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: -Films that remain in the fixer too long appear light. Films that are underexposed appear light. Insufficient washing may cause some yellow-brown staining on the processed radiograph.
Detailed explanation-3: -Overexposure. Due to the high dynamic range in digital imaging, overexposure is slightly more challenging to identify. Overexposed images will have a distinct lack of quantum mottle while appearing ‘saturated’ or in extreme cases ‘burnt out’ whereby anatomy is completely obliterated from the radiograph.
Detailed explanation-4: -There are multiple causes of a dark image like excessive development, higher development temperature, inaccurate timer and also higher concentration of the developing solution can lead to Dark Image of the X-ray.
