Don,

not sure I follow this. If the contrast in the original scene is below 
whatever 
threshold is required for differentiation by the emulsion then although 
**you** 
(or I or John) may see it the film won't - and if it isn't recorded by the 
emulsion you can't get it back by dodging.

Look at:

http://gallery.leica-users.org/album164/SouthBeachSunset20050810

there was plenty of info that I could resolve by eye - the film, even at 
400ASA 
couldn't respond to it. The combination of eye and brain is a marvellous 
imaging 
device which has been worked on for maybe 2 million years or roughly ten 
thousand times longer than the camera.

You can only enhance information which is in the neg and that has to be done 
carefully otherwise you can create artefacts.

Do I misunderstand you?
