Additional notes

Note: Beginning with the release of Lightroom 2.2, there is an important exception in the DNG file handling for the Panasonic DMC LX3, Panasonic DMC FX150, Panasonic DMC FZ28, Panasonic DMC-G1, and Leica D-LUX 4. In this release the native, proprietary files from these cameras can be converted only to linear DNG files. A linear DNG file has gone through a demosaic process that converts a single mosaic layer of red, green, and blue channel information to three distinct layers, one for each channel. The resulting linear DNG file is about three times the size of a mosaic DNG file or the original proprietary file format.

This exception is a temporary solution to ensure that Panasonic and Leica's intended image rendering from their proprietary raw file format is applied to an image when converted DNG files are viewed in third-party software titles. The same image rendering process is applied automatically in Camera Raw 5.2 and 5.3 and in Lightroon 2.2 and 2.3 when viewing the original proprietary raw file format.

In a future release, Adobe plans to update the DNG specification to include an option to embed metadata-based representations of the lens compensations in the DNG file, allowing a mosaic DNG conversion. In the interim, Adobe recommends converting these files to DNG only to allow compatibility with third-party raw converters, previous versions of the Camera Raw plug-in, or previous versions of Lightroom.
