Kodak DC25 RAW
A relic from the dawn of digital photography.
K25 is the raw format used by the Kodak DC25, a camera released in 1996. It is one of the earliest examples of a consumer digital camera raw format. The camera had a resolution of less than 0.2 megapixels.
K25 files are simple dumps of the CCD sensor data. They are extremely small but require specific decoders to be read today.
Kodak was a pioneer in digital imaging, and the DC25 was a significant early model.
JPEG 2000 Code Stream
Another extension for the raw JPEG 2000 code stream.
J2K is functionality identical to J2C. It represents a raw JPEG 2000 codestream without the JP2 file format wrapper. It is often used interchangeably with J2C and JPC in technical contexts.
Like J2C, a J2K file contains the wavelet-compressed image data (SOP/EPH markers). It relies on the decoder to interpret the stream markers correctly without the 'boxes' found in the JP2 container format.
Part of the ISO/IEC 15444-1 standard. The multiple extensions (.j2k, .j2c, .jpc) arose from different vendor implementations early in the standard's life.
