Tilt Shift

Now this will tickle your brain. Tilt shift is what we like to call "miniature faking." This effect can be done with a special lens, but I faked it with Photoshop since I don't have that lens. It's easiest if any people in the picture are tiny, because it is super hard to make people look like plastic figurines if they're large and detailed. I included the originals for some perspective. If you are really having trouble determining which ones are tilt shifted, you should probably get your eyes checked.
