Gigapixel Image Capture - Diamond Jubilee Portrait


For the official Diamond Jubilee Portrait of the Queen, the British based Australian artist Ralph Heimans created a large scale and life-sized painting. MAX was commissioned to create a Gigapixel image of the painting at a resolution that would reveal every intricate brushstroke.

To create a digital copy of the painting we used a Hasselblad camera fitted with a Phase One camera back. However, even the most sophisticated medium format digital cameras are not capable of revealing all of the detail of such a large-scale work. We therefore shot twenty-eight individual pictures of sections of the painting, which we merged into one seamless image of over 1.5 GB in file size using the latest imaging technologies. To generate a prefect image we had to ensure that the lighting was consistent and that there was no glare from the highly glossy surface of the delicate oil painting.
