The World’s Largest Photo
The World’s Largest Photo – The 2.5 gigapixel photo!
TNO has produced the largest digital panoramic photo in the world. So, what do we mean by large? After all, modern consumer cameras can easily take a picture with 5 million pixels. Hey, I’m talking about a photo of completely different dimensions. One with 2.5 billion pixels - that’s 500 times more pixels. If this photo were printed, it would measure 6.67 m by 2.67 m (300 dpi). The photograph shows Delft and its surroundings in the autumn of 2004. It was taken from the top of the Electrical Engineering faculty of Delft University, at a height of about 100 m, by TNO.
