Tom Hogarty has announced Camera Raw 5.2, along with letting us know that Lightroom 2.2 will be along in December.
There’s a list of new cameras supported including the new Canon 5D MkII. Panansonic files that need to be converted to DNG have a little caveat whereby they increase to 3 times the normal raw file size. This is because the 3 channels (red, green and blue) need to be added in linear form, allowing lens corrections from Panasonic to be included in the file. A future version of the DNG spec will change this back to normal size, allowing lens compensations to be stored in metadata in the DNG file.
