Stephen, thanks for those curves. It shows that for a 3 stop overexposure , highlights (up to Zone VIII ?) will remain uncompressed. However in my process when I consider one more highlight zone than you do plus one more stop of over exposure, my theoretical max neg density will be 2.1 which is right at the limit of Ilford's curve and beyond that I assume it begins flattening out. There appears to be very little published data available for the shoulder sections of characteristic curves across all the development times. My next post will talk more about the shoulder sections.
