[Format] .tif / .tiff [Properties/Technologies] Uncompressed Baseline TIFF v.6 [Description] A de facto standard and widely used in an uncompressed form for storing archival versions of images. The TIFF format is flexible and can supports a number of options such as LZW[2] compression, multiple pages and metadata embedding and data creators should be clear on what type they are producing. The TIFF format supports embedding of EXIF metadata as well as GeoTIFF metadata for georeferencing. [Recommendations] 
Generally the uncompressed baseline v.6 is seen as being the only suitable TIFF for preservation purposes although extensions such as GeoTIFF and TIFF/EP (both containing specialized metadata) are equally acceptable and based on this standard. Aside from the previously noted problems of compression, the LZW algorithm used within TIFF is based on proprietary software and files implementing this are considered unsuitable for long term preservation.
