Militairen van de Gordon Highlanders ontvangen een bericht op de heliograaf, Zuid-Afrika 1900

This stereoscopic photograph from 1900 depicts a group of Gordon Highlanders soldiers in South Africa using a heliograph to signal. The heliograph, a device that uses mirrors to reflect sunlight, was a vital form of communication during the Second Boer War. The image captures the stark landscape of the battlefield and the soldiers' determination. The photograph is an example of photojournalism, documenting a specific moment in time, and provides insight into the use of technology during war.
