Detailed explanation-1: -Dark Spots: These are also called as developer spots which are caused due to droplets of fixing solution coming in contact with an exposed film before it is developed. White Area on Film: A portion of the film appears white when two films come in contact with each other during developing the film.
Detailed explanation-2: -Processed negatives are too dark Possible caused a faulty meter or incorrect readings. It could also be caused by the following development errors: Development time is too long. The developer is too warm.
Detailed explanation-3: -Page 3. What is Density and Contrast? Density is the overall darkness (blackness) of an image. Contrast is the difference in lightness and darkness between areas on a radiograph.
Detailed explanation-4: -Which of the technical errors in radiography will result in increased film density?-Focal-film distance is too short: Focal-film distance refers to the distance of the film relative to the X-ray source. As the film is moved closer to the source, density increases exponentially due to the inverse-square law.
