Not applicable.

The student at the end of the semester should be able to understand and contextualize photographic printing techniques using gold, platinum and pigment and their main characteristics;
Understand the applications and potentialities of the execution of different printing processes;
Know how to analyze the constituents of materials and reagents of photosensitive solutions;
Understand and Interpret variables adjacent to photographic printing processes: density, contrast, saturation, detail reproduction and veil;
To know the particularities of the chemistry involved in the oxidation-reduction reactions of the elements present in the photographic printing processes addressed.
Analyze and criticize the results in the presence of the teacher and colleagues, for the development of autonomy and critical sense.
Autonomously execute a creative project using one or more gold, platinum and pigment printing techniques.

To achieve the rigor necessary to experiment with gold, platinum and pigment printing techniques, this course proposes teaching about the nature of materials and the methodology of each photographic experimental process.

1) Digital production of large format arrays.
2) Digital matrix calibration methodology for linear sensitometric response imaging.
2) Analysis and testing of optimum media characteristics (paper, glass, acetate, etc.)
3) Analysis and comparison of pigments and their origins, extraction forms, stability, characteristics and incompatibilities.
4) Research on the most inking plant species to perform an antotypy print quality.
5) Tests and combinations of different concentrations of sensitizing solutions in order to obtain higher contrast, detail and density.
6) Techniques and strategies to promote the longevity of the images produced.
7) Archive and packaging concepts, good practices.

Evaluation Methodology
The assessment is continuous and consists of:
• Presence, participation, attendance - 5%
• 4 exercises practical - 25%
• 1 written assessment test - 20%
• 1 research paper - 15%
• Final project - 35%

Practice sheets and / or reports must be submitted no later than one week after the exercise in question on the risk of 1 value penalty for each day of delay.

All assessment elements must be presented and delivered by the last class of the contact period.

However, if the student needs more time to complete the final project, the presentation may be postponed to the exam season without prejudice to the assessment. Since the only component that can be evaluated during subsequent seasons is the final project.

Students who do not obtain a final grade equal to or higher than 8/20 are excluded from subsequent seasons.

Method of interaction
Expository, lectures taught using the projection interface of slides that articulate with laboratory practice where the experimentation and application of the knowledge acquired in the context of lectures.
