If you open up address book, select a contact, click edit and double click on the photo area of a contact, it will bring up a window, where you can either choose a image on your computer, or take one with your webcam, there is a button to take a picture, and a button to change the camera effect, but there are 6 pages of effects, where photo booth only has 2 excluding the backdrop effects. They have ones like ASCII, Blue Print, City Lights, Color Invert, Concert, Dot Screen, False Color, Film Stock, Kaleidescope, Neon, Line Overlay, Tracer, Posterize, and many more that aren't in Photo Booth. WHY!??? You can even put in any photo of the contact you want, and then double click on it, and choose one of these effects, and it will apply it to the picture. But I just don't understand why Apple doesn't have these in Photo Booth, there are some really awesome effects in Address Book. Does anybody know how to get them to Photo Booth?
