There are always several opportunities to take a group photo every year, and each time it is a torment. A photo crowded dozens of faces, leaving a brilliant image for everyone, which is really a test for photographers. People who take pictures have bad taste, too. You have to be highly consistent with others and try to keep your eyes open without blinking. But the more you can't blink, the healthier your eyes are. Therefore, when the photographer presses the shutter, someone blinks unwillingly and becomes blind. However, the hardest thing is to grin. It's easy to laugh; It's hard to show the standard eight teeth and smile vividly. The photographer tried to find some ways. The earliest photographers liked to shout "one two three". Deliberately dragging a long cavity, in fact, he had already pressed the shutter when he called "two". The problem of blinking has been solved, but the faces of the people in the photos are all tight muscles and look very bitter. We must make everyone laugh. A smile is the most vivid image of a person. Some people just can't laugh. I don't know which photographer was the first, so I came up with a clever way to make everyone shout "eggplant" in unison. With the sound of "eggplant", everyone's muscles relaxed. Moreover, the louder the voice, the more accurate the pronunciation of Mandarin, and the brighter the smile. Eggplant is like a flower, blooming on people's faces. It is often seen that a row of people and another row of people stand together layer by layer, and under the slogan of the photographer, they give out loud "eggplant" in unison.
