Remember a decade ago when you were excited about having a 3 megapixel camera? It’s laughable now that you’ve got a 12 megapixel DSLR and someday you’ll have a camera that makes that look like a toy. Heck, someday we could be measuring cameras in gigapixels. Sounds outrageous? Well we’re already measuring photos that way. The current largest indoor photo in the world measures to around 40 gigapixels or 40,000 megapixels. Of course it wasn’t taken with a 40 gigapixel camera—it’s comprised of 3,000 individual photos that have been stitched together to create a single 360 degree image. The subject of the photo is the Stahov Philosophical Library in Prague and the detail is so astounding that you can actually read many of the book covers in the library.
