There’s a new world record holder. The title of “largest photograph in the world” now belongs to the same place that can boast the tallest building in the world. It’s Dubai, home of the 2700-foot-tall Burj Khalifa skyscraper and subject of the 45-gigapixel panoramic cityscape. Equivalent in size to 100 billboards, Gerald Donovan’s photograph is a composite of 4000 images made over four hours. I don’t know that I have the patience to spend four hours creating an image like this, but I could probably easily spend several hours zooming in to examine the details in this image. I never get tired of gigapixel panoramas, and this one doesn’t disappoint. Though it appears a little hazy and not so densely populated as some European gigapans, it’s still worth a good exploration. After all, the haze comes from smog (rather than a poor exposure) and what it lacks in human interest it makes up for in human ambition. With this image, you can really see Dubai’s rapid expansion writ large in amazing detail.
