Check out Prague’s Old Town in this 405 gigapixel photo

Jeffrey Martin takes massive panoramic photographs of the world and his photos let you go from from the panoramic to the intimate in a single mouse swipe. Now he’s truly outdone himself with a 900,000 pixel wide photo of Prague’s Old Town that took six months to build.

The photo, viewable here, has a total spherical resolution of 405 gigapixels and amazing. Martin used a 600mm lens and 50MP DSLR to take photos of nearly everything in the Old Town. You can see the Cathedral, Castle Hill, and even spot street signs, building signs, and pigeons. It’s a fascinating view of a beautiful city.

Martin said it took him over six months to post-process the picture and it required thousands of photos and tweaks. He said the files are six times bigger than anything Photoshop can manage so he found himself working with delicate fixes as he stitched this amazing photo together.
