The original camera camera negative OCN is the type of film that is actually used during the filming process. Before it is exposed, it is called raw stock. This film type basically captures the original image so that it can be stored, modified or used at a future point. If the OCN is older, it may also need to be repaired before it can be used or transferred to a new medium. To prevent wear and tear, modern filmmakers will normally transfer copies of the film immediately so that the original camera negative is used as little as possible.
Each roll varies in sized depending on the film gauge, the roll and other factors. When using 16 mm, 400 foot rolls are the most common. Meanwhile, 1,000 foot rolls are the norm for 35 mm film. Depending…
This allows the safety positive to be used as a backup rather than risking the safety of the negative. Answer prints are made, which allow release prints to be created. Since the original camera negative is vital for storing the film, it is used for the least number of activities possible. Each time it goes through a laboratory, there is a risk that it will be degraded, scratched or damaged. Due to this, the original camera negative is generally the last resort and is only used when the other copies have been lost, damaged or compromised. Prior to 1969, 35 mm prints were made from the OCN. This means that older films often have more damage and need professional…
A climate-controlled room or vault is generally the first step toward preserving the film. In addition, the film needs to be repaired and copied by a company like Rising Fall. Color correction and other techniques can be used to restore the film to its original quality. With the original film stored safely away, the new copy can be watching without worrying about potentially damaging it.
During this process, there are a few things that can make restoration more difficult. Often, curling occurs because of humidity or light exposure. There may be tears on the print, damaged perforations or missing frames. For older movies, these problems are especially common. Digitally, damaged frames can be recreated based on the frames that they are next to. This technique is extremely effective as long as there are enough frames available to predict the image that would have existed in the damaged frame.
Digitally Restoring the Film
The first step is to inspect the film for any signs of wear and tear. Before it can be transferred to a telecine any dust, dirt or scratches must be repaired. If the color has changed or faded, color correction may be needed. Shrinkage, missing scenes or sound problems must be edited before it can be…
