Detailed explanation-1: -The fixing solution creates “light” areas on a developed film. Therefore, contamination with the fixer solution will cause white spots. Insufficient washing or exhausted solution can create brown and yellow stains.
Detailed explanation-2: -White Spots: These are also called as fixer spots on the film which is caused due to droplets of fixing solution coming in contact with an exposed film before it is developed.
Detailed explanation-3: -Fixer spots result from fixer solution being splashed onto the unprocessed film. A cone-cut results from failure to correctly align the PID with the film. Exhausted processing solutions and insufficient washing can all contribute to a yellow-brown stain on the film.
Detailed explanation-4: -What do white spots on a film after processing mean? Expense of the machine.
Detailed explanation-5: -Structures that are dense (such as bone) will block most of the x-ray waves, and will appear white. Metal and contrast media (special dye used to highlight areas of the body) will also appear white. Structures containing air will be black, and muscle, fat, and fluid will appear as shades of gray.
