70-Gigapixel Photo of Budapest Offers a Great View

Supersized panoramic photos of cities are the flavor of the season. After Prague and Dubai, it’s the turn of Budapest to get a detailed online photo that you can zoom in and out of and play around with–almost like Google Earth.

The photo shot over four days has 70-gigapixels. If the finished picture is ever printed, it would make a a poster 156 meters (511 feet) long and 31 meters (101 feet) tall. The amount of paper it would take would cover two apartment blocks at least 10 floors tall.

To shoot the photo, two 25-megapixel Sony A900 cameras were fitted with a 400mm Minolta lens and 1.4 X teleconverters and placed on a robotic camera mount. 20,000 test images later, the file was processed to create a single interactive photo.

Check out the Budapest photo here. It’s a tad blurry and sometimes pixelated if you zoom in too much but still fun to play around with.

Gallery of Rephotography Shows WWII in Today’s Cities

On Monday we took a look at computational rephotography, a technique for making a new photo exactly match the point-of-view of an old photo. Today we take a look at a gallery of photos showing rephotography in action.

The pictures have been put together by Russian whizz Sergey Larenkov and posted on his Livejournal (yes, Livejournal is still around). Larenkov’s trick is to place old wartime pictures into modern settings, feathering the images to make them sit in the middle of modern life. Thus we see troops moving through a modern Vienna street, past stores and cars an tanks on the streets of Prague.

Some of Larenkov’s works are fascinating. The picture above shows Russian Red Army Marshall Georgy Zhukov on the steps of the Reichstag in Berlin. Zhukov conquered the city in the second World War, and now he stands amongst tourists. It’s pretty spooky.

Go grab a coffee and click the link. Not all of the pictures are as well executed as this one, but they are all interesting, and show that war is something that happens on our own streets, and not just in far-away places.

The Eye-Fi Pro and the iPad? Forget About it

After posting about the ShutterSnitch/Eye-Fi combo on Monday, which lets you beams photographs direct from your camera to an iPhone or iPad, I was sold, and I bought both. After using them for a couple days, it turns out that the Eye-Fi, in its Pro form at least, pretty much sucks.

I went for the Pro as it is the only one that works with RAW files. It is latest Class 6 (X2 in Eye-Fi terms) fast-transfer version, with 8GB memory, Wi-Fi and geo-tagging. It’s the best card Eye-Fi makes, and cost me €131, or a ridiculous $171. On top of this I bought the ShutterSnitch App for $8. I was now in for almost 180 bucks. What did I get for it? Not much.

Geo-Tagging

While the Eye-Fi Pro will geo-tag JPG images, it won’t tag RAW. This is because RAW files, although they use standard EXIF metadata (the information about the photo such as shutter speed and ISO), they put it in non-standard places. That’s fine. You can just shoot RAW+JPG in-camera and then use the desktop software to copy it across on import, right? No. There is no way to do this without resorting to third-party apps.

And if you use this (or any other) Eye-Fi card for geo-tagging, be prepared for slow imports. The way the Eye-Fi works is to gather data about the surrounding Wi-Fi networks as you shoot. Back at the computer, when you import, this data is sent up to the Eye-Fi servers and converted to location data. It’s how the iPod Touch works out your position in the Maps app, only done on Eye-Fi’s servers.

The problem is that to get this to work, you need to let your photos import over Wi-Fi. Even though the cards come with their own (pretty good) SD-card reader, you have to import over the network to get the geo-data, even if the card is in the card-reader. This, if you are shooting RAW and have more than a few photos, takes forever. Worse, if all your machines aren’t on a fast 802.11n network, you’re looking at hours to pull in the photos from a full card.

Compare this to the cheaper alternative, a GPS tracker. For around $50, you can hang a keychain-sized dongle on your bag, get real (and more accurate) GPS data and then combine with the photos later, in seconds.

Could I just import the photos with a regular card reader and drag them all into the Eye-Fi Center software? Nope. Done this way, it mysteriously stops recognizing the RAW format of the files.

Tethered Shooting

Done straight to the computer, transfers are rock solid, and fast if you have a fast network. Using ShutterSnitch, though, things are less reliable, and that’s being generous. I managed to get direct transfers working just twice over the past days, and even then not all the photos would make it to the iPad. And yes, I followed the instructions, and read the forum threads and did what I was supposed to do. But really, this should just work, and it doesn’t, making it useless as anything more than a novelty.

