2"). prints cost 75p a pair. set up a tab before the event with the option to increase it if you wish. we would advise you to allow one print per guest based on an average of three people per photo and three visits per person to the booth. guests can either keep their photo, stick it in a guest book with a personal message or both! for example, 100 guests will usually fill a medium sized guest book and the photo printing will typically cost around £75 (approximately 200 strips).
