First Picture Taken
The first picture taken was in 1827. Photos are made in dark rooms by burning the picture on light-sensitive paper. Then having to put the photos through a series of chemicals to fully develop them. -
The Film
The film is a mixture of gun cotton that is dissolved in alcohol that then creates a small film. It is then mixed with silver chloride. This would help reduce the exposure time to seconds instead of hours. -
Chemicals used to develop the Film (Developer)
The developer is the substance that causes the iodide on the roll of the film to darken. This is to make it appear as though a light has been exposed to the film. -
Chemicals used to develop the Film (Stop Bath)
The stop bath substances stops the development process entirely. Stop bath is made out of acetic acid. -
Chemicals used to develop the Film (Fixer)
The fixer gets rid of all undeveloped silver iodide from the film. -
Colored Film
The first step into coloring a film is by bleaching the silver iodide off the developed film. The second step is washing the image to remove the chemicals and reaction products that are left. The film then must be dried. The color would then start forming depending on the subtractive color formation system. Subtractive color formation theory- When multiple pigments age combined, they subtract a greater number of light waves and create a new color. -
