Apple has released the final version of the SDK for Aperture, its professional photo workflow program. The SDK allows developers to create a variety of custom plug-ins for Aperture 2.1, which introduced an open architecture and came with Apple's own Dodge & Burn plug-in. Already available are a handful of third-party plug-ins; among these are Tiffen's Dfx Digital Filter Suite, which simulates a variety of optical filter effects.
Digital Film Tools, meanwhile, has released three separate ones, including Power Stroke, Light! and Ozone; websites for all of these were inactive at press time. Apple is however promising more third-party add-ons "soon," including dvGarage's dpMatte and HDRtoner, Image Trends' Fisheye-Hemi, and PictureCode's Noise Ninja.
