Monographic Courses

Historical Techniques II

In this course, we will practice several techniques of manual photographic printing. These techniques are part of what we call historical techniques, alternative photographic processes or old processes, because they date from the 19th century in their majority, although there are some developed during the 20th century. These techniques make it possible to cover paper and other surfaces with various sensitive materials in order to copy images on them through the action of light on chemicals. In these processes, the light-sensitive cover is prepared by hand and applied to different supports to then copy images by contact. You can work with images obtained with any camera, frames or drawings. All this makes alternative processes very versatile when working on different photographic projects. The course is divided into two parts. In this second part, we will delve into four different printing techniques, which will allow us to obtain multiple creative possibilities. Each session will deal with a new technique with pre-recorded materials and technical documentation that will lead us to discover the processes with which photography began.

April 8, live online, ENG 19-21hs (Hora de España - GMT+2)

Meeting: Experimental photography: concepts, debates and techniques with Pablo Giori

SESSION 2: ARGYROTYPE (New Argentotype)
April 15*

Dr Mike Ware's variation of the argentotype was invented by Sir John Herschel in the 19th century. We will use silver oxide, sulfamic acid and ammonia ferric citrate to create a single sensitizing solution. The copies obtained have a great richness in the tones and depth in the shadows.

SESSION 3: KALLITYPE and Iron Techniques

April 22*

This is another of the iron-silver techniques that is often confused with Van Dyke Brown. We will combine two solutions to prepare the sensitizer: silver nitrate and ferric oxalate. After exposure to light, a development process will need to be carried out that, depending on the materials used to prepare it, will make the print take on different shades.

SESSION 4: ALBUMEN PRINT: a Silver Nitrate Techniques

May 6*

In this case, the support is prepared with albumen (egg white), which previously underwent a salting process. Albumen-coated surfaces are then coated with silver nitrate solution to make them light-sensitive. The image is formed on the surface of the albumen, resulting in a brilliant print, with great definition and depth in tones.

SESSION 5: PIGMENTED TECHNIQUES: Gum Bichromated, Monochrome in Colour and Trichromy

May 13*

Gum Bichromated printing allows images to be copied on paper, cloth, ceramics and other surfaces. You can work in several layers, which allows you to make colour copies. It consists of copying a negative by contact on a surface that has been previously sensitized with gum arabic and potassium bichromate.


May 27, live online, ENG 19-21hs (Spain Time - GMT+2)

Presentations of student work, viewing of references and dynamics with questions

* When the class is pre-recorded, it is sent on the indicated day at 8 in the morning and each student can watch it when it suits them best.


TEACHER: Célica Véliz  @superficies.sensibles


Photographer, Professor of Visual Arts and Ceramist.  

She was born in Buenos Aires, Argentina. She trained in the city of Tandil at IPAT and at the School of Ceramics. At the end of her studies, she became interested in the photographic techniques of the 19th century and began to investigate and experiment with them.  

She currently coordinates experimental photography workshops and alternative photographic processes in his virtual space "Sensitive Surfaces" and in the Cooperativa de la Imagen (CABA). She has given workshops and talks in several cities in Argentina and Mexico.

She has made several individual exhibitions in museums and galleries. He also participated in collective exhibitions and festivals in Argentina, Colombia, Ecuador, Mexico and Spain. She has been a selected artist of EXP.21 and EXP.22 to give workshops, conferences and exhibit her work. Furthermore, she has published the mini-books “MADER” (2014), “El Cuerpo Roto” (2019) and “Las Vías de Escape” (2020).
