After reading the title “The Way in which Chemistry Plays a Major Role in Movies”, you all may be contemplating the multifarious relationships evident among characters in movies or perhaps the complex interactions between two people, which can occasionally be referred to as chemistry. However, the term “chemistry” in this particular scenario embodies absolutely no affiliations with any attributes that may be intimating a relationship. Rather, it inhabits its orthodox definition as a branch of science and the study of the composition, structure, and properties of matter as well as the changes matter undergoes. Although it may not appear patent at first, chemistry has numerous, profound roles in the making of all movies. To begin with, simply think about how a movie is made. By a director, right? WRONG! I mean yes, but think deeper! What does a director use to make a movie? A camera. How exactly does a camera capture the moments of life, and later display the moments onto the big screens? The correct answer is that a camera utilizes a vital component that is known as the film. The film, a major constituent of a camera, is a pliable and attenuated strip of plastic with light-sensitive emulsion for exposure in a camera, fundamentally used to produce motion pictures. The primary chemicals (substances that have a definite composition) and compounds, which are made from the atoms of at least two chemically-bonded elements, become involved when actually developing the film. The first layer of a film is a protective coating which protects the emulsion layer that has the gelatin and the silver halide crystals in it. (Higher speeds of film have multiple layers of emulsion.) The next layer is the film base, which is a polymer that is chemically stable and flexible. The last layer is the anti-halation backing, which precludes reflections off the back of the film
Moreover, the origins of photographic processes date back to the 1800s and yet were still astonishingly dependent on chemistry. The beginnings of photographic processes were devised by William Talbot during the 1830s. Talbot’s procedure consisted of continuously rinsing paper in baths of saltwater and silver nitrate (AgNO3) solution, hence depositing silver chloride (AgCl) in the fibers of the paper. Afterwards, this wet piece of paper was exposed in a camera till a dark, silvery image appeared in the light-struck regions, and the remaining silver chloride (AgCl) was removed by washing it with a concentrated salt solution. By waxing or oiling the negative sheet, Talbot made the paper translucent, and then by making an exposure of diffuse light through the negative onto another sensitized sheet, he produced a positive image. Therefore, an interminable number of copies of a photograph could have been generated from any one negative. In other words, behind the multiplex concept of filmmaking and photography lies a simple (or not so simple) answer: science, and specifically, chemicals and compounds, which are all ultimately a part of chemistry. In the following centuries, as photographic processes advanced, mechanisms of processing undeniably altered to later on, produce color and digital photography.
All in all, behind a movie is a director, behind a director is a camera, behind a camera is a film, and behind a film is the work of chemistry. As technology continues to expeditiously evolve, along will come the emergence of further advanced photography, and along, in the years to follow, will come the institution of an augmented role played by chemistry throughout the film industry via the concept of photography.
