Buena Software Releases Au NaturelPlugin includes tools for lens blurs, adjusting exposure, and compositing (July 28, 2004)
Buena Software, Inc. president Darrin Cardani explains how Au Naturel works: "When you film a scene, then convert it to a digital format and bring it into your host application, the data has gone through many different transformations. Between the electronics in the camera, the conversion to digital data, and the compression applied to it, the data your editing or compositing application receives is no longer representative of what really happened in the scene you filmed. Au Naturel strips away the transformations that were added to your footage and allows you to work in linear RGB, which more closely mimics how light works in the real world."
Au Naturel works in a 32-bit per channel floating point linear RGB color space, giving it a realism not found in other plugins. Blurs produced with Au Naturel cause the same type of blooming in bright areas that defocusing your camera's lens does. Motion blur produced with Au Naturel's directional blur looks more realistic than the host application's built-in tools, too.
In addition to reproducing real blurs, the plugin also includes an extremely high quality transformation tool that allows users to scale, rotate, skew, and translate their footage with sub-pixel accuracy. This produces much higher quality results than the transform or motion tools built into most host applications. And unlike other plugins that only improve the scaling, Au Naturel lets you perform transformations that include rotating, skewing, and translating, too, giving you the most freedom with the highest quality.
But it doesn't stop there! You also get the ability to perform composites in linear RGB. Since linear RGB mimics how light interacts in the real world, this gives you results that are far superior to compositing with other tools. And you can even choose to have a separate alpha channel for each color channel, allowing you to create even more realistic results.
