Polarising Crystals
This photography project was done in collaboration with a friend: Baptiste Jayet.
This is a series of pictures demonstrating the variety of colours one can achieve using polarisation - no colour filter was used during this project.
The basic setup is inspired by the technique of polarised-light microscopy; it can for instance be used for the analysis of crystals in stone.
In this setup a white light is directed towards the camera. Between the two are placed:
- a first linear polariser: this one is kept static
- a transparent object: this is what we take pictures of. In our case this is simply transparent tape laid on regular glass.
- another linear polariser: this one is rotated between shots.
Colour in such a configuration is the result of polarisation rotation induced by the object (the tape).
