DJI MAVIC Pro UAV filter accessories UV / Starlight / dimming additional effect of the mirror set UV lens for sea, mountain, snow and open areas such as shooting under the environment, can weaken the blue caused by ultraviolet light. At the same time for digital cameras, you can also rule out the interference of ultraviolet on the CCD, help to improve the clarity and color reproduction effect. CPL (circular polarizer) is generally will have the filter, generally used for landscape photography, eliminate unnecessary polarized light, so that the whole picture is more clear, more transparent feeling, but how to use it Can see the effect? This article will introduce the use of CPL skills, principles and methods of application Color filters are also called “filters”. An optical device that selectively absorbs (or passes) light in different wavelength bands. By the mirror ring and filter components, often installed in front of the camera or camera lens. Black and white photography with the color filter is mainly used to correct the black and white color and adjust the contrast, to eliminate interference with light; color photography with the color filter is mainly used to correct the color temperature of the light source, the color compensation. Starlight mirror is a kind of camera filter to the light-emitting point as the center, sub-4 lines, 6 lines, 8 lines, which is colorless optical glass surface regularly etched a series of parallel lines, resulting in diffraction of light And the effect of the formation of radiance, which is a stage or night shot when the effect of the mirror will be able to play an extraordinary role for the screen. The photo shows the effect of shooting with a star mirror. Gradient mirror, also known as the [GND filter] is a photographic art creation is extremely important one of the filters, it can be divided into gradient color mirror and gradient diffuse mirror, from the gradient can be divided into soft and hard gradient, soft “That is a large transition range, on the contrary, that the transition range is small, are required to select according to the creative features. Adjustable ND filter has a variety of density to choose from, such as ND2, ND4, ND8, multi-chip neutral gray mirror can also be used in combination. It is not difficult to see, ND behind that figure, which represents the ND mirror blocking light ability. The adjustable dimmer, as the name suggests is to adjust the ND value by rotating the lens, which is more convenient for us to reduce the light shooting. But also the color of light-color technology products model.
