Black-and-white camera film, in the old days of film photography, was very sensitive to blue light but not to red light. Blue skies would often show very little detail, because the film couldn’t record all that it was seeing. To compensate, photographers would put a red filter on the lens, darkening the sky enough that the film could record its fluffy clouds.

This paragraph best supports the statement that
