Prerequisites

Objectives
Understand the phenomenon of colour, how it is perceived by humans, and its importance in photographic image production.
Recognise the subjective nature of colour perception and the limitations associated with colour reproduction.
Understand the principles of colour management and apply them throughout the different stages of photographic production, from image capture to printing, in order to improve control and consistency in colour reproduction.
Program
The phenomenon of colour:
The phenomenon of colour, its perception, and the historical development of colour theories;
The relationship between light sources, the object, and the observer;
Systems for organising and representing colour;
The importance of colour in photographic image composition.
Colour management mechanisms:
Colour in digital systems: CIE XYZ, CIELAB, RGB, and CMYK colour models and colour spaces;
Colorimetry and spectrophotometry;
Colour management mechanisms applied to different devices;
Characterisation, calibration, and profiling of photographic capture, display, and reproduction devices;
Colour profile conversion: Profile Connection Space (PCS), Color Management Module (CMM), and rendering intents.
Printing:
Image reproduction systems;
Photographic printing procedures;
Application of colour management procedures in the printing process, including the use of custom output profiles;
Analysis of different printing systems and substrates.
Evaluation Methodology
Assessment will take place throughout the semester through theory-and-practice assignments involving image production and submission, with a written component for analysis, justification and/or reflection. The practical component assesses the application of knowledge and procedures; the theoretical component assesses understanding of concepts, analytical skills and justification of choices. The theoretical component may be assessed through written elements included in the assignments and/or, when necessary, through a written test or stand-alone theoretical assignment. Active participation in class will also be considered.
Weighting:
Practical component 60%
Theoretical component 30%
Active participation 10%
Assessment and passing conditions:
- Students must attend at least 60% of both TP and PL classes. Failure to meet this requirement in either class type excludes the student from taking the exam. Exceptions apply to students with special status and duly justified absences.
- A continuous assessment mark below 7/20 excludes the student from the exam.
- A mark of 10/20 or higher exempts the student from the exam.
The exam includes a theoretical component (40%), assessed through a written test, and a practical component (60%), assessed through a practical exercise.
