A photo essay was a series of photographs that aimed to illustrate a topic with images rather than describe it in words. In 2375, The Doctor came down to USS Voyager's engineering section to take pictures for a photo essay entitled "A Day In The Life Of The Warp Core". Annoyed by his hovering, B'Elanna Torres told him to leave three times, finally becoming so frustrated that she destroyed his holographic camera. (VOY: "Juggernaut")
