July 09 Yosemite Extreme Pano Video
The Microsoft Pro Photo Summit is going on this week. Scoble is doing some interviews. He just posted a good one with Greg and Eric from xRez speaking about the Extreme Pano project I described in my previous post. Greg demos some of the initial stitching results streaming onto a Microsoft Surface. June 03 Yosemite Extreme Pano Project
The plan that the xRez team hatched went beyond simply taking high resolution photographs of each wall in succession. Rather, they wanted to photograph the entire valley in as small a time window as possible. Doing this means that all of the images would have very similar lighting, thus any composite image that is generated will be more seamless. The goal is to create a seamless mosaic of all of the valley walls. Because the source images are shot from multiple vantage points, the result will be a 'multi-perspective' mosiac. To do this, xRez will project the images onto a 3D model of the valley and re-render the images using a virtual flying 'slit-scan' camera. I did a quick web search for examples of this technique. I didn't find a good example for 3D terrain, but I did find some of street-side scenes: Capturing all of these images simultaneously required lots of gear and lots of bodies. xRez got 70 photographers to donate their time last weekend (Peter Duke has a great Flickr set of some of the Yosemite shooters). They also rounded up a good set of sponsors. Canon loaned G9 cameras, Bogen loaned tripods, Lowepro donated their Flipside 300 packs and Gigapan loaned their robotic pan tilt heads. For the shoot each G9 was outfitted with a Canon TC-DC58C tele-convertor and a home made lens hood (see Gavin Farrell's shots of the final setup here and lineup of packs here). The Photosynth team at Microsoft was happy to help out with financial sponsorship and members of my team flew down with our large panorama rig to man one of the 15 shooting locations. Most of the photographers hiked into their locations. Fortunately, the gear I described above was nice and portable. I believe that the longest hike was done by the team that went up Half Dome. All of the photographers were in place at 1PM on Sat., May 31, and everyone started to shoot simultaneously. Our rig, pictured to the left, didn't lend itself to hiking, so we drove it up to Glacier Point. Some technical details of our gear: Meade telescope donated a telescope mount from which we removed the optical tube. We put in its place a Canon 1Ds Mark III and a 100-400 zoom lens. This setup was controlled by a laptop. We parked ourselves at Glacier Point for 1.5 hours. (I apologize to the tourists there that day for whom we denied the sweet corner spot) Over that time, we shot 680 x 22MPixel images at 400mm. Accounting for some overlap between images, this should result in a 10 Gigapixel composite. Since this is just one of 15 locations, the final result of everybody's photos should yield many 10s of gigapixels. Everyone converged back at camp later that day for a nice catered dinner and keg by the campfire. From the discussion at dinner, all of the gear performed very well. It sounds like there might be 100% success rate for the shoot! Kudos go out to xRez for managing the logistics of this so well and Gigapan for the reliability of their pre-release units. I'm really looking forward to the final product which should be ready sometime in late summer. So stay tuned to the project page here. Also check out the xRez Yosemite Shoot Flickr group for photos of the weekend. -Matt March 27 Pacific Northwest PanoramasOver on the Windows Vista Blog, Brandon LeBlanc has posted a really good set of panoramic images from around the Pacific Northwest. This might be the best example yet of what the stitching technology in Windows Live Photo Gallery is capable of. See the pictures here: http://windowsvistablog.com/blogs/windowsexperience/archive/2008/03/25/panoramic-stitches-from-around-the-pacific-northwest.aspx For more info on stitching in Windows Live Photo Gallery see our previous blog entry. To make your own panoramic images, try out Windows Live Photo Gallery yourself: http://get.live.com (! it's free !). Brandon is threatening to create a video tutorial about his shooting technique - we'll be sure to link to it when it becomes available. -Matt March 25 Amazing new Gigapixel imagery from xRezOur friends over at xRez have written an interesting article that appears today in vrmag. The article describes a very large photography project that xRez did for move.com (a real estate web site). As Greg recounts in the article, move.com hired them to shoot Gigapixel "slice of life" images from around the country. All told the project yielded 1.08 petapixels of new imagery.
The links above contain some amazing new imagery. The "slice of life" aspect of this photography really comes across in this image of Gas Works Park in Seattle. Another thing that I take from this article is that xRez has demonstrated that rapid production of large immersive imagery is now feasible. One field that I think could benefit from this is Internet based journalism. The Internet news site that can publish this type of imagery in near real-time would be much better able to tell certain stories. xRez's shot of the Minneapolis I35W bridge taken 3 weeks before it collapsed brings this point home. It turns out that this is just a small sampling of the imagery captured for move.com. Unfortunately move.com has not yet published the remainder. A quick search yields this article from July 2007 where "Gigapixel Neighborhood Views" were announced. I'm hoping to see these show up on their realtor.com site sometime in the near future.
-Matt March 15 Hourly HD View at European Ski Resorts
The French company Shaktiware has just launched two camera rigs that automatically generate a 120MP HD View every hour. Francois from Shaktiware tells me that the robot camera scans the scene in about 2 minutes. This is followed by an automatic process that assembles the multiple source images and uploads the result to their servers.
I'm hoping to see more cameras from Shaktiware come online soon. If you're in that part of the world it would be fun to send us a message via the camera. Did anyone see the marriage proposal done on the time lapse camera at the Apple store in Manhattan (see here and here). Seems like you could do something similar with this setup - hold up a different sign at each camera position. -Matt
