Kodak DC Series RAW
A raw format from the early consumer digital era.
KDC is a raw image format used by Kodak's consumer digital cameras (DC series) in the late 90s and early 2000s, such as the DC40, DC50, and DC120. Unlike the professional DCR format, KDC was aimed at the mass market.
KDC files are TIFF-based but use a specific compression and encryption scheme that made them difficult to open in third-party software for years. They contain raw sensor data, allowing for post-processing flexibility unavailable in standard JPEGs of that era.
Kodak was trying to bring better quality to consumer cameras. The format disappeared as Kodak shifted focus and eventually left the camera market.
BigTIFF
TIFF for files larger than 4GB.
BigTIFF (often referred to as TIFF64) is an extension of the classic TIFF format designed to break the 4GB file size barrier. It uses 64-bit offsets instead of 32-bit, allowing for files up to 18,000 petabytes.
Standard TIFF uses 32-bit integers for file offsets, limiting the file size to 2^32 bytes (4GB). BigTIFF changes the internal structure to use 64-bit integers. It is not backward compatible with older TIFF readers that only understand 32-bit offsets.
Developed to address the needs of geospatial and medical imaging, where single images often exceed 4GB. It is supported by LibTIFF starting from version 4.0.
