The purpose of the filters in a camera is essentially the same as filters in other tools: capture dirt or large undesirable particles. Camera filters, however, also helps to produce many desirable
effects, creating an overall better end result.
Professional photographers often have more than one filter packed together with their big lenses. Even for beginngers, it is useful to have some different filters on hand.
Some types of filters
There are many types of camera filters, each with its own set of purposes.
1. Ultraviolet (UV) filters absorb UV light. Ultraviolet light is invisible, and the cameras are more sensitive to than the human eye. UV light produces a vapor that can cause interesting details to
the regression as the subject moves away. The clearity and focus of images can also be difficult to achieve if not using a 52mm filter.
2. Infrared filters reduce the visible light. When the penetration of air and mist capture the effects of heat, infrared filters are useful. This type of filter absorbs visible light and transmits only
the infrared light from the lens to the camera.
3. Natural density (ND) filters can be used to obtain the proper exposure in a high intensity lighting. It is also used to produce a specific opening of the lens for sharp images and absorbs light
uniformly across the visible range. In fact, the ND filters modify the light exposure, even without changing the lens aperture.
4. Polarizing filters enhance contrast, reflection and color control. Compared with other filters which are based on different optical principles. Vibrating in one direction, a polarizing filter allows
light to pass through. This type of filter can be aligned in many ways, giving the photo several interesting effects.
polarizing filters are normally used for taking pictures outdoors, because they enhance color saturation and contrast. They also create different colors. For example, a bright yellow light can be
produced using a yellow filter caps.
Reflections from glass surfaces or water can be controlled, or at least minimized, by the polarizers. The recommended angle is 33 degrees from the surface to achieve an impressive result. This filter
can make an object in the water seem to be out of it by simply turning the lens.
5. Optical filters allow different shots with different special effects. These filters can make a subject seem more alive.
If taking pictures is a hobby or profession, the filters are an important part of the array of equipment needed to achieve impressive results. The filters can produce a very noticeable difference in a
photo compared to those without any filtering.
