Samsung RAW
The raw format for Samsung's defunct NX camera line.
SRW is the proprietary raw format used by Samsung's NX series of mirrorless cameras (like the NX1 and NX500). Although Samsung exited the camera market, the NX1 remains a cult classic for its high-resolution sensor, and SRW files are still relevant for its users.
SRW files are TIFF-based containers holding the raw sensor data. The NX1's SRW files are particularly notable for containing data from a 28MP BSI-APS-C sensor, which was ahead of its time.
Introduced with the Samsung GX series (rebadged Pentax) and evolved with the NX series.
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.
