The error (TIFFReadDirectory:Unknown field with tag 34595 (0x8723)
encountered) only shown on the very first batch of test R-2 images.
The official release R-2 data do not show the error.

I think this may be more of an OpenEV question, than it is a GDAL
question.  You can directly select the uncalibrated numbers by
using the appropriate subdatset name with GDAL.  You can use gdalinfo
to see the subdataset names of a dataset.

Hmm, this is odd. Would it be possible to make a dataset demonstrating
this problem available?
