Scientific photography and animal behaviour: A historical perspective

Louis Daguerre imagined that his invention would be useful mainly for artistic purposes or for personal use (portraits and travel diaries, etc.), but photography actually became a valuable ally of science. The observation and documentation of natural phenomena is one of the pillars of the scientific method. In this context, photography guarantees objectivity and authenticity in a way that other alternative techniques cannot. Moreover, as a visual tool, it gives us access to phenomena that cannot be perceived or processed by the human eye. A book on the expression of emotions published by Charles Darwin 150 years ago marked the beginning of scientific photography.
