An 80A tungsten CC filter adjusts the color temperature from which value to daylight?

1. 3,200°K

2. 3,500°K

3. 2,800°K

4. 4,000°K

The correct answer is: 3,200°K

When discussing the effect of an 80A tungsten CC filter, it's important to understand how color temperature interacts with various lighting conditions. An 80A filter is specifically designed to convert tungsten light, generally around 3,200°K, to a daylight color balance, which is typically around 5,600°K. This means that the starting point for the tungsten color temperature, when using this filter, is indeed 3,200°K. The filter effectively shifts the color representation from the warmer tones of tungsten light towards the cooler tones of daylight. By applying the 80A filter, photographers working under tungsten illumination can accurately capture images that match the daylight spectrum, resulting in more natural color representation in their photographs. The other temperature values listed do not correspond to the typical starting point for tungsten lighting. This makes option A the most accurate choice in relation to how the 80A filter alters the color temperature.
