Sorry Eiffel Tower, I had to Giga Pixelize you. A gigapixel is 1 billion pixels! or 1000 Mega pixels. To put it in context, most cameras in the market are around 8 Mega pixels.

Eiffel Tower GigaPixelized
How it was made:
The image was constructed with about 230 zoomed-in photographs with overlapping portions . To prevent differences in shade, colour and focusing, the shutter speed, aperture, focus, ISO and White balance were kept fixed in manual mode. After an unsuccessful at stitching in GIMP, the photos were combined using gigapan sticher. Their site shows photos in flash, so easily zoomable.
Although my hotel was 900 meters from the Eiffel tower, I couldn't manage to go up in my 7 day visit. After reaching Paris, I caught a bad flu. The American medicines were no match for the artillery of French bacteria. So in the 7 day period, the only real tourism I did was a 2 hour bus ride. (Resting in bed most of the time). These photos were taken while waiting for the Hop-on-Hop-Off bus.
