Description

Panasonic cameras such as the Lumix DMC-GF1 and GF3 produce RW2 files. metadata-extractor parses the TIFF successfully, but the tags are unknown or even incorrectly presented.

Note that Exiftool can process these files.

Research direction
Investigate the RW2 format by studying Exiftool's source code or documentation. Examine sample RW2 files to identify needed tags. In the metadata extractor codebase, look at the existing TIFF processing classes (e.g., TiffReader.java, ExifTiffHandler.java) and consider adding a new PanasonicRawDirectory class to capture RW2 specific tags. Reference the existing Fujifilm or Olympus raw support as implementation patterns.
