Everything big is Dubai. They boast the world’s tallest building, the world’s largest shopping mall, and now the world’s largest photograph. Gerald Donovan recently created the 45-gigapixel panorama of the Dubai skyline as a technical test to explore the limits of hardware and software. At the end of last year, the largest photo in the world was a 26 gigapixel shot of Dresden, Germany.

Robotic panorama devices are making the creation of gigantic photographs easier and easier. Donovan used a Gigapan EPIC Pro to create his image, along with a Canon 7D and 100-400mm f/4.5-5.6 L at 400mm. After 3.5 hours of shooting, he had 4,250 JPG images that took up 27.5 GB of his 32GB memory card. If the photograph were to be printed, it would result in a print the size of nearly 1,200 billboards.

Here’s a behind-the-scenes video showing how the photograph was made:
