  1. 2. Paper negative “salt prints”.
  2. 3. The development process used today for colour negative film.
  3. 8. A type of film that is known to become sticky as it degrades over time, adhering to adjacent materials.
  4. 9. fading, The fading and staining of emulsions that take place in the absence of light.
  5. 13. Careless handling of films and photographs can lead to ________ on the surface.
  6. 14. Known as 'safety film'; gives of a vinegar smell when it deteriorates.
  7. 15. A process that was one of the first non-silver technologies, adopted as a copying technique; "blueprint".
  8. 17. When cellulose nitrate film deteriorates it produces an ___________ reaction.
  9. 18. Photographs and films should not be stored in rooms with ______ temperatures and relative humidity.
  10. 19. Black- and-white negatives and prints should be stored at a temperature around _____° C.
  11. 20. Known as a good binding medium for its drying properties and how well it protects silver halides and processed silver grains when dry.

  1. 1. A solution used in floats tests to determine if a film is cellulose acetate or nitrate.
  2. 4. Damage caused by light is __________ and irreversible.
  3. 5. The deterioration of cellulose acetate is ___________; as the acetate film becomes more acidic, it further accelerates the deterioration process.
  4. 6. A type of insect that is attracted to photographic material.
  5. 7. Patented in 1839, this process produced light-fast images that relied on silver halide photochemistry.
  6. 10. The emulsion of cellulose acetate film becomes separated from the base in some areas when it has deteriorated.
  7. 11. A process that involves using chemistry to produce different coloured images. For example, the reaction of Ag with thiosulphate in an acid solution produces sulphur that reacts with the Ag image to create the brown Ag2S colour of sepia photographs.
  8. 12. A type of identification test for polyester-based film; place the film between two polarizing filters and it will display the shimmering rainbow-like patches on the film.
  9. 16. A type of destructive testing that can be done on film negatives in order to determine if it is nitrate or acetate based film.
