ExifTool supports many different metadata formats including EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3, as well as the maker notes of many digital cameras by Canon, Casio, FLIR, FujiFilm, GE, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Nikon, Nintendo, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Phase One, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon and Sony.

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

• Added a few new Sigma lenses (thanks LibRaw)
• Improved handling of Canon CNTH atom in MOV/MP4 videos
• Changed PNG writer to place all text chunks before IDAT (not just XMP)
• Issue minor warning for any text chunk after PNG IDAT (not just XMP)
• Enhanced ForceWrite feature to allow "PNG" to be specified (to move existing text chunks to before IDAT without editing any metadata)
• Removed Windows "surrogate" warning for files that wouldn't be processed anyway
• Fixed some entries in the Minolta LensType list (thanks Jos Roost)
• Fixed identification of a Sony lens (thanks Jos Roost)
