An expression you constantly make out of habit when a picture is being taken. If you have a consistent camera face all your pictures have the exact same expression in them. Usually not a natural smile.
For girls it is usually a fish-face, pursed lip, Victoria Beckham-like pout or a seductive, "I'
m-
hot-and-I-know-it" toothless smile(more often than not to hide braces). For guys it is usually a tough
guy, serious face with a slight upwards tilt of the
head in a "
hey-how-you-doin " kind of way.
