I did a test on TMAX 100, developed in HC 110. I followed the BTZS procedure, and plotted the data in the "Plotter" software as per instruction. I ended up with a very narrow SBR range 3.1 to 4.3, and a chart of EFS versus N numbers, ranging only from N + 2 to N+3.
Can anyone help me out as to why the narrow ranges?
I did a simlar test with the same film, but with D-76, and the SBR range is quite a bit wider, 4 to 11.3, and it plots the N ranges from N-4 to N+2.
