Making Wet Plate Collodion Negatives & POP Printing

May 5 - 6, 2018


PREREQUISITE: You must have knowledge and hands-on experience with the wet collodion positive process in order to take this course. If you have any questions, please contact Quinn.

This is real photography for serious artists and photographers! An intensive, three-day, hands-on workshop that covers allaspects of making Wet Plate Collodion negatives; including redevelopment, intensification and making Salt and/or Albumen prints from the negatives.

This course is designed for people who have worked with the positive Wet Plate Collodion process (Ambrotypes, Tintypes, etc.). Darkroom experience is preferred and students should have a good understanding of traditional silver gelatin negative making. Large format camera experience is preferred, too.

Students will get to see the negative making and redevelopment/intensification process executed from start-to-finish and the workflow methodology that Quinn uses for his work. He will also demonstrate making a Salt Print and/or Albumen print from the negative.  

Quinn will do an in-depth segment on chemistry. Chemistry for negatives is different than positives. It’s subtle but affects the quality of the negative. He will also work through the chemistry for redevelopment and intensification; two very different methods for making negatives. Each individual chemical will be discussed and described in detail. Students learn about each chemical’s function and purpose in making and redeveloping/intensifying negatives – this is very important as it relates to troubleshooting. Safety, storage and handling are also major components of this segment. Students will participate in making each of the chemicals for the process.

Plate Making
This workshop will use Half Plate size. Students will have the opportunity to work in both of these formats. The second day of the workshop is devoted to making negatives which includes preparations, glass cutting, cleaning, etc. pouring plates, sensitizing plates, exposing plates, developing plates, fixing plates and varnishing plates. The third day will cover printing processes.

Negative Redevelopment & Intensification
Quinn will cover both of these techniques and show the difference between them. Students will learn when to use hardcore redevelopment or a simple intensification.

Printing Out Paper (POP)
Each student will select their best negative and make P.O.P. prints from it. This course will not cover making Salt and Albumen paper, but will provide students the paper and supplies for printing the negatives. We may do some oil and or Aristotypes - we leave this open.

Critiques & Troubleshooting
At the end of the third day, there will be an overview/critique about the images made. This critique is based on troubleshooting – things that went wrong and things that worked. It’s a very valuable part of the course.

What’s Provided?

  • You can attend the workshop with nothing but a pen and notebook. Cameras, chemistry, substrate and facilities are all provided. You are welcome and encouraged to bring your own camera (if you can). Using your own equipment helps when you start making images on your own. Be sure to have a Half Plate and/or Whole Plate insert. 
  • You will receive a copy of Quinn’s manual, “Chemical Pictures: Making Wet Collodion Negatives”. The manual will be used through the course.
  • There will be drinks available at the studio (coffee/espresso, water, soft drinks, etc.) throughout the day.
