PictureCode has released Noise Ninja as a plug-in for Aperture. The powerful noise reduction software has the core capabilities of the Photoshop version, but has a more simplified user interface that meshes with the Aperture system. The Noise Ninja plug-in also supports the multi-file handling method that Aperture’s framwork makes possible.
The Aperture version of Noise Ninja is somewhat stripped down, compared to the standalone version: it has no preference dialog, for instance. But the capabilities of this plug-in remain the same.
It is available as part of the PictureCode Pro Bundle.
