A photo booth is a vening machine or modern kiosk that contains an automated, usually coin-operated, camera and film processor. Today the vast majority of photo booths are digital. Traditionally photo booths contain a seat or bench designed to seat the one or two patrons being photographed. Once the payment is made, the photo booth will take a series of photographs (though most modern booths may only take a single photograph and print out a series of identical pictures). Before each photograph, there will be an indication, such as a light or a buzzer, that will signal the patron to prepare their pose. After the last photograph in the series (typically between 3 and 8) has been taken, the photo booth begins developing the film, which whilst it used to take several minutes in the old 'wet chemistry' booths, now with digital technology will take typically about 30 seconds and then deliver the strip of prints.
