The format is designed for Kodak cameras to store uncompressed RAW images in their original form without auto color and white balance correction. The file has a TIFF-structure that allows you to edit the color temperature and exposure of the finished image without losing information and quality, which is something that cannot be done with JPEG format images.
This format has the same color structure as RGB, but it includes an alpha channel that is used to display various levels of transparency. The transparency value is set from 0 to 1, where 1 corresponds to opacity. It is described using the CSS3 programming language.
