How to make a pinhole

This is a tutorial on how to build a pinhole or hole camera obscura using a can with tracing paper. A matte black spray paint and black cardboard were also used to avoid internal reflections.
In this video, a theoretical explanation of Geometrical Optics of Physics about the functioning of the darkroom is also given, as well as some practical applications for measuring distances using a similarity of triangles to light rays. This physics experiment brings a verification to the principle of straight light propagation, as the projected image is inverted both vertically and horizontally.
Make your camera obscura yourself!
