Adobe Photoshop Lightroom 2.2

The Adobe® Photoshop® Lightroom® 2.2 update includes these enhancements:

• Additional camera support for the Canon EOS 5D Mark II, Canon PowerShot G10, Panasonic DMC-LX3 and more**
• Includes several corrections for issues introduced by the Lightroom 2.0 release

See the Lightroom 2.2 ReadMe file for additional details.

**With the release of Lightroom 2.2, there is an important exception in our 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 only be converted 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 into three distinct layers , one for each channel. The resulting linear DNG file is approximately 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 in Lightroon 2.2 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 only converting these files to DNG to allow compatibility with third party raw converters, previous versions of the Camera Raw plug-in or previous versions of Lightroom.
