TIFF/EP is a subtype of 
TIFF developed as an ISO standard for electronic photography, ISO 12234-2, titled "Electronic still-picture imaging – Removable memory – Part 2: TIFF/EP image data format."  The TIFF/EP is based on a subset of 
TIFF and a subset of the JEITA Exif standard, with some differences and extensions.  The 2001 standard has not been adopted per se by most camera manufacturers, although some proprietary 
raw formats and the 
DNG format claim to be compatible with TIFF/EP/.
