|(file format, graphics)||Tagged Image File Format - (TIFF) A file format used for
still-image bitmaps, stored in tagged fields. Application programs can use the tags to accept or ignore fields,
depending on their capabilities.|
While TIFF was designed to be extensible, it lacked a core of useful functionality, so that most useful functions (e.g. lossless 24-bit colour) requires nonstandard, often redundant, extensions. The incompatibility of extensions has led some to expand "TIFF" as "Thousands of Incompatible File Formats".
