Color correction filters are used to adjust the white balance of an image, which is the overall color temperature of the image. This can be done to correct for the color temperature of the light source, or to create a specific color effect.

A blue filter is used to correct for a warm light source, such as incandescent lighting. This is because blue is the complementary color of orange, which is the dominant color in warm light sources.

An orange filter is used to correct for a cool light source, such as daylight or fluorescent lighting. This is because orange is the complementary color of blue, which is the dominant color in cool light sources.

Warming filters add warmth to an image by reducing the amount of blue light and increasing the amount of red and yellow light. Cooling filters add coolness to an image by reducing the amount of red and yellow light and increasing the amount of blue light.

A yellow filter is used to create a sepia-toned effect by reducing the amount of blue light and increasing the amount of red and yellow light.

All of the above filters can be used to create a black-and-white effect by reducing the amount of color in an image. Blue filters reduce the amount of red and yellow light, green filters reduce the amount of red and blue light, and red filters reduce the amount of green and blue light.

Graduated neutral density filters have a gradual transition from dark to light, which allows them to be used to correct for uneven lighting. Solid neutral density filters have a uniform density, which means that they reduce the amount of light entering the lens by the same amount across the entire image.

Neutral density filters are used to reduce the amount of light entering the lens, which can be useful in situations where there is too much light, such as when shooting in bright sunlight.

Polarizing filters are used to reduce glare and reflections by blocking light waves that are vibrating in a certain direction. This can be useful for reducing glare from water, glass, and other reflective surfaces.

Ultraviolet filters are used to protect the lens from ultraviolet light, which can cause the image to appear hazy or blue-tinted.

Skylight filters are used to reduce the amount of blue light entering the lens, which can help to improve the color balance of an image.

Starburst filters are used to create a starburst effect by diffracting the light that enters the lens.

Soft-focus filters are used to create a soft-focus effect by reducing the sharpness of the image.

Vignette filters are used to create a vignette effect by darkening the edges of the image.

Cross-screen filters are used to create a cross-screen effect by diffracting the light that enters the lens.
