Part Two: Practical ways to show films

The method of displaying the film depends on its type, ie:
(a) If it is a roll film.
(B) or a flat sheet film cut film
(h) or glass sensitive plate.

It also depends on the length of the film if it is wrapped, or on the number of glass panels or flat films.

(d) Cinematic films have special ways of showing them, as they may be hundreds of meters long sometimes, which calls for the use of mechanical means that work with electrical forces to regulate all stages of showing.

In general, the usual methods can be summarized as follows:


First: Showing the wrapped films manually in a basin or dish dish:
It is the method followed by most amateurs or professionals with limited capabilities. In this method, the sensitive celluloid tape is removed from the paper that covers it (Fig. 11), then the film is washed with water to soften it, and to remove the anti-halation layer, and also to facilitate the work of the appearance solution. Then the film moves a continuous movement in the display basin, so once the right hand rises and then descends, the left one rises again (Fig. 10) and so on until the display is completed, taking into account that the lower part of it remains immersed in the solution throughout the period, and without scratching the back surface of the film as a result of its friction with the bottom of the basin Therefore, it may be more appropriate for the beginner, who performs the display operations manually, to use a glass container with a circular bottom, (Fig. 12) so that the back surface of the film does not rub against the bottom of the container.

Likewise, it may be preferable for the beginner to start showing orthochromatic films that are not sensitive to red rays so that he can follow the progress of the display process and see with his own eyes (in the existing red safe light of these films) how the film's blackening gradually develops during the exposure period, as he watches for himself what happens. The film undergoes changes during the installation process.
