Dynapik offers a free online tool to change image types - no need to download anything. It's quick and easy to use. You can change your TIFF64 images to CIN format. This tool works for both professionals and casual users. Convert your images to CIN in seconds.
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.
Kodak Cineon
A pioneering 10-bit logarithmic format designed by Kodak for digital film scanning and mastering.
The Cineon format (.cin) was developed by Kodak in the early 1990s as part of their Cineon Digital Film System. It was designed to capture the full dynamic range of film negatives. Unlike standard linear image formats, Cineon stores data in a 10-bit logarithmic density format, which closely mimics the response of film to light. This allows it to preserve highlight and shadow details that would be lost in linear 8-bit formats.
Cineon files use 10 bits per color channel (Red, Green, Blue), packed into 32-bit words (with 2 bits of padding). The key feature is the logarithmic encoding: pixel values represent printing density rather than linear brightness. A value of roughly 95 represents 'D-min' (clear film base), and the values scale up to represent increasing density. This allows the format to store a dynamic range that exceeds standard video formats.
Introduced in 1993, the Cineon system was the first end-to-end 4K digital intermediate workflow for motion pictures. While the hardware system was discontinued in 1997, the file format became the industry standard for visual effects and digital mastering until it was eventually superseded by the more flexible DPX (Digital Picture Exchange) format, which is directly based on Cineon.
