Primatte Event is a plugin for Aperture that turns Aperture into a real time Greenscreen Photography solution. By using Apertures tethering feature, photos can be captured live, processed in Primatte, and then printed or saved all in a couple of minutes. It's an incredibly powerful way of handling event, school, little league sports or any type of photography that requires a live shooting environment.
