Camera RAW 5.2 is Out

Camera Raw 5.2 is out and it supports the following cameras but only for Adobe CS4.  For Lightroom users, have to wait until version 2.2 release in December, bummer.

Important note for Panasonic and Leica D-LUX4 users, according to the Adobe website,

“With the release of Camera Raw 5.2 (and upcoming Lightroom 2.2 release) 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. For those choosing to convert these native, proprietary files to the DNG file format, a linear DNG format is the only conversion option available at this time. 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.”
