A gigapixel image is a digital image composed of more than one billion pixels. It contains more than 150 times the detail captured by a typical 6 MegaPixel consumer camera. The high-resolution artwork on this website ranges from 20 MegaPixel to over 2 GigaPixel.
Gigapixel images are created by tiling a large number of photographs, or scanning a large film negative (8" x 10"). Gigapixel images are displayed on-line using streaming technology which breaks the image into small tiles and loads them as you look. This allows you instantly view high-resolution images that are over several gigabytes in size.
Yes, gigapixel images can be printed. At a size of over 20ft (6m), a gigapixel print retains jaw-dropping detail even when viewed a few inches away.
