A carte-de-viste is a type of portraiture in which the final print is about the size of a greeting card, hence its name. It follows the basic fundamentals of a wet plate negative and a single print could be replicated up to eight times. It is essentially a photo booth in which the subject has several poses. It became common for celebrities of the day to take this easy style portraits, have them replicated and sold, so as to turn a profit. Basically it is the beginning of the celebrity poster craze.
