"Say cheese!" This simple command is meant to elicit a smile from potential photography subjects no matter what their age. It has become so commonplace that the word "say" is often no longer uttered. A simple "cheese" spreads a smile across anyone's face, and with a click of a button, that smile is captured for eternity.

No one can say for sure who coined the phrase "say cheese" for use in getting people to smile, nor can we say with 100% certainty why that particular phrase was chosen as the smile spreader. The leading theory, however, as to the "why" of "say cheese" is that the "ch" sound causes one to position the teeth just so, and the long "ee" sound parts their lips, forming something close to a smile.

The phrase appears to have been first used in this way around the 1940s, with one of the earliest references appearing in The Big Spring Herald in 1943:

It is thought the "politician" he was referring to was none other than  Franklin D. Roosevelt, who Ambassador Davies served under.  So did President Roosevelt himself come up with the phrase or simply learn it from someone else?  Nobody knows, but soon after, saying cheese became a common phrase for people to utter when trying to get people to smile in photographs.

You wouldn't have had to worry so much about this cheesiness in the Victorian era (1837-1901). During this period, etiquette and beauty standards were much different than they are today. In Victorian times, a small, tightly controlled mouth was considered beautiful. In fact, photographers during this era elicited the desired portrait expression by having their subjects "say prunes". Smiles during this time were only typically captured on children, peasants, and drunks.

One of the most common culprits blamed for the neutral expressions on subjects during the Victorian era is the long exposure time for photographs to be taken. In 1839, Louis Daguerre introduced a new form of photography, Daguerrotype, where a positive of the image was developed directly on the photographic plate. This did not allow for reproduction of shots taken, but it did cut down exposure time significantly. Daguerrotypes remained extremely popular until the 1860s. From 1839 - 1845, exposure time for Daguerrotypes was about 60 - 90 seconds, which was a long time to remain motionless and hold a smile, but not impossible.

By 1845, exposure time on daguerrotypes was cut to only a few seconds. The majority of pictures we see are daguerrotypes taken after 1845, thus eliminating the blame for the lack of pearly whites shown by our ancestors of the Victorian era on long exposure time.

Speaking of pearly whites- the next most common reason cited for people not smiling in photographs in the Victorian era is blamed on dental hygiene. The most common cure for sick teeth during this time was to pull them out. There were no caps or other fixes to make chipped or broken teeth more aesthetically pleasing. So perhaps the reason tightly controlled mouths were considered more beautiful than beaming smiles in the Victorian era was in part due to dental hygiene.

Keep in mind too that daguerrotypes were expensive. The rich were more likely to be photographed than the poor, and even then, most families were only photographed on special occasions, perhaps only even once in a lifetime. The majority of these photographs were taken in a professional photography studio. There was nothing casual about photos taken then and the etiquette for formal occasions at that time was to act "prim and proper". What was socially acceptable in photography during the Victorian era mirrored the beauty and etiquette standards of the times.  You wouldn't want to pay all that money and have the one time you're photographed in your lifetime showing you smiling like a drunkard!

Fast forward to 1888. This is the year George Eastman founded Kodak, a company most widely known for its production of photographic films. Kodak changed the face of photography in more ways than one. Kodak brought photography to the masses and to all occasions ranging from super casual to superbly formal. The company introduced its first pocket camera at a cost of $5 ($135 today), the Pocket Kodak, in 1895. It was the introduction of Kodak's $1 Brownie camera in 1900, however, that changed the world of photography forever.

The Brownie camera was intended to be so inexpensive and so simple to use that anyone could take a picture. In fact, the Kodak slogan at this time was, "You push the button, we do the rest." Photography as a hobby was now a possibility. Capturing "everyday" moments was now a reality- more and more smiles were now captured on film.

So when did it become tradition for people to smile in photographs? This happened in the beginning of the 1900s, due to more and more casual moments being caught on film both in Hollywood and amongst family and friends.
