Feast your eyes upon this image. No it's not just a random cityscape image - it is in fact the World's largest digital photo.
Weighing in at a whopping 272 gigapixels, this image of the Shanghai skyline far outshines the 70 gigapixel beast of Budapest and the recent 90 gigapixel monstrosity of London. To give you an idea of size - your average smartphone or household digital camera snaps around two and 20 megapixels. So how big is a 272 gigapixel image exactly? 1 gigapixel is 1000 megapixels, which is 1 billion pixels. So we're looking at 272 billion pixels, which is large enough to cover 7000 billboards.
The catch to the pic is that it's not just one seamless image - it's a patchwork quilt of 12,000 images stitched together, comprising of 150 columns and 80 rows of images.
Want to have a crack at the title of World's largest digital photo? Alfred Zhao, the photographer, used a Canon 7D with a 400mm f/5.6 lens and 2 teleconverter combined with a GigaPan EPIC Pro robotic camera mount. It took Zhao 1 whole day to shoot all 12,000 images and months to compile and upload the 1.09TB file. Zhao was inspired by earlier record-breaking photos, including the 26 gigapixel image of Dresden, created by German photographer Holger Schulze in December 2009. At the time, it was considered the world’s largest image. One year later, Zhao’s image of Shanghai is more than 10 times that size.
