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 (Graphics Interchange Format)
The internet's original animation format, beloved for memes and simple looping graphics.
GIF (Graphics Interchange Format) is one of the oldest and most recognizable image formats on the web. Introduced by CompuServe in 1987, it became the standard for color images in the early internet era. While technically surpassed by modern formats, GIF remains culturally vital due to its unique ability to play short, looping animations without user interaction or player controls. Technically, GIF is an 8-bit format that uses a palette of up to 256 colors from the RGB color space. It employs LZW compression, which is lossless for images with large areas of uniform color. Its most famous feature, animation, was added in the 89a specification, allowing multiple frames to be stored in a single file with timing delays. Despite its limitations—specifically the 256-color cap and binary transparency—GIF's universal support and 'it just works' nature have kept it relevant for decades, evolving from "Under Construction" signs to the primary language of reaction memes on social media.
GIF uses Lempel-Ziv-Welch (LZW) compression, a lossless algorithm that builds a dictionary of data patterns. This makes it extremely efficient for images with flat colors and repetitive patterns, like logos or pixel art, but less efficient for photographs. The format is stream-oriented, allowing for sequential decoding. A GIF file consists of a header, a logical screen descriptor, a global color table (palette), and a sequence of image data blocks. Each frame in an animation can have its own local color table, allowing the animation as a whole to use more than 256 colors, though each individual frame is still limited. Transparency is binary: one index in the palette can be defined as transparent, meaning pixels of that color allow the background to show through fully. There is no partial transparency (alpha channel).
GIF was developed by a team at CompuServe led by Steve Wilhite and released on June 15, 1987. It was designed to provide a color image format for their file downloading areas that would be compressed and exchangeable across different computer platforms. The original specification was '87a'. In 1989, CompuServe released the '89a' specification, which added support for transparent backgrounds, animation delays, and text metadata. This version enabled the animated GIFs that would come to define the early web. The format faced a major controversy in 1994 when Unisys, the patent holder of the LZW compression algorithm, attempted to charge licensing fees. This 'GIF Tax' spurred the development of the patent-free PNG format. The patents eventually expired worldwide by 2004, returning GIF to the public domain.
