Making Images

Now, we come to the making of images. We follow developments from the days of the early Greeks through to modern imaging. A photograph, although it may be truly a work of art, is just a two-dimensional image; there is no change in perspective when we look at it from different angles.

Holography, or three-dimensional imaging, was invented by the Hungarian physicist Dennis Gabor. We discuss what information the photograph lacks, its third dimension, and how we can encode that information to make a complete picture. We see that holography is a technique which has been rapidly incorporated as an art form and a scientific tool with practical and commercial applications.
