Hi Beth, I had no try the 16 bit TIFF support of Mathematica. But I assume it is not implemented. I can offer you only my PNG bitmap package that *has* the feature to import and export 16 bit PNG images. So if your original program can write 16 bit PNG you should donnload the MathPNG package from http://www.mpae.gwdg.de/~kuska/mcpng.html and transform the PNGBitmap[] object to a normal matrix.
