Attached Link: Gigapixel Dresden

The largest gigapixel photograph ever created with a DSLR camera was made by A.F.B. Media GmbH in Dresden, Germany. 1655 images, each 21.6 megapixels in size, were taken with a Canon 5D Mark II and a 400 mm lens over a period of 176 minutes. The images were stitched on a 16 processor system with 48GB of main memory, taking 94 hours to create the final result.

Unbelievable :-)

How very wrong to describe it as they did. It is not a 26 gigapixel photo, it is a 26 gigapixel collage which is quite a different thing. Sorry, no "Gee whiz!" from me!

At the church I attend we once had a huge image of the Bristol, Tennessee, USA race track across  the front of the church auditorium.  This was part of a summer kids event.   The image consisted of many hundreds of images, shot, printed on paper and "stitched" by hand into the final view.  It was very impressive...it was a collage.

The huge image of this link is impressive but it is also a collage.  Still, the feat is surprising in that it was taken on and accomplished.  

Sorry to say I could not effectively utalize the file size on my monitor !  :  )     Considering the number of photos used, the consistency and stitching are impressive.
