Today I would like to share with you camera filters. This "filter" is not that "filter". The filter we share today is a type of camera accessory.

The role of UV mirror

UV mirror, also known as ultraviolet filter (UltraViolet), refers to a filter used by digital cameras and is an entity used with the camera lens Lenses protect the lens and improve picture quality.

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

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

If we use an analogy with something we are familiar with, adding a UV lens to a lens is like applying a film to a mobile phone.

Improve image quality

The main function of the UV lens is to absorb ultraviolet rays with wavelengths below 400 nanometers. It is suitable for shooting in environments such as seaside, mountains, snowfields and open areas. , can reduce the blue tint caused by ultraviolet rays. Helps improve clarity and color reproduction.

Protecting the lens

UV mirrors do not have many additional functions and are often used as protective lenses to prevent dust and stains from entering the lens and to 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 reflections on glass or water, increase color saturation, and deepen the color of the sky.

For scenes with strong reflections, sometimes we also need to eliminate the impact of glass water surfaces, etc.

CPL can restore colors and eliminate the effect of reflections, which is commonly used in landscape photography

The role of ND filter

ND filter is a kind of light reduction filter. It is customary to call it a neutral density lens or a neutral gray scale lens. The lens has a gray tone and is a filter that uses a gray transition layer to reduce the amount of light entering.

When using the smallest aperture and fastest shutter speed and still overexposing, add an ND filter in front of the lens to lower the exposure value (reduce the amount of light entering the lens).

The characteristics of this kind of filter are: the ability to reduce the resistance of various colored lights (lights) of different wavelengths is equal and uniform; it will not have any impact 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 type of camera filter, which is divided into 2-line, 4-line, 6-line, 8-line, 16-line and other types. It can produce light diffraction to create a radiant effect. It is mostly used in art photography and is suitable for landscapes and portraits. The effect that can simulate starbursts is mostly suitable for landscapes and portraits.

The function of the black soft filter

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

Commonly used for portraits, it can create a beautiful soft light effect
