Ok ... this is gonna blow your mind.
A post on the Fuji Talk Forum by member Fotonut reminded me that there is a site called GIGAPIXEL that displays enormous images ... many gigapixels in size ... that allow one to zoom in to see incredible detail.
The dresden shot is beautiful, and consists of 1,665 21.4mp images from a Canon 5D Mark II. It was recorded by a photo robot over 172 minutes and required 64 processors and 48GB RAM to process the 102GB of RAW imagery over 94 hours.
The final image has a resolution of 297,500 x 87,500 pixels, or 26GP ... that's pretty huge. If printed at a nominal 100 pixels per inch, i.e. billboard resolutions (and equivalent to your monitor resolution fully zoomed in) the image would be ... wait for it ... 247 feet wide :-)
I shit you not.
Here is a tiny version of the image that represents what you would see here ... click on it to see a bit more detail or click on that link to see the actual site ...
On the left side there is a bridge. A long bridge with several lanes ... in fact a couple of bridges if you zoom in. And if you zoom in all the way to the middle of the bridge, you will see a couple of guys working there ... and you will be astounded at how close you can get ...
Amazing stuff, GIGAPIXEL ... have a look.
