EX1; Film Processing and Darkroom

Question 1

What are the 5 steps to manual film processing

Answer 1

development
rinse
fixation
wash
dry

Question 2

What material are the tanks for manual processing

Answer 2

stainless steel

Question 3

This serves as a rinse and maintain required temp

Answer 3

water

Question 4

What are three advantages to manual processing

Answer 4

cheap
lasts “forever”
easy to maintain

Question 5

What are four disadvantages to manual processing

Answer 5

temperature is not regulated
need time-temp chart
drying cabinet
developer contamination

Question 6

What are two advantages about rapid processing

Answer 6

no dilution necessary

instant; develops in 15 sec, fixes for 15 sec at room temperature

Question 7

what are three disadvantages to rapid processing involving the process of making it

Answer 7

solutions only last about 2 days before oxidizing
usually used with chair side darkroom
sensitive to variables (time)

Question 8

what are some disadvantages to rapid processing involving viewing the image

Answer 8

lower contrast
may discolor over time
need to be fixed and washed after viewing

Question 9

What are the four steps to automated processing

Answer 9

development
fixation
wash
dry

Question 10

How long does it take for automated processing

Answer 10

4-6 minutes/cycle

Question 11

Automated processing delivers consistent what

Answer 11

density and contrast; less human variables

Question 12

This eliminates the need for a darkroom with automated processing

Answer 12

day light loader

Question 13

This is added to automated processing to minimize the swelling of the emulsion so the films can be transported by the rollers uniformly

Answer 13

sulfate

Question 14

What would occur if you placed the manual processing developer solution in an automated processer

Answer 14

film emulsion will most likely stick to the rollers and damage the radiographic image

Question 15

True or False

The automated processor is continuous feed and can process all sizes of film

Answer 15

False; it can only process 0, 1, 2, and 4

Question 16

How can an automatic processor have continuous automatic replenishment

Answer 16

attachment to sink;

also allows larger films to be processed

Question 17

True or False

There are many different automated processor systems

Answer 17

True

Question 18

What are the different types of dark room entry designs

Answer 18

maze-type
double door
spring mounted door
revolving door

Question 19

This filter is used as a safelight

Answer 19

GBX2 (ruby red) filter

Question 20

This filter is used as a safelight but is unsafe for panoramic radiographs

Answer 20

ML-2 (orange)

Question 21

What three factors affect a safe light

Answer 21

color
wattage (7.5 to 15)
distance

Question 22

Where is the best location for the safe light

Answer 22

4 feet from the surface of where the films will be handled

best place = right of fixing tank

Question 23

How would you test for safeness in a dark room

Answer 23

place a coin on an unexposed and exposed film - 2 minutes
process
and if outline of coin is present, the safelight is broken
