Xiaoai photography
Many people say it is blue because it can make the sky bluer.
But after looking up a lot of information, I found that I used a yellow filter after comparing the pictures.
In fact, different color filters can achieve different effects. But as an examination question, you should still choose B.
Analysis: Anyone who likes photography knows that a yellow filter should be installed when shooting the blue sky, so as to shoot the clouds in the sky. If a blue filter is installed, the sky will be blue and clouds will not be photographed and recorded. Such a photographic work is meaningless and certainly not a work.
Outdoor photography activities are mostly inseparable from the performance of the sky. Blue sky and white clouds or brilliant clouds all over the sky often add luster to an ordinary landscape photo; People also like to use "white clouds floating in the blue sky" as the background when taking commemorative photos every day.
In order to show the blue sky and white clouds, you can add a yellow filter, which can absorb the light of the blue sky and white clouds, but it can prevent the blue sky from absorbing the blue-violet light, showing a deep gray tone in the photo; The light absorption of white clouds is less, which makes the white clouds in the photo stand out in the dark gray sky.
You can also use a polarizing (vibrating) mirror to "shine in the clear sky after the rain": it plays a role in weakening the reflected light on the surface of the object. Exterior photography can make the sky bluer, with sharp contrast and saturated colors. Black-and-white and color photography are acceptable. You need to add 2 levels of exposure when shooting. It is a necessary filter for photographers.
