The camera has several special lenses

1 Red mirror (R): It can block the blue-green light and darken the sky, leaves and other parts with blue. The red mirror is used in black and white photography to highlight the white clouds and darken the sky. It can also absorb ultraviolet rays. When photographing blue drawings and documents under artificial light, good contrast can be obtained by using a red mirror. This mirror is also commonly used in infrared photography.

2 Yellow mirror (Y): It is applicable to the adjustment of black and white contrast, and the effect of shooting white clouds in the sky is outstanding. The color depth of the mirror is divided into several numbers, which can be selected according to your own needs. The light yellow lens is also suitable for taking color photos.

3 Blue mirror (B): It passes through the blue, cyan and purple colors, with blue passing the most, absorbing yellow, purple, orange, red and purple. It is mainly used for black and white photography. Two exposures (medium and blue) should be added when using it- The mirror can absorb a small amount of ultraviolet light.

4 Leiden-80: The mirror is blue and can be used under artificial light. The color deviation of the photo can be adjusted. It is suitable for the use of daylight type film under light. There are three types: A, B and C.

5 Leiden-82: The mirror is light blue, which can be used for color temperature compensation. In the morning or evening, outdoor photography can inhibit the phenomenon of reddening, so as to achieve realistic color. According to the depth, it can also be divided into A, B and C.

6 Leiden-85: The mirror is used to calibrate the color deviation caused by using light type film in daylight, which is divided into three types: A, B and C.

7 Starlight mirror: This mirror is a straight line starlight (4 lines), a cross starlight (6 lines), a snow line starlight (6 lines), and a meter line starlight (8 lines). It can be used to take pictures of night scenes, solar rays, and artificial point light sources, and can emit various flash effects. It is more ideal to shoot women wearing jewelry, which is suitable for shooting stage lighting, etc.

8 Rainbow mirror: This lens is a circular rainbow, a rainbow, a 4-wire rainbow, an 8-wire rainbow, a 12 wire rainbow, an 18 wire rainbow, a 24 wire rainbow, a 36 wire rainbow, etc. When shooting, each light point can show seven colors of rainbow light, which is rich in color, strong in contrast, and produces colorful strange effects. It can fully express the imagination and is most suitable for color photography.

9 Polarizer (PL): It can eliminate the reflection of the object surface. Outdoor photography can make the blue sky bluer, the image more bright, and the color saturation. It can be used to shoot black and white and color films. It can also produce an infrared effect when used with a medium red lens. When shooting shop window displays, if polarizers are not used, the photos taken will not be clear because of the serious interference of the reflective light on the window glass surface; With the polarizer, the reflection of the window glass surface is eliminated, and the picture is clear.
