Which type of film is optimized for 3200K lighting?

1. Fluorescent

2. Tungsten

3. Daylight

4. High-speed

The correct answer is: Tungsten

The type of film that is optimized for 3200K lighting is tungsten film. This film is designed specifically to render colors accurately under incandescent lighting conditions, which typically have a color temperature around 3200K. Tungsten film achieves this by using a dye formulation that compensates for the warm tone of the light, ensuring that the colors in the resulting photographs appear true to life. On the other hand, fluorescent film is engineered to work under fluorescent lighting, which has a different color temperature and spectral output. Daylight film is optimized for natural light conditions, usually around 5500K, making it less effective under tungsten lighting. High-speed film, while capable of capturing images with less light, does not have any inherent optimization for a specific type of lighting, focusing more on sensitivity rather than color balance. Therefore, tungsten film is distinctively suited for 3200K lighting situations.
