Question

1. sep construct explanations suppose a movie director is filming on a set that should look like a hot desert. he wants the scene to appear warmer, such that the red and yellow tones are the most apparent. what color filters should he use? what color will the blue sky appear when he uses those filters, and why?

Explanation:

A red - yellow filter will allow red and yellow light to pass through while absorbing other colors. The blue sky reflects blue light. When a red - yellow filter is used, the blue light from the sky is absorbed. Since no light (or very little light if there are some impurities) is transmitted through the filter for the blue sky part, the blue sky will appear black.

Answer:

He should use red - yellow filters. The blue sky will appear black because the red - yellow filter absorbs the blue light reflected by the sky.
