Chemicals In Black & White Photography

You can be in a darkroom developing your black and white photos with the right chemicals.


Black and white photography may seem like a blast from the past but it is an art that should still be taken seriously. After you have taken pictures on black and white film, start the development process. Developing black and white film consists of using certain chemicals to get the image from the negative onto the photo paper. It is recommended that you use protective gear, such as gloves, when handling the chemicals.


Developer


Developer is the first chemical used to develop photographs. When photo paper is dipped into developer, the picture instantly appears. True Art states that developer contains hydroquinone, phenidone and monomethyl para-aminophenol sulfate, which develop the photograph. Read the instructions on the bottle of developer to pour the appropriate amount into the tray. You will use a set of trays to develop your photograph.


Stop Bath


Stop Bath stops the developing process on your photographs. This chemical seals the image on the photo paper. Stop bath contains acetic acid. Exercise great caution when using this chemical. It is best to use gloves and tongs when handling the photograph and the stop bath chemical. The stop bath should also be placed in a tray next to the developer, since it is the next step.


Fixer


Fixer is the third step in processing your photograph. This chemical protects the photograph and also removes the stop bath. Photogs states that the fixing process takes approximately five to 10 minutes. After dipping the photograph into the fixer, place it into water for four or five minutes. At this point you may check your photograph to make sure the image is perfect.


Hypo Eliminator


Hypo eliminator is another chemical that is used to process the photograph. This chemical makes sure that all of the fixer is removed from your photographs. Hypo eliminator is not a requirement, but is commonly used to ensure there is no fixer left on the photographs. Use the hypo eliminator on photographs for two minutes.
