UV Filter

• Function: block UV light, protect lens from scratch, dropping, water and dirt.
• Performance requirements: high transmittance over 98%, HD optical glass with AR (anti-reflection) coating, without flare.
• Application: open-air, such as Seaside, desert, plateau, mountainous area, snowfield, etc.

CPL Filter

• Function:
  • Eliminate reflections on non-metallic surfaces (such as water, glass, and leaves);
  • Enhance color saturation (e.g., make the blue sky bluer, the vegetation greener);
  • Reduce screen glare and enhance contrast.
• Performance requirements: high transmittance over 98%, HD optical glass with AR (anti-reflection) coating, without flare.
• Application: Landscape photography (reflection on lake surface, blue sky and white clouds), still life photography (glassware), portrait photography (eliminating skin shine).
• Notice: It will reduce the light intake by about 1-2 stops, requiring an increase in ISO or a slower shutter speed.

ND Filter /VND

• Function: Reduce the amount of light entering the lens, allowing the use of a large aperture or slow shutter speed under strong light conditions.
• Typical effects: shooting flowing water, moving clouds, and blurring crowds (dynamic blur).
• Usage scenario: Long exposure during the day (such as waterfalls, train tracks, sea spray), video shooting (requires maintaining a fixed shutter speed).
• Advantages: Multiple gear options (ND2/ND4/ND8, etc.), allowing flexible control over dimming intensity; does not affect color balance.
• The difference between ND Filter and VND: ND stop is fixed, VND stops adjustable.

GND

• Function: Balance the light ratio in high-contrast scenes (such as scenes with a large brightness difference between the sky and the ground); By gradually darkening the bright areas (such as the sky) through a gradient, while preserving the details of the dark areas (such as the ground scenery).
• Usage scenario: Landscape photography (sunrise/sunset, snow mountains, grasslands), urban architecture (sky and architecture have a large light ratio).
• Advantages: It is divided into hard gradient (with a clear boundary between light and dark) and soft gradient (with a natural transition), suitable for different scenarios;
• Notice: Precise alignment with the horizon is required, and misalignment is prone to occur during handheld shooting; digital post-production can partially replace it (such as HDR), but using it in the early stages is more efficient.

Night Filter

• Function: Filtering out yellow light of specific wavelengths and the color of the filter itself reduces the yellow light that interferes with night photography, making the night scene images cleaner.
• Application: Night photography

Color Filter

• Function:
  • Change the color tone of the picture (such as red, orange, blue, and other color filters);
  • Adjust the contrast of tones in black and white photography (such as using a yellow filter to darken the blue sky, or a red filter to highlight the red leaves);
  • Creative color adjustment to create a specific atmosphere (such as simulating a cool tone with a blue filter).
• Application: Black and white photography, creative portrait, stage lighting color correction, simulated film tone.
• Advantages: Direct color intervention, suitable for rapid creation in the early stage; precise tone control in black and white photography.
• Notice: The color needs to be precisely selected based on the lighting and subject matter, and excessive use may lead to color distortion; digital post-production color grading is more flexible, and the use of filters is gradually decreasing.

Starlight Filter

• Function:
  • Make point light sources (such as street lamps, the sun, and candlelight) produce a starburst effect (4/6/8 starbursts);
  • Enhance the dreamy feel and visual appeal of the image, especially suitable for night scenes or light spot scenes.
• Application: City nights-cape, festive lighting, stage photography, and backlight portrait (hair highlights turn into starbursts).
• Advantages: Unique effect, achieving starburst without post-production; low cost to achieve high visual impact.
• Notice: It is only effective for point light sources, and the star effect may be overexposed under strong light; it tends to appear "exaggerated" in non-essential scenes, so it should be used with caution.

Black Pro-Mist Filter

• Function:
  • Moderately soften the image, retain details and contrast, and reduce highlight glare;
  • Simulate the texture of film and enhance the "breathability" of the image, suitable for natural softening effects.
• Application: Portrait photography (commercial, fashion, softening skin while retaining three-dimensional sense); Cinematic narrative shots, outdoor shooting under strong light conditions (such as midday backlight).
• Advantages: Softens the natural look without reducing contrast, with rich details in the dark areas; compatible with various lighting conditions.

White Pro-Mist Filter

• Function:
  • Strong softening effect, with obvious halation and atomization in the highlight area;
  • Reduce contrast, enhance the transparency of the image, and create a dreamy atmosphere.
• Application: Portrait and wedding photography (backlighting to create hair halo); Fantasy themes, music videos, or romantic scenes (such as under misty or soft lighting).
• Advantages: Outstanding dreamy effect, suitable for creative expression; enhances the atmosphere of light in low-light environments.
• Notice: It may cause the image to appear grayish and prone to overexposure under strong light; excessive use can lead to loss of detail, so it is necessary to control the density (such as 1/4 stop).
