Film Negative Processing Workflow.
1. Exposing the Film: The first step in the film negative processing workflow is to expose the film to light. This is done by running the film through a camera, which opens and closes the shutter to allow light to reach the film. The amount of light that reaches the film determines the exposure, which will affect the density of the negative.
2. Developing the Film: Once the film has been exposed, it is developed in a chemical solution. This solution converts the exposed silver halide crystals on the film
into metallic silver, which forms the image. The developing process is carefully controlled to ensure that the image is properly formed and has the desired density.
3. Stop Bath: After the film has been developed, it is
rinsed in a stop bath to stop the development process. The stop bath is a weak acid solution that neutralizes the developer and prevents it from continuing to react with the film.
4. Fixing the Film: The next step is to fix the film. This is done by immersing the film in a solution of sodium thiosulfate, which removes the unexposed silver halide crystals from the film. The fixing process is essential to prevent the film from darkening over time.
5. Washing the Film: After the film has been fixed, it is washed in water to remove any residual chemicals. The washing process is carefully controlled to ensure that the film is properly washed and does not contain any contaminants.
6. Drying the Film: The final step in the film negative processing workflow is to dry the film. This is done by hanging the film up in a clean, dust-free environment. The film is allowed to dry completely before it is stored.

1. 曝光胶片，电影胶片处理的第一步是将胶片曝光于光线。

这是通过将胶片穿过相机来完成的，相机打开并关闭快门以使光线到达胶片。

到达胶片的曝光量决定了曝光度，曝光度将影响负片的密度。

2. 冲洗胶片，胶片曝光后，在化学溶液中进行冲洗。

此溶液将胶片上的曝光卤化银晶体转化为金属银，形成图像。

冲洗过程经过仔细控制，以确保图像形成正确且具有所需的密度。

3. 终止浴，胶片冲洗后，在终止浴中冲洗以停止冲洗过程。

终止浴是一种弱酸溶液，可以中和显影剂并防止其继续与胶片反应。

4. 定影胶片，下一步是定影胶片。

这是通过将胶片浸入硫代硫酸钠溶液中来完成的，该溶液从胶片中去除未曝光的卤化银晶体。

定影过程对于防止胶片随着时间的推移而变暗至关重要。

5. 清洗胶片，胶片定影后，在水中清洗以去除任何残留的化学物质。

清洗过程经过仔细控制，以确保胶片得到正确清洗且不含任
何污染物。

6. 干燥胶片，电影胶片处理流程的最后一步是干燥胶片。

这是通过将胶片悬挂在干净无尘的环境中完成的。

胶片在储存前应完全干燥。
