This photograph is a panoramic view of the San Francisco Bay, including the Golden Gate Bridge, San Francisco skyline, and Alcatraz. The Golden Gate Bridge spans the waterway connecting the San Francisco Bay to the Pacific Ocean.
This photograph is approximately 222 megapixels in size, meaning that it can be printed quite large. An image below zooms into a few areas within the full size image, allowing the viewer to see the details available when the photo is printed at full size (see available sizes below). Because the photo is so large, it can be printed up to 90 inches (7.5 feet) wide, making it suitable for decorating larger spaces.
