Objectives
In the course of the semester we study photographic processes that use bromide or silver chloride emulsion in black and white. Both direct darkening emulsions and developing emulsions for application on paper or photographic film are addressed. From a historical perspective, we will study the discovery and evolution of emulsions, as well as the improvements in the first 10 years of use. Reference will be made to the production processes of an emulsion, both industrially and on a small scale, in a photographic laboratory. We will study in detail how the choice of chemicals, the different production technologies and the variation of parameters can influence the characteristics of the manufactured emulsion. The program also includes the study of the theories of imaging and revelation, which made it possible to understand these phenomena. Special effects on emulsions and infrared emulsions will also be addressed from a practical perspective. Practical exercises will be performed with commercially produced emulsion and with various emulsions produced entirely by the students, in school, from the rudimentary materials and equipment. Infrared emulsions will also be tried.
Program
Experience with industrial photographic emulsion.
Experiment with infrared sensitive photographic film.
Preparation and test of direct browning emulsion.
Preparation and testing of emulsion washed for development.
Practice of printing on various supports (wood, textiles, paper, etc.), with the "artisanal" development emulsion produced in the context of a theoretical-practical class or using commercial emulsion.
Practice of producing a glass negative with the "artisanal" developing emulsion produced in the context of a theoretical-practical class or using commercial emulsion).
Last practical classes - Final project of curricular unit.
Evaluation Methodology
The assessment is continuous and consists of:
Presence, Participation, Attendance-5%
3 practical exercises-30%
1 written assessment test-25%
Final project-40%
Practical sheets or reports must be delivered within 1 week after they are made, at the risk of being shorted by 1 value for each day of delay. All elements of evaluation must be delivered until the last class of the contact period.
Examination period: The only elements of evaluation to be improved are, evaluation test and final project. The student proposed for the exam must a) perform an oral exam; b) to improve the final project, c) to combine the previous ones. After the improvement, the student must pass a minimum classification of 9.5 / 20 in the weighted average of the 4 assessment elements proposed above.
Season Appeal / Special / Finalist: The same strategy applies as the exam season.
