Jean-David, Interesting material to read, cannot say I follow everything, but.. bounce@xxxxxxxxxxxxx] On Behalf Of Jean-David Beyer I have found that with problem negatives, a second exposure with the lens stopped down considerably can be used to burn the highlights. In theory, you could do even more, but I have never found it necessary. ..I guess you are referring to screen negatives, not "standard" B&W negatives? If you are referring to B&W negatives, could you elaborate a bit on this?
