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.
GIF 87a
The original 1987 specification of the Graphics Interchange Format.
GIF 87a is the original version of the GIF format, published by CompuServe in 1987. It introduced the core features that made GIF famous: LZW compression for small file sizes and support for 256 indexed colors. However, unlike the ubiquitous GIF 89a, this original version lacks support for transparency, animation delays, and metadata comments.
A GIF 87a file starts with the header signature `GIF87a`. It defines the Logical Screen Descriptor and the Global Color Table. While it supports multiple image blocks within a single file (which could conceptually form an animation), it lacks the 'Graphic Control Extension' block introduced in 89a. This means there is no standard way to define frame delays, disposal methods, or transparent indices.
Developed by CompuServe in 1987 to provide a hardware-independent, compressed color image format for their online service. It replaced the earlier RLE-based formats and was designed to be efficient over slow modems.
