Digital Negative - an introduction to historical techniques

Workshops are conducted by: Krzysztof Strzoda

Date: on request (standard group 3-5 persons, individual/solo possible)

Workshops duration: 16 hours (Saturday and Sunday)

Price: on request/ask by e-mail

Registration/questions: edutechpl [[at]] gmail [[dot]] com

Description:

The workshops is dedicated to all creators, artists who start work in historical techniques or want to improve the already performed process of creating their own works based on digital negatives. The training is recommended for all those who plan to participate in the Platinotype / Palladotype workshops.

The aim of the workshops is to learn how to prepare a digital negative and to introduce you to historical techniques on the example of a New Cyanotype (*) or Kallitype (**). Thanks to participation in the workshops, you will learn how to prepare a perfect digital negative. Perfect for you, that is, meeting your own requirements and expectations regarding the final image prepared in historical photographic techniques. The workshops cover theoretical and practical issues of preparing a digital negative with a wide tonal range from digital photographs or scans of analog negatives. The issues of creative influence on the prepared negative will also be presented in order to obtain the expected results. You will learn to use a modern and at the same time economical technique of your own preparation of photosensitive materials (covering the paper with a sensitizer / photosensitive solution) and make your own prints using the Cyanotype and / or Kallitype technique.

During the workshops:
- you will learn the methods of process calibration,
- you will prepare two digital negatives for work in the technique of a New Cyanotype or Kallitype with the help of a teacher,
- you will learn how to prepare a print using the technique of a new Cyanotype or Kallitype,
- while learning how to coat, you will prepare 10 papers coated with a sensitizing solution
- you will make prints in the New Cyanotype (NC) or Kallitype technique (up to 4 pcs).

We provide all participants of the workshops with:
- materials necessary to work in the workshops program (reagents, papers, foils, etc.),
- a professionally equipped studio / darkroom,
- printing of two digital negatives,
- drinks (coffee, tea, juices, water min.) during the course.

At the end, the participant receives a compendium of knowledge from the workshops.

Maximum group size - 5 people

(*) New Cyanotype (NC) - POP technique developed by Mike Ware i 20th century, characterized by a wide tonal range and greater persistence to the environment than the traditional cyanotype
(**) Kallitype - a DOP technique invented in the 19th century, using iron and silver salts
