Detailed explanation-1: -Underexposed receptors result in images that are too light or low in density. Light images can also be caused by an increase in the source-object distance, or not placing the tubehead close enough to the patient’s face during exposure.
Detailed explanation-2: -Improper safelighting, Darkroom light leaks, Improper film storage, Outdated films, Contaminated processing solutions, High developing temps.
