Hi, The PIL has some fundamental architectural problems that prevent it from dealing easily with 16-bit TIFFs, which are exacerbated on little- endian platforms. Add to this a thin sheen of various byte-order bugs and other problems in the __array_interface__, and it's really hard to get consistent loading of 16-bit tiffs across platforms. (I and many others have submitted patches for these issues to no avail.)
A while ago, I tried to see if I could graft the image file format parsers from the PIL onto a byte-loading backend that used numpy. Unfortunately, I really couldn't -- the parsers assume too much about the problematic architecture of the PIL. I do have a private fork of the PIL that I made which remedies the bugs and above-mentioned architectural issuse, and works cross- platform, and with any endian system. (It's very restricted compared to the regular PIL -- basically it just does image IO and then converts to numpy arrays.) I haven't released this because I don't really want to make trouble -- and we're promised that a major revision of the PIL is in the offing which will fix these troubles -- but I'm happy to send the code out to those who actually need reliable 16-bit image IO.
