What is the error?
|
Processing Error
Underdeveloped film appears light. Inadequate development time. Developer solution too cool Inaccurate timer or thermometer Depleted or contaminated developer solution To fix? Check development time and temperature. Replace faulty timer & thermometer Replenish developer with fresh solutions as needed. |
|
What is the error?
|
Processing Error
Overdeveloped film appears too dark. Excessive developing time Developer solution too hot Inaccurate timer or thermometer Concentrated developer solution To fix? Check development time & temperature. Replace faulty timer & thermometer Replenish developer with fresh solutions |
|
What is the error?
|
Processing and FH Error:
Reticulation of Emulsion Sudden temperature change between developer & water bath. To fix? Check temperature of processing solutions and water bath. Avoid drastic temperature changes |
|
What is the error?
|
Developer spots appear dark or black.
Developer comes in contact with film before processing To fix? Use a clean work area. |
|
What is the error?
|
Fixer spots appear as white or light spots
The fixer comes in contact with film before processing To fix? Use a clean work area. |
|
What is the error?
|
Yellow brown color results in exhausted developer or fixer.
Insufficient fixation time Insufficient rinsing Artifact: Fingerprint To fix? Replenish chemicals with fresh solutions Use adequate fixation time. Rinse for a minimum of 20 minutes. Hold film by sides. |
|
What is the error?
|
FH Error:
Developer cutoff has a straight white border Underdeveloped portion of film due to low level of developer. To fix: Check developer level before processing & add solution if necessary. |
|
What is the error?
|
FH Error:
Fixer cutoff – Straight black border on a film Unfixed portion of film due to low level of fixer. To fix? Check fixer level before proceeding & add solution if needed. |
|
What is the error?
|
FH Error:
Overlapped films have white or dark areas that appear on film when overlapped. Two films contacting each other during processing. To fix? Separate films so that no contact takes place during processing. |
|
What is the error?
|
FH Error:
Air bubbles appear as tiny white spots. Air is trapped on the film surfaces after being placing in the processing solution. To fix? Gently agitate film racks when film is in processing solution. |
|
What is the error?
|
FH Error:
Fingernail Artifact appears as a black crescent-shaped mark. Also, Underdeveloped. Film emulsion damaged by operator’s fingernail during rough handling To fix? Gently handle films & hold them on edges only. Check development times, temperature |
|
What is the error?
|
FH Error:
Fingerprint Artifact appears as a black fingerprint. Film touched by fingers that are contaminated with fluoride or developer. To fix? Wash & dry hands thoroughly before processing films. |
|
What is the error?
|
FH Error:
Static Electricity appears as thin, black, branching lines Occurs when a film packet is opened quickly or before the radiographer touches a conductive object. To Fix? Open packet slowly and touch a conductive object before opening films. |
|
What is the error?
|
FH Error:
Scratched film has white lines on it. Soft emulsion is removed from the film by a sharp object. To fix? Use care when handling films and film racks. |
|
What is the error?
|
FH Error:
Light Leak – exposed area appears black. Accidental exposure of film to white light. To fix? Examine film packets for defects before using. Never unwrap films in the presence of white light. |
|
What is the error?
|
FH Error:
Fogged film is gray; lack of detail or contrast. Improper safelighting Light leaks in darkroom Outdated films Improper film storage Contaminated solutions Developer solution too hot To fix? Check filter & bulb wattage of safelight. Check darkroom for light leaks. Check expiration date on film packets. Store films in a cool, dry protected area Avoid contaminated solutions by covering tanks after each use. Check temperature of the developer. |
