Hi Parker, I teach traditional Talbot-Klic dustgrain photogravure as well as photogravure with my analog aquatint screens. I encourage newcomers to standardize their workflow with a screen before proceeding to dustgrain. My studio is in Carolina Beach, NC just 30 minutes from Wilmington ILM airport. The positives are made digitally and I will be adding QTR linearization to my workshops this summer. The workshop is 3 days long and in the middle of the week when beach accommodations are more affordable. Please see this page for more info: http://www.capefearpress.com/gravure_workshops.html
