Panorama in 1.3 Giga pixels
View full here (Zoomify) and here (better in my opinion) in Gigapan (you can take screenshots of peculiar places you see). The full-size image is 64156x20210, 229MB when stored as JPEG with little quality loss, 2.8GB when saved as compressed TIFF.
180 pictures at 200mm, 16 at 70mm (for the sky, using a technique I learned from gadl) with a Nodal Ninja 5L on top of a Manfrotto 055PROB, shooting every 2.5° horizontally and every 5° vertically. Control points generated with autopano-sift-c, stitched with hugin (which generated a set of 196 images for a total of 6.7GB), blended with enblend, and edited with Gimp. I needed to compile a patched version of the TIFF library to be able to open the TIFF image (2.8GB compressed). Enblend took 72 minutes of processor time, but with the disk swapping it took more than 13 hours: peak memory consumption was routinely over 12GB with enblend (note to self: next time do not use the maximum number of levels for this). Working with Gimp was quite excruciating, opening the file took at least 8 hours, and required over 12GB of memory. In all, my computer (the new updated one with 4GB RAM) was useless for four days.
See my attempt last year of the same view but not the same location - only 148 million pixels...
