The diagram illustrates the process by which an automatic photo booth functions to capture and deliver photographs, commonly used for personal or official purposes such as passport applications.
Looking at the illustration, it is immediately evident that this is a man-made, fully automated linear process that involves no human intervention once the user initiates it. The entire procedure consists of several stages, beginning with the insertion of coins and selection of photo preferences, and culminating in the delivery of the final printed images.
In the first stage, coins are inserted into the machine to activate the system. Following this, the user selects between one large-format photograph or four passport-sized images, and also chooses whether the photo should be in colour or black and white—although passport images must be in colour. Then, the individual enters the booth, adjusts the height of the stool to ensure their face is at eye level with the mirror, and closes the curtain completely to block external light.
At the next stage, the user waits for a light signal which flashes after a three-second delay, indicating that the photo is about to be taken. Once this has occurred, the machine processes the image automatically. Having been printed, the photograph is then ready for collection. The process ends when the completed photo is delivered through the output slot within 60 seconds of capture.
Overall, the photo booth offers a quick, convenient and entirely self-operated method of producing official-quality photographs, requiring minimal user input and no external assistance.
