In 2020 ISASI brought Antigone Marino’s contribution to Città della Scienza for the Physics Seminars born from a collaboration between the National Institute of Nuclear Physics with the National Research Council and the Physics Department of the University of Naples Federico II.
Antigone Marino presented on February 12 “Physics and photography: how much science hidden in a shot?”. Click. A noise that many associates with photography. It is the noise of the shutter that allows the light through, to impress the sensor. A sort of eyelid for a true digital eye: the camera. We will start from the biomimicry of this technology, which imitates the human eye, to see how technology has managed in a few centuries to pass from the pinhole to single-pixel cameras. A photograph hides a lot of science: chemistry, physics, materials science, and even mathematics. We will review the optical phenomena that allow us with a simple click to reproduce what we see, from refraction to color theory. And we will see how the understanding of optical phenomena has allowed this technology to evolve so rapidly.