Direct Uploading

The other functions, like direct uploading to the web, work great. But as I would never send a photo to Flickr without at least some tweaking, it’s moot for me at least. It’s also speed-limited by your internet connection, which means that large files will take a while to upload and therefore drain the battery. Which brings me to…

Battery Life

In short, using the Eye-Fi for wireless transfer drains the battery fast. Geo-tagging doesn’t appear to cause a problem, but the strain of beaming images across the network sucks at the battery life. If you thought the days of removing the card from your camera to transfer photos were over, you’re dead wrong. It’s a good thing the card comes with its own reader.

More

There are more niggles. The Eye-Fi Center software, used for configuring the card, is clunky and annoying. For example, it pops up a dialog box every time you save a setting (and you have to save before you can move to a different tab). This needs to be clicked to dismiss it, every single time, and that gets old, fast.

The application also runs on Adobe Air and inexcusably installs the runtime on your computer without asking. The first thing you’ll know about it is when Air starts contacting Adobe’s servers and trying to update itself.

The conclusion seems to be that if you don’t shoot many images, or if you take crappy, low-res snapshots and send them straight up to Facebook, then one of the cheaper Eye-Fi cards might be for you. On the other hand, you can do all that with the cellphone you already have. If you’re a pro, or an enthusiastic amateur like me, the frustrations and limitations are so numerous you should probably look elsewhere. For wireless transfer, suck it up and use a USB cable. For geo-tagging, buy a cheap GPS-logger. Right now, the “Pro” version of the Eye-Fi line is half-baked at best.

Samsung’s Wi-Fi Camera Don’t Need No Stinkin’ Computer

Samsung has put a Wi-Fi radio inside its latest digicam, the ST80. The camera is pedestrian in almost every regard, from its ho-hum zoom range (35-114mm equivalent), through its 3-inch screen with just 230,000 dots to the too-big 14.2-megapixel sensor. But the saving factor is that Wi-Fi, which means that you can share your pictures without a computer.

In addition to email, you can upload images to Facebook, Picasa, YouTube and Photo Bucket. The touch-screen also lets you carry out basic editing first: you can crop, for example. The ST80 will also shoot 720p video at 30fps in H.264, and comes with an Boingo account to access Wi-Fi hotspots on the go.

This is the direction that more and more cameras will take. As smart-phones get better and better cameras, their connectivity becomes much more useful. With the iPhone, you can shoot video and stills, edit them and send them out to the world. Dumb cameras don’t even come close. Samsung has bets on both sides, with digicams and phones in its lineup, but we’re certain that those lines will blur more and more.

The ST80 will be available in September for $250.

Panasonic Announces 3D Lens for Micro Four Thirds Cameras

Panasonic is really into 3D. Not only will it sell you a big 3D television with which to watch the latest Hollywood head-spinners, it will soon sell you a lens which can be popped onto a G-series camera and shoot your own stereoscopic pics.

The lens is actually two lenses in a single, compact housing. When you shoot an photo or video, two pictures are captured simultaneously onto your sensor. Obviously this reduces the overall resolution of the resulting images, but with video this shouldn’t matter as the footage is down-sampled from the giant photo-sensor. This double-image (or video) is then turned into a 3D one in software, to be viewed on one of Panny’s TVs.

The lens has not yet been given a launch date or a price (other than a vague “end of the year”), so plenty of questions remain unanswered. Will cameras need a firmware update to use the lens? That seems almost certain. Also, how good will the stereoscopic effect be with the two lenses so close together? And I’m assuming here that the cameras will actually shoot 3D video: the press release only mentions still images, but who wants to view their photos on a TV screen?

Still, we love that Panasonic is making 3D an optional extra for its Micro Four Thirds system. It’s this kind of innovation that is currently leaving the likes of Nikon and Canon behind, and we’re all for it. And it shouldn’t be long before somebody hacks their way around the 3D format and lets us do something useful with the images instead of looking at them on a TV.

