Gorffennol Digidol 2016: Gigapixel Photography
A Gigapixel image is one comprising of billions of pixels, enabling you to view detail without the degradation you would see in a normal photograph. Current technology for creating such high-resolution images involves stitching together and rendering a mosaic of digital photographs to create one image – the world’s largest photo to date, that of Mont Blanc, was shot in 2015 and comprises of 70,0000 images and 365 billion pixels, if printed the photo would be 98 metres long and 23 metres high.
The use of Gigapixel photography in heritage is growing and can be undertaken using a standard digital camera and workstation. High-resolution images can be created for landscapes and individual sites as well as documents (e.g. manuscripts and maps). There is also great potential in using these images to create interactive virtual tours.
