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.
The picture was made with the Canon 5D mark II and a 400mm-lens. It consists of 1.665 full format pictures with 21.4 megapixel, which was recorded by a photo-robot in 172 minutes. The converting of 102 GB raw data by a computer with a main memory cache of 48 GB and 16 processors took 94 hours. With a resolution of 297.500 x 87.500 pixel (26 gigapixel) the picture is the largest in the world. (stand December 2009)
