Detailed explanation-1: -Stray radiation reaching the film either as a result of background fog, or owing to scatter from within the patient, produces unwanted film density (blackening), and thus reduces radiographic contrast.
Detailed explanation-2: -A high-kilovoltage setting will produce a darker image with many shades of gray.
Detailed explanation-3: -The three main components of any x-ray exposure are kVp, mA, and time. * kVp: the power and strength of the x-ray beam (quality of the x-rays). * mAs: the number of x-ray photons produced by the x-ray tube at the setting selected (quantity of x-rays). * time: how long the exposure lasts.
Detailed explanation-4: -Films exhibiting a yellow or yellow-brownish color are typically the result of poor processing conditions. The most common cause of this discoloration would be poor chemical quality or exhausted chemistry.
