All users have to do is take a picture, hashtag with #EZFLTR, and the FLTR does the rest. 'Lol wuts the rest?", you ask. I can't tell you, because it's a proprietary process that is so complicated it's simple. It basically involves at least two instagram accounts, screenshots, projectors, a fresnell lens, a darkroom, six cups of coffee, ninja skills, and photoshop and/or MSpaint. It's almost #2EZ.
