Making Adjustment Curves for Digital Negatives

This was designed for making photogravures (polymer), but will work for any alternative/historical photographic process that requires a negative/positive printed on a transparency with an inkjet printer.

This is a video version of the workflow from the book
The video was made for one of my classes last year.  The class already had lessons on intaglio printing, finding minimum (and optimum) exposure times, as well as a quick introduction to setting up the scanner to digitally capture an image of an intaglio print with multiple step wedges.

Here are links to many articles and videos.
