There are megapixels and then gigapixels. The latter are the trademark of the "world's largest photograph" which reaches the 353 gigapixels.
How can a photo be so great? From multiple photos together.
The photographer Filippo Blengini, together with five friends, published a panorama of Mont Blanc, the highest mountain in Europe.
They used a Canon 70D, a Canon EF 400mm f / 2.8 II IS, and a Canon Extender 2X III with a special Clauss robotic mount, and drew a total of 70.000 photos from all directions at temperatures ranging from minus 10 Celsius.
Four simple controls allow you to view the photo, but its performance screen may vary depending on the computing power of your computer.
For post-processing of around 46 terabytes it took two months.
