in Ralphs post http://www.apug.org/forums/viewpost.php?p=1119941 does he refer to a stouffer with 21 or 31 steps, by measuring the exposure off of step number 11? either way step number 11 on a 21 stouffer should be the same as step number 16 on 31 stouffer...or am i wrong?
the density of step 16 on a 31 stouffer is around 1.5....
what Muihlinn said it should be at a density of 0.6 so that would be somewhere between step number 6 and 7 on a 31 stouffer...?!? so which step number is the one to measure the exposure of off?
Thank you Bill Burk for your answer...i have attached my (failed) test results from march for 120 rollfilm hp5+ and fp4+...could you please write your take on the results...i appreciate your knowledge and insight into the topic very much...as i am lacking there.... ;-)
Thank you and best regards,...Christoph.
