Panasonic Lumix RAW
The raw format for Lumix G and S series cameras.
RW2 is the proprietary raw image format used by Panasonic Lumix cameras, ranging from the Micro Four Thirds G-series (GH5, G9) to the full-frame S-series (S1, S5). RW2 files contain the raw sensor data. Like Olympus ORF files, they rely heavily on embedded lens correction profiles to correct the distortion and vignetting inherent in compact lens designs.
RW2 files are TIFF-based containers storing 12-bit or 14-bit sensor data. They include a large JPEG preview and extensive metadata describing the lens characteristics.
Replaced the older .RAW extension used by very early Panasonic cameras. It has been the standard for over a decade.
Pyramid TIFF
A multi-resolution TIFF optimized for deep zooming.
PTIF (Pyramid TIFF or Pyramidal TIFF) is a standard TIFF file that has been structured to contain multiple resolution levels of the same image (a 'pyramid'). This allows software to open immense images (e.g., gigapixel maps or medical scans) almost instantly by loading only the low-resolution tile suitable for the current zoom level, rather than decoding the entire massive file.
Inside the TIFF wrapper, the image is stored as a series of SubIFDs (Image File Directories). The main image is typically the highest resolution. Subsequent directories contain the image downscaled by powers of two (50%, 25%, 12.5%, etc.). Additionally, the image data is usually 'tiled' (broken into usually 256x256 blocks) rather than 'stripped'. This enables random access to specific regions.
