The main function is used for UV absorption wavelength at 400 nm under ultraviolet light, while the other visible / invisible light had no filtering effect. It was because the UV filter containing lead lenses, UV and other so the same size and thickness of the lens compared to some. At the same time, UV coating surface lens can avoid direct contact with the external environment, play a protective role.
Application of UV in the sea, mountains, snow and open environment such as shooting, can weaken the blue tone caused by ultraviolet rays. At the same time for digital cameras, you can also exclude ultraviolet interference on the CCD, help to improve clarity and color also
The excellent function of polarizer is that the light passing through a certain direction can be selectively selected. In color and black and white photography, it is often used to eliminate or weaken the strong reflection of non metallic surface, so as to eliminate or reduce the spot. For example, in the scenery, often used to express strong reflection of the object's texture, highlighting the scene behind the glass, black sky and the performance of blue sky, white clouds, etc..
FLD fluorescence filter: designed for eliminating neon lights, "warm white fluorescent light and green reflection light, clear the deep blue on photos. When using, should avoid photography directly facing the light source. Fluorescent mirror is a kind of special color compensating filter. Under fluorescent lighting shooting using daylight color photos, the screen will appear blue and green, but if you join a fluorescence filter lens (Ying Guangjing). The phenomenon, partial color can be correct, so that the screen color can be restored. The fluorescent mirror provides the correct color, eliminating the bad color of the green fluorescent light bulbs. The fluorescent mirror is actually designed to convert fluorescent light. It provides proper skin color and natural color under fluorescent light. It is the color of magenta, adding warmth to the overall correct color, eliminate bias caused by poor projection of green fluorescent lamp.
