The Mystery behind Black and White Photos

The photography industry continues to gain popularity even with the advancements in digital cameras and video technologies. While consumers can now take pictures with high resolution using their point-and-shoot devices, there is still a need for professionals. But moving back in time, have you ever wondered how pictures came to be and its evolution from the traditional monochromatic to the vibrant coloured images? Before memory cards, USB cables, and printers existed, how were they processed? Well, if you want to find out, then you should familiarise yourself first about the development of the black and white film.

1. The film is immersed in a developing agent. In the early days, there are various chemicals used such as chlorohydroquinone, ferrous oxalate, hydroxylamine, ferrous lactate, ferrous citrate, Eikonogen, and many others. Presently, the mixture used still consists of several items with an aqueous solution that helps delay oxidation of other agents. What happens during this procedure is that the silver ions on the film turns into metal especially on the latent image sites, which refers to the invisible image produced due to the exposure of the film to light. With proper control of temperature, agitation, and time the grains will become pure silver.
2. After one or two minutes, depending on the paper used, it is then removed from the developing agent. Once excess liquid is completely drained, it is then placed in a stop bath to halt the development of the film or plate by neutralising the developing chemicals.
3. The film strip is washed with water until all the chemicals used in its processing is completely removed. Afterwards, it is then dried and then cut into negatives. In order to make the pictures visible to the human eye, it has to be printed on a photographic paper which is also considered a light-sensitive material.
