Anyone doing multi-negative processes using PiezoDN workflow? LIke gum over Pt./Pd. or CMYK gum or carbon prints? I have a workflow question.
I want to make a linearization curve for a gum layer over a Pd. print. This Pd. print was made using a PiezoDN linearization curve. Now I want to add a gum layer. And this gum layer will only target from L=0 through ~33.
I am thinking about printing a 129 step chart using my linearized Pd. curve. After this print is dry apply my gum layer and print and process accordingly. Measure the resultant 129 steps (the gum over Pd. print) and create a linearization curve. Test this new curve with the same workflow as described.
Now I have two curves: one for the base Pd. print and one for the gum over Pd. Like any alt. process controlling and repeating my darkroom workflow is a given. If I want to target only the shadows then prior to printing the second negative, i.e. the gum over Pd. negative, I would make the necessary adjustments in PS targeting the shadows.
Does this workflow sound correct? What am I missing?
