i did the test from yesterday like Michael http://www.apug.org/forums/viewpost.php?p=1480607 because he got good results with that...at least what i can read out of his posts in this thread http://www.apug.org/forums/forum37/8...pplied-17.html
Bill, what are you suggesting? to do the test (by contacting) the same as i did yesterday,...but use only a 3 stop overexposure on the lightmeter?
regarding densities...Ralph suggests to take absolute density readings...so to null the densitometer when there is nothing in the light path...so i did it that way measuring all the densities on the stouffer
is it better to take relative readings...nulling the densitometer to an unexposed piece (=B+F?) of the tested film and then read all the densities relative to that first null measurement...is that a reading relative to base and fog (so b+f is subtracted from the measurements)...?
