What effect does smoking have on photographic film?

Smoking produces light and fogs the film due to the particulate matter and chemicals released in cigarette smoke. When smoke settles on the film emulsion, it creates a hazy effect that can obscure the details of the radiographic image. The particles in the smoke scatter light and can reduce the contrast of the image, making it difficult to achieve clear and defined results. This fogging effect can significantly degrade the quality of radiographic images, affecting the ability to accurately assess the material being examined. Thus, understanding the impact of smoking on photographic film is crucial for maintaining the integrity of radiographic processes.
