Convert RW2 to PHM

The RW2 file extension stands for Panasonic Digital Camera Raw Image File, primarily used by Panasonic LUMIX cameras. This format captures uncompressed image data directly from the camera's sensor, ensuring high-quality images suitable for professional editing. Introduced with models like the LUMIX LX3 and LX5, RW2 files are based on the TIFF specification and are similar to other raw formats like RAW and RWL. These files can be opened and edited using various software.

The PHM file extension stands for Portable Float-map Image (16-bit half), a format used for storing High Dynamic Range (HDR) images with 16-bit half-precision floating-point values. This format is particularly useful in applications requiring precise color representation and extensive dynamic range, such as computer graphics, image processing, and scientific visualization. Originating from the Portable FloatMap (PFM) format, PHM was developed to provide a more efficient storage solution by utilizing half-precision floats, thereby reducing file size while maintaining significant detail and accuracy.
