cf/x cookie cutter is like an ordinary cookie cutter; which as everyone knows, is a piece of metal or plastic, bent into an easily recognizable shape (heart, moon, angel, flower etc.). The shape is pressed into fresh cookie dough in order to quickly cut out the shape. The cut out shape is then transferred to the oven and baked into a cookie.
cf/x uses the same metaphor to quickly cut out a shape from any photo. In cf/x cookie cutter, all you do is select the shape, place it on your photo, and - boom - you have a perfectly cut out from your photo.
