Alfred Stieglitz HonFRPS (/ˈstiːɡlɪts/; January 1, 1864 – July 13, 1946) was an American photographer and modern art promoter who was instrumental over his 50-year career in making photography an accepted art form. In addition to his photography, Stieglitz was known for the New York art galleries that he ran in the early part of the 20th century, where he introduced many avant-garde European artists to the U.S. He was married to painter Georgia O'Keeffe.

Edwin Herbert Land, ForMemRS, FRPS, Hon.MRI (May 7, 1909 – March 1, 1991) was an American scientist and inventor, best known as the co-founder of the Polaroid Corporation. He invented inexpensive filters for polarizing light, a practical system of in-camera instant photography, and the retinex theory of color vision, among other things. His Polaroid instant camera went on sale in late 1948 and made it possible for a picture to be taken and developed in 60 seconds or less.

Steve McCurry (born April 23, 1950) is an American photographer, freelancer, and photojournalist.

Yousuf Karsh CC RCA FRPS (December 23, 1908 – July 13, 2002) was an Armenian-Canadian photographer known for his portraits of notable individuals. He has been described as one of the greatest portrait photographers of the 20th century.

An Armenian genocide survivor, Karsh emigrated to Canada as a refugee. By the 1930s he established himself as a significant photographer in Ottawa, where he lived most of his adult life, though he traveled extensively for work. His iconic 1941 photograph of Winston Churchill was a breakthrough point in his career, through which he took numerous photos of known political leaders, men and women of arts and sciences. More than 20 photos by Karsh appeared on the cover of Life magazine, until he retired in 1993.

He received the Royal Photographic Society Progress Medal, alongside his colleagues Professor Joachim Frank and Dr Richard Henderson, in 2018 for 'an important advance in the scientific or technological development of photography or imaging in the widest sense'.
