May 2017: 70th Season of the Cannes Film Festival
Every spring, the city of Cannes, France welcomes film lovers from all over the world for the annual Festival de Cannes. This year, the event will have its 70th season of celebrating the art of film and previewing new films of all genres from 17 to 28 May at the Palais des Festivals et des Congrès.
Today’s films are almost exclusively digital, and everything from the cameras they’re shot with to the computers they’re edited on require all sorts of metals and other raw materials like silicon. But when the Cannes Film Festival began 70 years ago, films were still made using actual film.
Film itself was discovered by accident in 1727 when German doctor Johann Henrich Schulze mixed chalk, silver and nitric acid to make silver nitrate. He found that when his solution was exposed to sunlight, it changed color, and he was able to make imprints on the solution with sunlight and cutouts. Over the next few centuries, the film we’re familiar with was developed and improved upon numerous times, but the same basic principles still applied.
