A meta-comment.  I am a bit put off by the  characterization of devices which use non-linear transfer functions as "non-scientific".  

One almost gets the impression that the fact that ImageJ ignores transfer function information present in a .tif file is somehow a "feature".  I consider it a "limitation", if not actually a "bug".

If the image source happens to use a non-linear transfer function, I would consider it "unscientific" to ignore it.  I consider it only a little bit less bad to say "oh, that image source is 'unscientific' - so we won't support it".  More accurate is to say "ImageJ is limited to linear images".

Actually, upon reflection, I *do* consider it a "bug" that ImageJ loads a .tif image with a non-linear transform noted - and instead displays it linearly without even a warning (if, in fact, that's what it's doing).
