Certified Professional Photographer (CPP) Practice Exam

What color temperature is indicated by a typical daylight scenario with a clear sun overhead?

1. 5,000-6,500 K

2. 9,000-10,000 K

3. 6,500-8,000 K

4. 4,000-5,000 K

The correct answer is: 5,000-6,500 K

In a typical daylight scenario with a clear sun overhead, the color temperature ranges between 5,000 and 6,500 Kelvin. This range represents the quality of light provided by the sun when it is positioned directly overhead, emitting a neutral to slightly bluish-white light. Photographers often refer to this range as "daylight" because it is the standard reference point for white balance in photography. The light during this condition has a balanced spectrum across the visible wavelengths, closely resembling white light, which is why it's important for photographers to use this reference when setting their cameras for accurate color representation. This range is also vital when editing photos, as understanding color temperature helps in correcting or enhancing the warmth or coolness in photographs to achieve the desired effect. The other options indicate color temperatures that are outside the typical daylight range. The higher values suggest scenarios in different lighting conditions, like shade or overcast environments, where the light tends to appear cooler or bluer.