Six-Month Pinhole Exposure Shows the Sun’s Travels

The hypnotic image you see above is the result of a six-month exposure. Taking a photo that lasts half a year results in something that isn’t just a picture, but also a record of the weather and of the passage of the Earth around the Sun.

The image was made by Justin Quinnell, and comes from the simplest of cameras: a soda-can with a 2.5mm hole punched into the metal and a sheet of photographic paper hidden inside. Because photo-paper is so much less sensitive to light (in the darkroom you’d typically expose for 10-seconds or more), it needs to sit around for a long time to record an image.

The lines paint the path of the Sun as it slipped through the sky over Bristol’s Clifton Suspension Bridge (England). The dotted lines are caused by cloud hiding the Sun. The exposure was started on December 19 2007 and ran until June 21, 2008, the Winter and Sumer solstices.

This isn’t Justin’s only long picture. If you can stomach his Flash site, you can see a whole portfolio of the creepy, haunting pictures. The Clifton picture, though, is especially significant. Justin’s father died halfway through, so you can kind of pinpoint the date on the photo itself. It’s a wonderful memorial.

72 Ravishing Refractions [Photography]

ShutterSnitch and Eye-Fi: Wireless Camera Tethering for iPad

Back in May, we took a look at a ShutterSnitch, an iPad app that lets you receive photos wirelessly from your camera. Combined with an Eye-Fi wireless SD card, you can shoot away and have the photos pop up on the big screen in seconds. It’s like shooting tethered to a laptop, only about a zillion times more convenient.

So why are we revisiting the subject? Because it got a whole lot easier to use. Now, the tricky networking part has been simplified and you need only follow a few steps to get things up and running. The first time you do this, you’ll need to configure both the Eye-Fi card (using the Eye-Fi Center) if it is not already aware of your Wi-Fi network, and also the ShutterSnitch app (just enter the Eye-Fi username and password).

From there, you simply need to shoot, with one weird caveat: you need to create a “collection” in ShutterSnitch to receive the photos. That’s it. Now you can beam the photos across as you shoot.

There are plenty of things you can do within the application. As you shoot, the images are shown full-screen, with or without shutter-speed, aperture and histogram overlays. Once done, you can keep the photos in ShutterSnitch, mail them, organize them, upload to Flickr and pass them off to the iPad’s own photo-library, from where it can be sent off to any other photo-editing application you might have.

There is one big gotcha. You’ll need to have a Wi-Fi network running to make this all work: The Eye-Fi cannot beam direct to the iPad. That means you’ll need either a portable hotspot like the MiFi, be in a place where there is already a network, or create one using a laptop (which kind of defeats the point of this). I’m going to pick up an Eye-Fi card this afternoon and also investigate jailbreak solutions for ad-hoc network creation on the iPad. If it works, I’ll let you know.

Adapter Puts Nikon Lenses on Canon Bodies

Accessory maker Novoflex has a new lens adapter that will let you use Nikon F-mount lenses on Canon EOS bodies. It adds one big extra over previous versions: you get a ring to control aperture on Nikon G-lenses (those without an aperture ring.)

One of the great things about the little mirrorless cameras like the Panasonic G-series, the Olympus Pens and the Sony NEXes is that their currently meager lens line-up can be supplemented by other lenses old and new, just by using an adapter. SLRs, on the other hand, are pretty much stuck with the glass that was made for them.

An adapter has a thickness, and when you put one on a lens, you move that lens away from the film (or sensor). This stops the lens focusing at infinity (and will also allow it to focus a little closer). Thus, mounting a Canon lens on a Nikon body doesn’t work so well. The mirrorless cameras already have a lot of extra space to spare, so the adapters have room to fit. Novoflex has managed to get this ring thin enough not to cause focus problems.

The new EOS/NIK-NT adapter has an integrated aperture ring so that you can still set the hole-size. As G-series lenses are controlled entirely by electronics in the camera body, they need this extra to work on a Canon camera. Thus, auto-exposure (aperture priority) will work by actually stopping down the lens. Focus will still be manual, although infinity focus is maintained. If you have lenses with aperture rings, another adapter is available.

The problem is that there are plenty of great lenses for both Canon and Nikon, so we wonder why you’d need this adapter. For quick, fun experiments it will be great, but otherwise its hard to see the point. Especially when you consider the price, a rather odd $292.99.
