QTR-Quadtone RIP

Some links for those who are looking for alt-process info QTR and Non-QTR related:

For those wanting to learn the basic QTR/Driver ways of dig neg production I suggest Ron Reader’s book (http://www.lulu.com/shop/ron-reeder/digital-negatives-for-palladium-and-other-alternative-processes/paperback/product-12438503.html <http://www.lulu.com/shop/ron-reeder/digital-negatives-for-palladium-and-other-alternative-processes/paperback/product-12438503.html>)

For those wanting  dependable full-featured negative production workhorse, PiezoDN does a much better job at density control than most “qidf-built” curves because of its unique overlap structure and tools and chemistry (more data points as Richard pointed out) and that documentation and manual is ever-growing at piezodn.inkjetmall.com <http://piezodn.inkjetmall.com/> along with some stellar science and knowledge-bombs from Keith Schreiber on that forum.

A good primer on how to handle any alt-process and it’s density requirements can be found at Mark Nelson’s site www.precisiondigitalnegatives.com. It’s a great read if very technical. (He uses Keith’s idea of optimizing based on UV absorption of color ink to handle dig-neg printing from basically any driver or printer out there).

//

The alt-photo list is also a great place to ask questions about bulbs, film density, and workflow/practice: altphotolist.org 

//

For those wanting to deep-dive into the esoteric soul of Pt/Pd I suggest taking David Michael Kennedy’s workshop. I’ve heard too many good things about it and am saving up the $$$$ to go myself. http://www.davidmichaelkennedy.com/workshops

//

For those wanting to learn both Pt/Pd and digital negative calibration, we offer workshops at Cone Editions as well. I suggest learning the Pt/Pd process first though so the learning curve is less steep. 

//

Lastly, for those just wanting to get cracking on prints with calibrated PiezoDN negs, and to learn about process and not just neg making, we sponsor Maine Media Workshops HAAS (historical process teaching darkroom) and Brenton Hamilton (the instructor) is a genius. You learn Cyanotype, Kalitype, Palladium, Zia, Salted, Gum, all sorts of stuff. It’s nuts and I highly recommend it. The workshops fill right after they are listed though so sometimes it can be hard to get in.  https://www.mainemedia.edu/workshops/photography
