Francis Gregson (active 1898) was a British photographer and war correspondent, attached to the Anglo-Egyptian troops under the command of Herbert Kitchener during the reconquest of the Sudan. Gregson is believed to have been the author of an album of 232 photographs called "Khartoum 1898", taken during the Anglo-Egyptian military campaign in Sudan from 1896 – 98. These photographs in the archives of the National Army Museum, London, have been attributed to Gregson and constitute an important body of photographic records of this British military involvement in the Sudan. They have also been of importance in forming the public's views of 19th century British Imperial warfare.
In the 21st century, these photographs, along with other historic records, including objects taken from Sudan to British museums, have been the subject of critical interpretation of the ethics of British military campaigns in the Sudan. With regard to the changing interpretation of the history of military campaigns, some contemporary historians have argued that war photographers have also contributed to the dehumanisation of the victims.
