| City Lights, San Francisco at Dusk This is a 1.1 gigapixel (13,423h x 80,540w, 1x6 ratio) view of San Francisco reduced to 10% of its original width and height. It was created from 112, 11-second exposures with the 21 megapixel Canon 5D MKII, a Canon 500L lens with a 1.4 extender. The photos were taken just after sunset from the Marin Headlands on several different evenings under similar lighting conditions. It took over 20 return trips over a two month period to witness those evenings with similar light. All of this effort was required to produce an image that would appear to be taken during that 10-minute period that happens about 20 minutes after sunset when the fading daylight and the city lights reach equilibrium. This could easily be printed at 36ft wide by 6 ft tall (200dpi) with fine resolution with little to no pixelation or noise visible at a viewing distange of 1 foot! I used AutoPano stitching software at first, however it (and other stitchers) became hopelessly confused by the numerous bridge cables since one looks like another. So most of this image was hand stitched by me in Photoshop. Also, I did not use a Gigapan machine or a tripod, I used a plastic bucket, a x-large pizza-sized plywood round and some wood shims. This was far more stable than a tripod in the wind with a huge lens, and easier to level and pan across. Please contact me, Patrick Smith, at patrick @ patricksmithphotography.com with any questions. The 2.5 gigabyte 8-bit psb file is for sale starting at US $4,995.00 for the 36 foot version with lower prices for smaller files. There are places that will print files of this size! Also, I have created a gallery on SmugMug where you can buy this as a series of four affordable 2x3 ratio metal prints that you can hang side by side to create a full 2x12 foot panorama effect in your own house at 300DPI! |

| Portions of this panorama The following images are cropped portions left at 100% size. In other words, this is what the photo looks like pixel by pixel. So on your monitor, this is what a print would look like at about 72DPI (or over 100 feet across.) Of course, a 30 foot print will have much finer resolution! |
