Do you often use filters in photography?

Adding a mirror is like covering a layer of yarn. If you add it blindly, the effect will definitely be bad! However, the clever use of filters is also an art. For example, in black-and-white photography, color filters are needed to adjust the contrast, such as defogging mirrors in foggy days, medium gray mirrors in running water, gradient mirrors for highlights, polarizers for blue sky and white clouds, and so on. Many methods that can be planned before shooting are often not added at all in the later stage.
