How is restoration subdivided by complexity level?
The degree of complexity depends on many factors. The most important ones are the severity and nature of image damages, as well as the number of important objects on the picture. The severity of damage can be roughly explained as the relation between the damaged area and the total image surface. The nature of damages is determined by predominant flaws. For example, elimination of cracks and scratches doesn’t take near as much time and effort as restoration of massive emulsion destruction. Restoration of lost image fragments is even more complicated. Also, elimination of a scratch across the face of a person on the picture is obviously more complex than getting rid of a scratch down the building wall. The same is true for a scratch on an eye versus a scratch on a cheek. The largest work load usually lays on restoration of people’s bodies and especially their faces. Therefore, the work load is usually proportionate to the number of people in the picture.
