Lens Filters

Lens Filters used by many photographers, sinceDigital processing is not always capable of leading to the required quality of images. The most common filters are polarization, protective, neutral, gradient, and color.
Protective filters suitable for all types of shooting: from landscape to portrait. They are used primarily to protect the front lens of the lens. Such filters are necessarily installed on expensive lenses.
Polarization filters for lenses play an important role in the landscape andlandscape photography. They are necessary in order to reduce the amount of reflected light that falls on the sensor of the camera. Thanks to polarization filters, the clear sky in the photos looks less bright and acquires a kind of blue. It should be noted that such filters are able to completely suppress glare on all surfaces, except for metallic ones.
Concerning neutral filters, they will be useful for smoothing the movementwater in fast rivers or waterfalls. Also with their help you can achieve a shallower depth of field in bright light conditions. Thanks to neutral filters, blurring of moving objects, for example, cars or people, is easy.
Gradient filters For lenses designed to reduceillumination in accordance with a certain geometric pattern. Such filters are ideal for landscape photography with a simple light geometry. As a rule, the dark side of the filter is used to darken the sky, which in most cases is much brighter than the surface of the earth and is capable of creating so-called "overexposures". It should be noted that to use such filters it is recommended to use a tripod, since it will be necessary to use a rather long shutter speed.
In its turn, color filters apply to correct the color ratio. For example, with their help you can add warmth on a cloudy day, so that the photo looks like it was done at sunset. Recently, such filters for lenses are used very rarely, since color correction can be performed using a computer, in addition, modern digital SLR cameras allow you to manually adjust the white balance, because this parameter regulates the heat of the frame.
It should be noted that the filters are invoices and screwed. The former are considered more universal and canUsed with lenses of different diameters, however, during shooting, you will have to keep this filter by hand in front of the lens. On the other hand, there are special fixers on sale that can simplify the creation of images.
The only drawback of screw-on filters is fixed thread diameter, which can vary from 46 to 82 millimeters. To buy filters in this case, you need to take into account the diameter of the lens itself.
Finally, it must be said that Use filters only if necessary, as they can easily spoil the photo,reducing its contrast. It is also possible the appearance of a so-called vignette, which is a darkening at the edges of the frame. However, some photographers consider this effect to be very interesting and often use it.
