It’s quite a coincidence, but two of the largest images in the world were both announced recently. These images were created by taking thousands of individual high-resolution photographs and stitching them together to create gigantic panoramas.
Dresden – 26 gigapixels
The first, and the largest image in the world currently in terms of megapixels, is a panorama of Desden, Germany. It boasts a whopping 26 gigapixels:
It was created using 1,665 individual 21.4 Megapixel photographs taken with a Canon 5D Mk II and a 400mm lens. A robot was used to shoot the photographs, and spent 172 minutes capturing the images. The 102 gigabytes of RAW data that resulted took 48GB of memory, 16 processors, and 94 hours to convert.
The photo was taken on the roof of the building “Haus der Presse” and starts at the left side with the Ostragehege. You can see the Congress Center and the Maritim Hotel rightwards. In the center is the city of Dresden with the famous Semperoper (back view), the castle and the Church of Our Lady. In the background is the television tower and you can identify outlines of the Saxon Switzerland. In the right part you can see the south of Dresden.
Prague – 18 gigapixels
This second image has less gigapixels than the previous one, but is a 360-degree panorama, meaning you can look in every direction:
