The Camera-Eye

When experimenting with light and optics, there is without a doubt one thing that cannot be left out - the camera.

When visiting the Duchamp exhibition in the Tate Modern, a sketch of Francis Picabia, who was like many other artists very interested in machines at that time, attracted my attention. ‘The Camera-Eye’

In this picture you can see the refraction of light in a Perspex blog.

If we are really going to do something for the final project with light, it would surely be useful to refresh our knowledge of light behavior.

Here you can see the same phenomena. The water with a different density than air, makes the straw look as if it was broken.
