Perhaps it depends on the camera; or perhaps Canon puts all of the additional information in the MakerNote. For my oly, the MakerNote contains next to nothing: %exif -'|' Bird_0001B_20111214_300mm_IS_30s_Flicker.jpg MakerNote contains 7 values: Speed/Sequence/Panor|Normal/0/0 Camera ID |OLYMPUS DIGITAL CAMERA Unknown Tag | Unknown Tag | Unknown Tag | Unknown Tag | Unknown Tag | Another possibility is you are missing some info you aren't aware of. I'm curious to know if Canon stashes things in other places; I know nikon does similar to the way oly does as reported below; exiv2 -u -p a on a nikon raw file shows 112 nikon specific values. %man exif ...
