This tutorial goes over using Aperture to batch process high volumes of greenscreen (or bluescreen) photos. For photographers doing little league, school photos, or events, this is a critical function. We'll use Digital Anarchy's Primatte Event to remove the greenscreen backgrounds and composite in backgrounds. Primatte Event is a plugin that turns Aperture into a real time greenscreen photography solution. It makes use of Aperture's Batch feature beautifully creating a very smooth and easy workflow for this type of work.
