Removing the film

• In complete darkness remove the film from the
  cassette using the can opener
• Roll the film onto the spiral (this takes
  practice try it first using exposed film in
  normal lighting)

5
Loading the Film

• Cut off leader
• Feed end into the opening of the spiral
• Hold one side and rotate the other until it stops
• When the whole film is on the spiral cut the
  spool off

Developing the Film

• Three steps
• The developer activates the light sensitive
  particles in the film
• The stop stops the activation of particles in
  the film (can reduce the appearance of over
  exposure)
• The fix protects the photo from change over
  time, and exposure to ultra violate rays.
• Times and chemical concentrations vary with film
  manufactures, refer to your manufactures
  specifications for specific values

Rinse the Negatives

• Wash away the chemical residues by running fresh
  water into the developing tank for 30 minutes
• Dish soap can prevent water stains

Common Problems

• Completely clear film not exposed
• No edge numbers and clear hasnt been developed
• Totally black exposed to light, in camera or
  darkroom
• Light leakage foggy, streaks on negative
• Lines on film stress marks caused by film being
  forced into the spiral
