I did all my best to smile

This artistic-scientific research explores the role of perception, interpretation, and expectation in contemporary portrait photography, with a particular focus on the smiling portrait. By combining insights from neuroscience (predictive processing theory ) and philosophy with photographic experiments, the research challenges the apparent transparency and legibility of facial expressions (in particular) and photography (in general).

Contrary to traditional views that directly link a smile to happiness, this study argues that meaning is a dynamic and contextually determined construct.

The project contributes to the theoretical development of predictive processing within an artistic context, while at the same time casting a critical light on cultural conventions, emotion recognition technologies (such as FER), and visual representation in the digital age. The smiling portrait is not treated as a subject, but as a tool to explore broader questions about meaning, context, and visual perception.
