Our professional photographer sets up our portable Green Screen Studio in one location at your event. The guests' photos are then taken in front our green screen background. Their picture will be complete is less than a minute. In their picture the green screen background will be replaced by a photo of your/their choice. At Billy Buttons Instant Party Pics, we have found that giving the guests background choices at the event often slows down the process. Therefore, we rcommend the host choose the background before the event starts.
