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 Compound Image
JPEG 2000 for multi-layer documents.
JPM (JPEG 2000 Part 6) is a compound image file format. It is designed for storing document images that contain a mix of text and graphics, using a Mixed Raster Content (MRC) model. It allows for different compression methods to be applied to different 'layers' of the image (e.g., sharp edges for text, smooth gradients for photos).
JPM splits an image into multiple layers (e.g., background, foreground mask, foreground color). Each layer can be compressed differently (e.g., JBIG2 for text mask, JPEG 2000 for background photos), optimizing both quality and file size for scanned documents. This is significantly more efficient than compressing an entire scanned page as a single JPEG 2000 image.
Part of the JPEG 2000 standard (ISO/IEC 15444-6), specifically targeting the document archival market.
