The photo sticker booth phenomenon started in Japan in the mid-90s and is known there as "Purikura." It didn't take long for them to become popular throughout Korea. Nowadays, these booths are found everywhere from amusement parks to malls to arcades. There are even sticker booth shops.
Perhaps it's a personal opinion but I think the "big eye" editing feature is wayyyy creepy. (Photo Credit: JapanTrends)
After taking the photos (about 6 or so shots), users must then rush to the rear part of the machine to edit/design their photos. Time is limited so everyone must act fast. Designs can include small pictures to pretty boarders to sparkly text. Users can then select how many pictures they want to pick out; the more pictures printed, the smaller they are. After printing, the photos can be brought to the store attendant who will put a matte or shiny coating on the photos, depending on the patrons' preferences. You can pay a little extra to get fun accessories, like a cell phone charm to place your picture in.
