As a Spherical Lens Manufacturer, I would like to share with you.
A filter is actually a piece of glass or plastic that is placed in front of the camera lens when shooting. There are many types of filters, which can basically be divided into several categories: some filters can be used to correct the appearance of a photo, some can be used to enhance a photo, and special effects filters can completely change the appearance of a photo.

In black and white photography, we use Filters to brighten or diminish the gray tones of a color on a black and white negative or photograph. In color photography, the use of filters is more complex because the color of the filter itself affects every color on the photo or slide. However, if used properly, filters can prove to be very effective in many color situations. First, consider a simple red filter. If you use it for color film, a strong red tint will appear on the slide or photo. If we prefer a red sky to a blue one, we can achieve our desire by using a red filter. This is called a "special effect".
However, when shooting in black and white with a red filter, the situation is completely different. Because there is only black and white, the "color" cannot be reflected in a black and white photo, but the black and white tone value on the photo can be changed. For example, using the same red filter for a black and white film, the gray tones of the blue sky will be darker than the sky without the filter. Thus, using a red filter can produce a black-and-white photograph of a dark gray sky and tumbling white clouds. The result may be a beautiful and natural black and white photo.
We may not understand the mystery of this, but don't worry. In this lesson, we'll discuss in detail the various filters used when shooting color or black-and-white film.
Let's look at another example: When shooting a bouquet of roses with black and white film, if we use the same red filter, we can vividly highlight the red roses from the background of green leaves. The result will be a very nice black-and-white photo, with the prominent bright red roses contrasting with the dark green foliage.
Therefore, the right choice of filters is an important creative tool we can use. Also our company has Laser Filters Lens for sale, please feel free to contact us.
