When shooting with black and white filters, will the different external environment have some influence on the shooting effect? What specific impact will it have? How to solve it?

In black-and-white photography, when using color filters to change the tone relationship of the picture, some external environment influences should be considered. First of all, let's talk about darkening the blue sky with yellow filter and red filter. It requires that the sky must be blue first, and cloudy days are invalid; It is also difficult to achieve in the case of backlight. The backlit sky is not blue and the brightness is super high. If it is completely darkened, the ground landscape will also be underexposed. Of course, you can use a flash to enhance the lighting of small scenes on the ground. In the previous article, I have talked about the photographic special effects brought by various color filters, such as "How does the yellow color filter darken the sky?" There is an analysis of the principle of yellow filtering dark sky.

In other black-and-white photography, such as shooting the ground scenery and the red flowers among the green leaves. Yellow filter or red filter can enhance the contrast of the subject and highlight the red flowers, but only if the saturation of the subject is high enough to show the contrast obviously, while black and white filter photography is not obvious in the landscape with low saturation.

The above information is referenced from the website of Mai Sha Photographic Equipment, hoping to help you understand this problem.
