Filters are optical camera accessories that can be inserted into the optical path square-shaped camera that rectangular-mounted accessory holder and generally shaped disc made of glass or plastic with metal or plastic ring frame, which can be opened in front of the camera lens cap. In a sense Wratten filters are identified by numbers.
Filters allow for any change or to be used for the control of the resulting image which can sometimes be used to make subtle changes to the image produced. Lack of using filters is the possibility that poor quality images due to less light or due to a scratched filter, but usually will not be a problem if well planned, but in some situations it is better not to use filters.
Various kinds of camera filters:
• Clear Filter or clean filters, Filter Clear or clear filter is a filter that completely transparent, and does not perform filtering on all incoming light waves. Use this filter is to protect the front of the lens.
• Ultraviolet filters or ultraviolet filter, use this filter to reduce image blur due to wave UV (ultraviolet) the excess transparent like in the mountains and around the beach. This filter is also used for lens protection as well as "clear filter, UV filter also reduces the line of purple fringing in digital cameras, strong UV filters are sometimes used for heating a color photo taken with a shadow in the daytime and a strong UV filter, like UV17-2A can be used to reduce some of the violet light spectrum that has a pale yellow color, this filter is also effective to reduce haze. Excess install UV filters into the lens is made more secure lens from scratches, dust, weather and the lens fell off accidentally, you can clean the filter frequently without having to worry about damage to coating (coating) lens, because if the filter is scratched by cleaning is much cheaper when compared with changing lenses. There is debate among photographers about the use of UV filters: some states that are visually affect the results of the image is worse than egfek lens vignetting in addition lead to heat quickly. while others state that they do not affect and filters which is the protective camera lens.
• Infrared Filter or Filters Infrared, used to filter light having infrared wavelengths that are in opposite sides of spectrum UV light will be forwarded to the sensor or film camera. For the images in the IR you need a filter that filtered only infrared light, but there are some problems with modern cameras. Sensors are built to not record the infrared light, and unless you want to modify your camera permanently (or purchase a specially designed camera like the Canon 20Da). The technique is very unique and strange because it is able to filter the color of chlorophyll (green) leaves resulting in "image to another."
• The filter polarizer, filter polarizer in photography black / white or color photography is used to darken the color of the sky. Because clouds are relatively unchanged, the contrast between clouds and sky increases. The fog in the atmosphere and reflected sunlight can also be reduced by this filter and the overall image color saturation (saturation) colors can be improved. Polarizer filters are not effective on film cameras that are not installed properly. Polarizer filter is often used to handle situations involving imagination, such as involving water or glass, including pictures taken through a glass window (the phenomenon of Brewster's angle). Unlike other filters polarizer filters can not be replaced by the image processing software because most of the optical control of polarization effects when shooting can not be made in the image processing software. There are two types of polarizer filters are linear polarizers and circular polarizers (or CPL filter). Most of the circular polarizer filter polarizer filter is called CirPol or CPL filters and we can change the polarization by rotating the outer layer of the filter. Unlike other filters polarizer filters can be applied to digital photography, even though processed in image processing software because most of the optical control of polarization effects when shooting can not be made in the image processing software.
• Filter Neutral Density Filter Neutral Density or (ND) is used to reduce the amount of light reaching the sensor, which allows photographers to use a larger aperture for a longer time than the aperture in normal circumstances without the filter. One example application of this filter to photograph a waterfall with a slow shutter speed during daylight. Without the lens ND filter at least be able to use a small aperture with long exposure. Medium Filter Graduated Neutral Density (GND) is a neutral filter used in dynamic range due to differences in exposure between highlights (usually the sky) and the shadow face on the bottom side that is too large to obtain the correct exposure for both the one taking pictures, like the sky is likely to overeksposur and the underside of the likely undereposur would be difficult to produce an image with the right exposure. With the usage of this filter will look a little dark sky and the lower face does not happen undereksposur.
• Color correction filters or color correction filters, useful for reducing the lighting effects that are not balanced for the color (white balance), semisalnya, 80A blue filter used with daylight to fix the color orange to reddish in household tungsten lights, while the 85B used for tungsten bluish at noon. Color correction filters are known by numbers sometimes vary from manufacturer to manufacturer, but digital photography, the use of these filters have to be reduced by image processing software after the picture was taken.
• Color subtraction filter or a color reduction filter, used to absorb certain colors of light and let the color of the rest. This filter can be used to dominate the primary colors that form an image. This filter is most often used in the printing industry, especially for color separation and used as a solution digital.Filter photography is commonly used in black and white photography to manipulate contrast. For example a yellow filter will improve contrast between clouds and darkening the sky with the second. Orange and red filters will have a stronger effect in dark green filter so that the sky looks terang.Sebaliknya to reduce the contrast used diffusion filters.
• Color Diffusion Diffusion filters or filter or softens often used for portraits, have the effect of reducing contrast, and filters are designed using some form of grids or nets on filter.Efek on this filter can be obtained with image processing software, which can provide control precise effects of different levels, but the excess of "seeing" with the filter will probably look different. In addition, there will be immediately visible if the contrast is too high on a digital sensor or film, currently in post-image processing is difficult to be compensated due to reduced image contrast. Diffus transparent filter is generally made by modifying the clear filter or UV filter by placing various materials such as petroleum jelly, optical cement, and nail polish. transparent filter is more commonly used to create the effect of "fuzzy" or "foggy" in addition be used to reduce the use of filters kontras.Selain diffusion, diffusion effects or reduction in contrast can be done by placing the lens in front of the box is made of nylon mesh netting.
• Filter or Filters Cross Screen Star, called a star filter because this filter can make a star pattern of lines that spread out from a bright object. Star pattern produced by the rays that come due by the lattice filter or sometimes by the use of prisms in the filter. This filter is widely used in night photography for the light or fluorescent light is more visible.
• Diopters and split diopters Filter filter, Diopters filter that filters often called macro or close-up filter consists of one or two lens elements are used to help focus photography with an object or a close relative such as in fot close-ups and macro photography. They are sometimes sold one by one, and sometimes sold in kits of +1, +2, and +4 diopters, although results are not 1:1 macro, they allow to be able dikombinasikan.Split diopter diopter is a filter that only half of the camera lens is covered by the filter. Split diopter ring round a regular filter, but only a half circle of glass (or plastic). This allows photographers to take pictures of objects that are very close to the background further, effectively extending the DOF or the depth of field.
