BiggestPhoto-Post.JPG

To the photographer's knowledge, this is the largest photograph ever taken indoors. (Well, sort of: It's actually 2,947 different photos all stitched together into one massive, 360-degree experience.) Clocking in at 280,000 x 140,000 pixels, the completed picture, taken by 360cities founder Jeffrey Martin, shows the inside of the Strahov Monastery's library.

TechCrunch has all of the photo's specs from Martin himself: "The photo is 40 gigapixels (40,000 megapixels); 280,000 x 140,000 pixels, made of 2,947 images joined together; used a Canon 550D and 200mm lens; print siz 23m x 11m; stitched file size 280GB; cut into 85,000 tiles for web delivery."
