	This question is a little strange, a little bit tough to know
what is really being asked, since among the plethora of "tiff images"
there are those whose scale is gray. TIFF (tagged image file format) is
in effect a glorified (flexible) "header" for a wide variety of image
types (bi-level, gray-scale, palette-color, direct RGB, to name a few),
many of which can be compressed in a variety of ways (ccitt, rle, jpeg).
	So I don't understand the question - is the question one of
how to take a gray-scale TIFF image and exploit the gray-response curve
to produce a suitable rendering in a given display environment?
