DANB RHS PRACTICE EXAM QUESTIONS FOR
GUARANTEED PASS 2025/2026
What is the processing time difference between automatic processing and manual
processing?
Why? - correct-answer-With automatic processing, the total processing time is
between 1.5-5 minutes
-Using rollers that guide the film through the processor and wring out excess
solutions
-increasing the temperature and concentrations of reagents
What is the development process of processing manual film - correct-answer-Lock
the darkroom/label hangers
Agitate developer and fixing solutions with individual stirrers and chemicals, re fill
if necessary
Check temperature of water bath - 70 degrees
White light is eliminated, activate safelight
Using gloves, open film packet
,2|Page
Remove gloves, insert films into hangers
Adjust timer to development time - 5 min
Lower film into developer sol. set timer
What is the process for manual film AFTER development? AKA fixation process -
correct-answer-After development period is complete...
Film is transferred to the rinsing tank (water bath) and swirled for .5 minutes to
remove the developer
Film is put into fixer solution for 10 minutes.
What is the process after the fixation process? - correct-answer-After fixation...
Normal lighting turned on/safelight turned off
Film is washed in bath for 15-20 min
Dried on rack, then mounted.

What is the effective temperature range of manual processing of x-rays? - correct-
answer-60-75 degrees, suggested temp. 70
What happens when the temperature for manual processing is higher than the
suggested temperature? - correct-answer-The image becomes foggy (excessive
and rapid development)
What is a safelight? - correct-answer-a low intensity light in the red-orange
spectrum
What is the purpose of fixation solution? - correct-answer-To remove unexposed
silver halide crystals
In the fixer solution, what are the fixation agents?
What does it do? - correct-answer-Thiosulfates coupled to either ammonium or
sodium
Remove the unexposed silver bromide crystals from the emulsion gel?
, 4|Page
In the fixer solution, what medium terminates the development by neutralization?
- correct-answer-Acetic or sulfuric acid
In the fixer solution, what are examples of chemical hardeners that harden the
gelatin? - correct-answer-Aluminum sulfide, potassium aluminum sulfate
what is the primary purpose of the developer solution? - correct-answer-Reduce
the silver halide crystal generated during the radiation into the black metallic
silver
In the developer solution, what is the reducing agents?
What is it's purpose? - correct-answer-Metol
Induce grey tones and hydroquinone
In the developer solution, what is the activator ?
What is it's purpose? - correct-answer-Sodium carbonate
Provides alkaline pH and softens the emulsion
In the developer solution, what prevents the non-exposed silver bromide crystals
from developing? - correct-answer-Restrainer made of potassium bromide
