What should I pay attention to when taking black-and-white photos with film cameras?

First, we should pay attention to remove the color information in our mind and only see the brightness, otherwise some subjects with prominent colors may be submerged in an environment with similar brightness and cannot stand out.

Second, we should pay attention to the rational use of filters.

Third, we should pay attention to the above two points, especially the first point.

Don't you know there is a filter for taking black and white photos downstairs? I suggest you take a look at the relevant photography textbooks, especially the chapters on black and white photography. Color filter (excluding effect mirror) mainly plays the role of highlighting the subject and changing the contrast in black and white photography. Here are two examples. For example, when you shoot blue sky and white clouds, you may want more contrast. What should I do without a filter? Of course not. At this time, the yellow filter can be used to reduce the brightness of the blue sky to improve the contrast. For example, when red flowers are photographed with green leaves, if the brightness of the flowers is close to that of the green leaves, the flowers will be lost in the green leaves. At this time, you can use the red filter to reduce the brightness of the green leaves to improve the contrast and make the flowers stand out. Please read the relevant teaching materials for specific principles.

As for the polarizer, it can also be used in black and white photography to change the contrast of the picture. Therefore, it is suggested that the master downstairs must remember one sentence-no investigation, no right to speak.
