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.
Microsoft Icon
The standard format for icons on Microsoft Windows and the web (favicons).
The ICO format is a container for one or more images at multiple sizes and color depths. It allows a single file to store appropriate icons for different display contexts (e.g., 16x16 for menus, 256x256 for desktop). It supports transparency and, in modern versions, PNG compression.
ICO files contain a header followed by an icon directory that lists each image entry. Each entry can use either BMP (uncompressed) or PNG compression. The format supports 1, 4, 8, 16, 24, and 32-bit color depths with optional alpha channels.
Introduced with Microsoft Windows 1.0. It became the standard for website favicons with the release of Internet Explorer 5.
