With a Canon 1D X, when I look through the view finder or look at the "Info" panel (having set up particular options), the camera knows if it is tilted slightly left or right and also knows if it is tilted slightly up or down. Or, to rephrase, it has an electronic level within the camera. Is this information stored in the metadata when the picture is taken and, if so, what is the name of the fields?
When I dump out the metadata using exiftool -a -u image.cr2 I do not see anything that might be it. Google doesn't seem to find any hits. "Crop Angle" is not in the metadata.
I'm not talking about "Orientation" of Horizontal or Vertical. I'm more interested in the slight tilting of the camera.
