From the developer:
TiltShift is an Aperture Edit Plug-In for computer generated tilt-shift photography. The software allows you to create fake miniature versions of regular photos, simulating the effect of expensive tilt-shift lenses.
You can define an arbitrary position for the virtual focal plane and setup its properties using an intuitive visual interface.
