I'm getting a 14bit image from a CCD cam, and save it in a 16bit. The
problem is that, if I take only 2 gray values (greater than zero and less
than 2^14), the viewers that I try (imageJ and irfanview) take them as zero
and max valuo (black and white), they don't show the real color. How can I
fix it? I've tryed the next tags:

>  

The values are correctly saved, but it always show a full black and full
white value when there isn't any

> zero or 2^16 value. 

I am not immediately seeing a problem with your tags. Perhaps the pixel values are wrong, or perhaps this is a problem with these viewers.

Are you able to post a sample TIFF file somewhere so we can download it and see how it is constructed?
