How does a photographer use light waves to make a great image?
Reece McCready is an award-winning young photographer who specialises in portraits. Presenter Jon Chase joins him and his subject, Lola, to see how they use light waves. As Reece uses his camera and lighting gear, Jon follows exactly what happens to the light waves on their journey from light, to Lola, to camera.
Jon investigates the two sorts of reflection – the kind you get with a mirror, and what happens when light reflects off Lola’s face.
Then he looks at how the lens on Reece’s camera gathers the reflected light and focuses it into an image, using refraction. And finally, how the sensor in the camera turns the light image into an electrical signal that can be saved.
