[Punch R] Novice photographers must see 5 camera filters!

Let me share the camera filter with you today. This filter is not another filter. The filter we share today is a kind of camera accessories.

Function of UV mirror

UV mirror, also known as ultraviolet filter, refers to a filter used in digital cameras. It is a solid lens, which can be used with camera lens to protect the lens and improve the image quality.

In the film age, UV mirrors were mainly used to filter ultraviolet rays.

In the digital age, the function of UV mirror has become to protect the lens.

If we take something we are familiar with as an example, adding a UV mirror to the lens is like pasting a film on a mobile phone.

Improve image quality

The main function of UV mirror is to absorb ultraviolet rays with wavelength below 400 nm. Suitable for shooting in seaside, mountains, snowfields and open areas, which can weaken the blue tone caused by ultraviolet rays. It helps to improve the clarity and color reproduction.

Protective lens

UV mirror does not have many additional functions, and it is often used as a protective mirror to prevent dust and stains from entering the lens and prevent collisions and scratches.

The role of CPL polarizer

CPL polarizer, also called polarizer, can filter reflected light and increase imaging contrast. The main function is to eliminate the reflection of glass or water surface, increase the saturation of color and deepen the color of the sky.

For scenes with strong reflection, sometimes we need to eliminate the influence of glass water surface.

CPL can restore color and eliminate reflective effect, and is often used in landscape photography.

The role of neodymium reduction mirror

Neodymium mirror is a dimming filter. Traditionally, it is called medium gray density mirror and neutral gray mirror, and the lens has gray tone. It is a filter that can reduce the amount of light entering through the gray transition layer.

In the case of overexposure by using the minimum aperture and the fastest shutter, the exposure value is reduced by adding an nd mirror in front of the lens (reducing the amount of light entering).

The characteristics of this filter are: the drag reduction ability of colored light (light) with different wavelengths is equal and uniform; It will not have any influence on the color of the subject, so it can truly reproduce the color contrast and brightness difference of the scene.

The role of starlight mirror

Starlight mirror refers to a camera filter, which is divided into 2 lines, 4 lines, 6 lines, 8 lines and 16 lines. Can produce the diffraction effect of light, forming a radiant effect, mostly used in artistic photography, suitable for landscapes and portraits. It can simulate the effect of star awn, and is mostly suitable for landscapes and portraits.

The function of black soft filter

Black soft has three specifications: 1/2, 1/4 and 1/8. The larger the value, the better the soft light effect. Black soft light filter has been very commonly used in business scenes of portrait shooting, which can make the picture more delicate, soft and beautiful.

Portraits are commonly used and can produce beautiful soft light effects.
