A Short Course in Photography: 5&6

Chapter 5: Developing the Negative


  • Consistency and cleanliness pay off, the more dirty your film, the worse your prints will be
    • Just be careful me with every process
  • Something we don't have in the lab that I might find helpful is a photo sponge, i think i tend to damage my film when I'm trying to get most of the water off and this would help reduce the amount of contact I have with the negatives
  • didn't know photo flo was actually an optional part of this
  • during the development process
    • arrange everything first, make sure you know where all your tools are and that you have adequate space BEFORE turning off lights
    • before putting developer into the tank test temp again if the chemicals have been sitting out
    • *pour out developer about 10-15 seconds BEFORE the end of the developing period
    • when fixing the film:
      • check half way through to see if the film is clearing
      • if at half way the film is still milky the fixer is exhausted
  • after film has been exposed to light it is latent (not yet visible)
  • the negative becomes denser and darker the longer it is exposed to developer and with warmer temperatures
  • acidic stop bath helps extend life of the fix
  • fix dissolves any undeveloped crystals
  • development has a big impact on the exposure of the film
    • development will control the density of a photos highlights
    • exposure controls the shadows
  • a normally exposed negative should have:
    • good separation of highlights, midtones and shadows
  • push processing
    • changing the film speed on the camera in order to shoot in very dim settings
    • can have effects on developing
      • makes it easier to over develop your film
Chapter 6: Printing in a Darkroom

  • set up your station so you have three chemicals in a row and the water bath in a separate space
    • water bath can act as holding tank and you don't want it getting in the way of your processing
  • make sure to put paper in developer EMULSION side down
  • don't do the clearing bath until you're ready to put the print in the final wash
  • judging exposure
    • if pictures look too dark or too light do another test with the enlarger set at a different aperture
  • judging contrast
    • change paper or use a higher number filter
  • density: lightness and darkness of a print
  • contrast: difference in darkness between light and dark parts of the same print
  • adjust density first, then contrast
  • when the print looks good overall, go through and look for places that could be tweaked
  • burning versus dodging:
    • use cardboard and cover all areas except that which needs to be darker
    • vice versa for dodge
    • darkening a too light sky or highlighting a face are common ways of applying this method
  • cropping works best when you first take the photo
  • you can also use sliders on easel to change size of picture
  • spotting:
    • use liquid photographic dyes and a paint brush to remove unwanted light spots
    • the darker the spots, the more diluted the dye
  • scratching
    • you can use a blade to fine tune and scrape off any areas that are too dark
