How I Made a 1,474-Megapixel Photo During President Obama's Inaugural Address by NYC photographer David Bergman.

I made a panoramic image showing the nearly two million people who watched President Obama's inaugural address. To do so, I clamped a Gigapan Imager to the railing on the north media platform about six feet from my photo position. The Gigapan is a robotic camera mount that allows me to take multiple images and stitch them together, creating a massive image file.

My final photo is made up of 220 Canon G10 images and the file is 59,783 X 24,658 pixels or 1,474 megapixels. It took more than six and a half hours for the Gigapan software to put together all of the images on my Macbook Pro and the completed TIF file is almost 2 gigabytes.

Use the controls to zoom and pan around the photo. You can also double click to zoom in and double click again to get even closer.

Here's a direct link to the full-screen photo from which to start zooming.

How good is it?

In this screenshot made after I zoomed into the crowd are 4 former presidents, 5 first ladies, 2 vice presidents and Aretha Franklin -- a once in a lifetime moment. See it double this size by clicking on it.

At the moment this photo was taken, Obama was giving his speech from the jutting semicircular balcony by the bottom bunting.
