Taken as part of the GlacierWorks project to document changes to the Himalayan glaciers, this image of Mount Everest has a resolution of 3.8 billion pixels. (Although, admittedly, the print margins of CES do not do it full justice.) It has been produced through gigapixel technology, where a single, super high-resolution image is created from a series of smaller photographs shot in sequence. A team of photographers captures each image, which must overlap the next by a specific amount. Software is then used to recognise the inter-frame overlap and then positions the individual images accordingly.
