[Image-SIG] how can I open 32 float tiff with PIL?

Also look at the compression type that seems to usually be more of a hangup than the bit depth.

If you have a type of TIFF that doesn't match one of the types it supports, you're out of luck.  You can try to convert the TIFF to a different format or try to patch the TiffImagePlugin.py module, which isn't trivial since you mentioned being new to Python.
