How to use camera fogging lens

The fog filter is a type of camera filter. It is a commonly used filter for natural scenery photography. It is also widely used in advertising photography and portrait photography. It can create a foggy effect in the work and increase the atmosphere. Sense of perspective. Different models are divided into different models according to the strength of the diffusion effect of the lenses. Those with strong effects can produce a dense fog effect, while those with weak effects can produce a thin mist effect. In addition, the amount of exposure will also affect the intensity of fog.

Guidelines for using various filters for SLR cameras?

Red lens (R):

Absorb blue light, which can produce a romantic sky effect or similar during daytime shooting It has the effect of moonlight night and has the function of absorbing ultraviolet rays. When shooting, it is generally necessary to increase the exposure by three levels. The specific requirements need to be flexibly controlled according to the shooting requirements and the depth of the filter. This mirror is generally used for black and white photos, but can also be used for color photography. The functions of other color filters are basically similar.

UV (ultraviolet) mirror:

This mirror can basically eliminate the impact of ultraviolet rays and stray light on film sensitivity, and at the same time protect the lens. Photography is even more necessary in plateau areas.

Blue mirror (B):

Used for black and white photography. The mirror passes cyan, blue, and violet light and absorbs red, orange, yellow and other colors. The wavelength passes in the range of about 400-500nm, and the exposure needs to be increased by about 2 levels (flexibly controlled according to the depth of the color mirror).

Skylight mirror:

Skylight mirror presents a very light magenta color. In addition to absorbing ultraviolet light, it can also absorb part of blue light and green light, so it plays a role in the color of the final picture. A certain balancing effect

Reflecting mirror:

The mirror is a rectangular reflector with regular reflection (mirror surface vacuum silver-plated), with a pair of coaxial knobs at both ends (adjustment lens angle).

Gradient filter:

Gradient filter is one of the most important filters for photographic art creation. It can be divided into gradient color filter and gradient diffusion. Mirror, in terms of gradient form, can be divided into soft gradient and hard gradient. "Soft" means a larger transition range, and conversely, that is, a smaller transition range, both of which need to be selected according to the creative characteristics.

Fog mirror:

This mirror is a commonly used filter for natural scenery photography. It is also widely used in advertising photography and portrait photography. It can produce a foggy effect in the work. Increase the sense of atmospheric perspective.

Polarizer (Polarizer):

Referred to as PL filter, this filter can effectively reduce or eliminate reflections on non-metallic surfaces. Polarizers can be used in both black and white and color photography. Adding a polarizer when taking color photography can darken the color of the sky while still maintaining the other original colors of the scene.
