Also, this negtaive printed well on Fabriano, but requires less
correction than was applied to the negative. I derived and reported a
possible curve to be used with the Fabriano paper (again, 1:7 Pt/Pd,
double-coated and developed in potassium oxalate #2).
I have not tried the reported curve on a print yet -- I will report those
results in a couple of weeks. Charlie Palmer, who contributes here, may
have some results to report even sooner than that. The point is that
this curve is still EXPERIMENTAL, and should be taken as such.
After entering the curves in the Photoshop curves dialog box, I noted
some irregularities in the curve, which I have smoothed out to make a
nice sweeping curve. I am including here the values of the adjusted
curve. I will be testing this curve within the next couple of weeks, and
will report back.
