leica in fact announced some of its most significant products for years. First, the M9.

The M9, sequel to the M8, is the company’s first full frame digital rangefinder. The 18 megapixel CCD sensor, developed by Kodak, is the same size as a 35mm frame, which means the M9 can use all of Leica’s M-lenses at their originally intended focal lengths. It also consigns the M8 and it’s crop-sensor lenses to the curiosity shoppe of history.

The body itself has seen a few tweaks in button positions, but the real changes are internal. The Kodak sensor adds new micro-lenses which help corral the light onto the pixels — all sensors have these tiny lenses over the photo-sites, but rangefinders are a special case: the rear of the lens is so close to the sensor that the angle of incidence is particularly sharp. These new micro-lenses bend the light to fit. The glass sensor cover has also been redesigned and now cuts out infrared light. Previously Leica’s workaround was to add a filter.

The shutter, too, is new, and is “microprocessor-controlled”. Leica says that it is “particularly silent”, which, given the legendary whisper-quiet M-series shutters of old, is probably true. It runs up to 1/4000th of a second and offers a maximum flash sync speed of 1/180th/sec. Stick it on your Christmas list now.

And that’s it. What? You want to know the price? $8,000, but Amazon will let you have it for a mere $7,000 when it ships.
