How does the use of a #8 yellow filter affect the sky's color?

1. It makes it appear brighter.

2. It makes it appear darker.

3. It enhances its vibrancy.

4. It eliminates color entirely.

The correct answer is: It makes it appear darker.

Using a #8 yellow filter primarily affects color contrast and brightness in photography. A yellow filter works by allowing more yellow light to reach the film or sensor while absorbing some of the blue light. This action intensifies the contrast between the sky and clouds, leading to a deeper, darker blue sky while also making the clouds stand out more distinctly. The filter's ability to darken the blue sky is particularly advantageous for landscape photography as it enhances the overall composition and depth of the image, making it visually striking. This effect is especially noticeable in black-and-white photography where it can help create a more dynamic image with a pronounced tonal range. While it may enhance certain aspects of vibrancy, the most prominent and observable effect of a yellow filter is its tendency to darken the blue tones in the sky. Therefore, the understanding that it makes the sky appear darker is crucial when considering its application in photography.
