A film is a roll of images that can be projected.
The concept of filmina is developed with two components: the noun film (a film) and the suffix -ina (which can be used to form diminutive type nouns). The term refers to a slide .
The slides, meanwhile, are positive photographs that are captured on a transparent material . Furthermore, the notion can refer to the pages that make up an exhibition made with a computer .
What is a film
From these ideas, we can easily understand what a film is. As slides are photographs , it can be said that a film is a still image that is obtained through the incidence of light on a sensor or on a sensitive area.
Specifically, we said that they are positive photographs . This means that the images reproduce the colors and dark and light tones that can be seen in the real world .
Generally, a roll of film containing between 30 and 50 images is called film film. This 35 millimeter photographic film is installed in a projector so that images are displayed on a screen or flat surface (such as a wall).
The concept of film can be used to refer to a digital presentation.
Rise and decline
For almost half a century, filmstrips were very popular in the field of education . This is because they allow teaching materials to be displayed in a simple way, taking up little space and offering easy rewinding. Furthermore, they do not usually break.
Beyond these advantages, technological advances made film films become archaic. Although the display of photos can be synchronized with sound , in the 1980s the video cassette became popular as an inexpensive audiovisual medium. Thus, since then it has been more convenient to project audiovisual content (previously on videocassette, today on DVD ) than a film.
The films in class
Although, as we already indicated, their current use is limited, filmstrips can still be useful in a class . The teacher has the possibility of showing the images while developing an explanation, with which the photos function as support for their statements (or, conversely, they can base their speech on what is shown on the film).
The same mechanism can be used with digital films or slides that are part of a presentation made with a computer. The famous Microsoft PowerPoint program, for example, allows you to create these images, integrate them into a presentation and display the resulting work.
The Argentine president's comment
Due to the aforementioned technological change, filmstrips are now used very little and even the word has become unusual. In this context, millions of Argentines were surprised when the nation 's president, Alberto Fernández , alluded to the films in a press conference.
In April 2020 , to show the advance of COVID-19 worldwide, the president used films that also helped him explain the measures he had taken with the aim of reducing infections . Fernández not only used the films, but also mentioned the term in his presentation.
Many journalists associated Fernández 's action and comment with the customs acquired in his work as a professor at the Faculty of Law of the University of Buenos Aires ( UBA ).
