Kodak Cineon Bitmap Image (.cin)
The CIN file extension stands for Kodak Cineon Bitmap Image, a format developed by Kodak in 1992 to digitize film images for electronic compositing, manipulation, and enhancement. It stores a single frame from a motion picture or video data stream with 10-bit color depth per RGB channel. Although the Cineon System is now discontinued, the format is still used in visual effects and film restoration. CIN files can be opened and converted using applications like Adobe Photoshop and XnViewMP.
