A photo booth is a vending machine that takes instant photos. After you pay, usually in coins, a computer-based screen and often a recorded voice will tell you when the picture will be taken, how many shots will be taken and when the photo is developed.
There are many types of photo booths today that offer different sizes and kinds of photos such as passport photos and photos for identification. Also, some photo booths give you a number of tools you can use to create different features for your photos. Sticker photos are a good example. Sticker photos are instant photos printed on sticker-based material. After you take your picture, you can change backgrounds the tone or the color of the photo and insert letters and symbols. Invented in Japan, photo sticker booths are especially popular in Asian countries among teens and grown-ups alike.
