Making a Black and White print

1.) List the materials (equipment) necessary to make a black and white print

  • Timers




  • Drying Cabinets




  • Tongs Or Spatula




  • Enlargers




  • Focusing Aids




  • Safelights




  • 2.) List the chemicals we might be using to make a print and where one would buy those chemicals
    Indicator (StopBath), Developer, Fixer & they can be grabbed online or near school campuses where they sell film supplies.
    3.) Summarize in one or two paragraphs the process from start to finish
    Print a contact sheet (a page of thumbprint sized images).
    In the darkroom, the chemicals are set up in trays, developer, stop bath and fixer. The negatives are laid out onto a sheet of photographic paper and exposed to the light of the enlarger. Once developed this sheet will become the contact sheet. The exposed photo paper is then placed into the tray of developer. Developing time for RC (resin coated) paper is 1 minute. Fiber based paper takes 2 minutes in the tray. Next step is to stop the developing process with the stop bath. The paper stays in this tray for 30 seconds and then goes into the fixer tray. RC paper stays in the fixer for 2 minutes, 4 minutes for fiber based paper. The final step is to wash the print in running water for 5 to 10 minutes. The contact sheet is now read to be hung to dry.
    4.) Post a photo of the equipment necessary to make a black and white print.
    1. emulsion - is a light-sensitive colloid, such as gelatin, coated onto a substrate. In silver-gelatin photography, the emulsion consists of silver halide crystals suspended in gelatin, and the substrate may be glass, plastic film, paper or fabric.
    2. aperture - The main function of a camera lens is to collect light. The aperture of a lens is the diameter of the lens opening and is usually controlled by an iris. The larger the diameter of the aperture, the more light reaches the film / image sensor.
    3. masking easel - device used to hold paper flat while exposing it to light from an enlarger. An easel border surrounding a print because its "arms" block light from striking the print paper's edges. 
    4. exposure - is the total amount of light allowed to fall on the photographic medium during the process of taking a photograph.
    5. safe light - is a light source suitable for use in a photographic darkroom. It provides illumination without the wavelengths of the light spectrum to which the material in use is sensitive.
    6. dodging - decreases the exposure for areas of the print that the photographer wishes to be lighter
    7. burning - increases the exposure to areas of the print that should be darker
