If you mix light sources with different color temperatures, what issue arises and how can you address it?

• A. Mixing different color temperatures causes color casts; address by setting WB to neutral or balance.
• B. Mixing temperatures has no effect on color.
• C. It only affects highlight detail.
• D. It changes exposure level.

Answer: (A)

When you mix light sources with different color temperatures, color casts appear in the image because each light adds its own tint—warm (yellow/orange) from some sources and cool (blue) from others. The camera’s white balance is designed to neutralize that tint, so if the lighting isn’t at the same temperature, whites and other colors shift accordingly. The best fix is to set white balance to a neutral or balanced setting (or use a Kelvin value) so the camera correctly compensates for the mixed lighting. If you can’t get it right in camera, shooting in RAW lets you tweak white balance later. You could also even out the scene by using lights with the same color temperature or by adding gels to bring all sources to a common temperature. The key idea is that the issue is color-related, not about highlights or exposure.
