Developing a Panoramic Photograph
The first step in developing is to place matching sets of identifying numbers on the labelled box. Later, when the lights are out, the film is also numbered. Before turning off the light, the technician makes sure that everything he needs is in place.
While in darkness, the technician unrolls the film, and labels it with the matching number. Each roll of film contains two separate negatives. The film is then cut from its paper backing, and prepared for hanging.
As the technician hangs the film on a metal hanger, he attaches a weight to its bottom to hold it straight, and to keep its two sides from touching. The hanger is then placed in a tank of developer for ten minutes. From the developer, the film is moved to the fixer. Once the film is "fixed," the technician can turn on the lights.
With the lights back on, the developed film is removed from the fixer, drained, and placed in a washer for five minutes. The washed film is removed from the hanger, and taken to dry.
When the developed film is dry, the technician carefully examines it, watching for scratches or problems that may have occurred in developing, and then chooses the best negative for printing.
