Input offset is an approach that maintains contrast near black, but it can be hard for some displays to match the response curve needed, and some people may not like the way the dynamic range is not compressed at all (Normally a sigma type compression is more visually desirable). For displays with inherently low black level, output offset may be the best choice, and in other cases some intermediate choice may give a more acceptable subjective result. So you really need to try it out and see for yourself. Graeme Gill.
