I've been working on an automated panorama head for a while (more about that in a later post), and wanted to see how far I could push it. This weekend, the Red Bull Air Race in Rotterdam provided an interesting view, and after a lot of stitching my very first gigapixel panorama was the result.
This image is a 1 gigapixel version of the original 1.8 gigapixel stitch consisting of 400+ images shot with a Nikon 18-200 mm lens on a Fuji S5 Pro. I cropped and scaled the image down because the additional .8 gigapixel did not add all that much to the image experience, yet it added another 300 Mb to the zoomable image.
Those looking closely at the image may find that the image has been doctored. Duh! It's a composite of 400+ individual shots. But the image is more 'doctored' than strictly necessary for the period of time it takes to shoot the photos.
The first reason is that the weather during the Air Race in Rotterdam was lousy. Lighting conditions changed every couple of minutes, and there was an almost constant drizzle.

Secondly, it just made the image more interesting to look at. Spotting a single Red Bull plane is fun, but seeing it do half a lap is more fun. One or two small boats are fun, but adding the Eurodam which started its maiden voyage one and a half week before adds more to look at. And sunbathers are more fun to spot than grass in an empty park.
Most of the gigapixel panorama was shot on juli 14th: 367 shots in about 45 minutes. I had to go back up the Euromast two days later, because my camera 'jammed' a couple of times which meant there were a couple of 'holes' in the panorama. The big ship near the Erasmus bridge, as well as some of the sunbathers were shot on juli 4th, and the pilons, planes and choppers were shot on juli 20th.
The base panorama was shot using the panorama robot I am working on, and stitched using PTGui. Individual shots from the other days were then manually blended in with the base layer in Photoshop, resulting in a layered file of a whopping 7.2 gigabyte. This file takes about 55 minutes to load in Photoshop, but after that most manipulations are surprisingly smooth. The additions from juli 20th were hardest to blend in place, because the weather was dramatically different that day.
The robot, and my gigapixel shooting technique, are still a work in progress. Next time, I hope to get much better focus out of the lens, and a bit more reliability from my robot. Other than that, I considder this experiment a success...
