ASSIGNMENT  8 Textbook  Assignment: "Image  Processing  and  Control." Pages   10-1 through 10-30. 8-1. 8-2. 8-3. Learning Objective: Recognize functions   of  the  various  solutions used  to  process  light-sensitive materials. What  process  is  most  commonly used  for  film  development? 1. Physical 2. Chemical 3. Intensification 4. Latent  conversion When  performed  correctly,  the chemical  development  process reduces  exposed  silver  halides to  what  composition? 1. Black  metallic  silver 2. Soluble-silver  salt 3. Dye-image  salt 4. Gray-tone  dye All  silver  halides,  both  exposed and unexposed,   can be reduced to metallic  silver  in  the  development process. 1. True 2. False 8-4. What  term  describes  the  amount  of silver in a film emulsion that has been  reduced  to  black  metallic silver? 1. Light struck 2. Rate  phenomenon 3. Density 4. Primary  silver 8-5. What  is  the  most  important ingredient  in  a  developing solution? 1. Preservative 2. Accelerator 3. Restrainer 4. Reducing  agent 8-6. What is the purpose of the preservative  in  a  developing solution? 1. It makes the image permanent 2. It  retards  oxidation 3. It  prevents  the  formation of poisonous gas 4. It  prevents  the  reducing  agent from  attacking  the  unexposed silver  halides 8-7. Which  of  the  following  chemicals may  be  used  as  a  preservative? 1. Hydroquinone 2. Metol 3. Sodium  hydroxide 4. Sodium  sulfite 8-8. What  ingredient  in  a  developing solution  makes  it  alkaline? 1. Reducing  agent 2. Accelerator 3. Preservative 4. Restrainer 8-9. What  two  functions  does  the accelerator  in  a  developing agent  serve? 1. It  constricts  the  emulsion and  prevents   aerial  oxidation 2. It  constricts  the  emulsion and increases the rate of development 3. It swells the emulsion and absorbs  the  halide  elements freed from the silver 4. It swells the emulsion and retards the rate of development 8-10. A developer with which of the following  pH  values  will  most likely produce an image with a finer  grain? 1. 1.5 2. 5.5 3. 8.5 4. 11.0 57
