Kodak RAW
A relic from the pioneer of digital photography.
DCR is a raw image format used by older Kodak Professional digital cameras (like the DCS Pro SLR series). Kodak was a pioneer in digital imaging, and their DCS cameras were often built on Nikon or Canon bodies but used Kodak sensors and processing. DCR files contain the raw data from these CCD sensors, which were famous for their color rendition but infamous for their noise at high ISOs.
DCR files are TIFF-based but use proprietary tags and compression. They store uncompressed or losslessly compressed sensor data. Kodak had several raw extensions (.dcr, .k25, .kdc), reflecting the chaotic early days of digital standards.
Used primarily in the late 90s and early 2000s. Kodak exited the high-end professional camera market in 2005, making this format effectively dead.
JPEG 2000 File Format
The advanced successor to JPEG that never quite took off on the web.
JPEG 2000 (JP2) is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard with a newly designed, wavelet-based method.
JP2 uses discrete wavelet transform (DWT) technology, which allows for higher compression ratios without the 'blocky' artifacts seen in standard JPEGs. It supports both lossy and lossless compression in a single architecture and allows for progressive decoding (quality or resolution).
Released in 2000 as a modern upgrade to JPEG. Despite its technical superiority, it failed to gain widespread web adoption due to patent concerns, complexity, and the 'good enough' nature of standard JPEG.
