Na ke lokela ho ba le UV-filtara bakeng khamera?

UV-filtara - le UV filthara. morero oa oona ka sehloohong - tshireletso ya le lilense Optical tloha senya, lerōle le mobu (kaofela ka potlako timetsa lense). Hape, joalo likarolo Optical khina mahlaseli khanya ha thunya beha dintho tse hōle. Mora ditsitithale popeho le filimi, ho fapana ho ea Leihlo la motho e ela hloko haholoanyane ho mofuta ona wa mahlaseli. UV-filtara na le thuso haholo bakeng sa ho photographing ka sebakeng se lithaba, ho thusa ho qoba mongolo putsoa ka foto.

Sebakeng sohle sa mahlaseli a manyenyane a ka arotsoe ka mekoloko tse tharo: hōle - 280 NM le khutšoanyane (UV-C); mahareng - 320-280 NM (UV-B); le proximal - 400-320 NM (UV-A). Nahanela disebediswa tsa ho ditsitithale e tlaase ho feta filimi, kahoo ho nka e proximal sehlopha, 'me filimi o khona ho lokisa tsohle ya mahlaseli mefuta e fapaneng (empa mahlo a motho o ke ke a bona ha ho e mong oa mekoloko tsena). Leha ho le joalo, le menyetla e la lik'hamera filimi thibela bokhoni ba lilense Optical. UV-filtara fokotsa ho mahlaseli a kotsi joalo ka 320 NM (bohareng le hole le fihleleha).

Ha a khetha sehlahisoa jwalo o lokela ho qala ho ho tswa ho bophara ba lense. Ke hore, ho fumana hore leo filtara loketse bakeng la kh'amera hao, u lokela ho tseba lense bophara tsa tshekatsheko ya (it e bontsha ka hare ea sekwahelo e). Theko ea sehlahiswa e itšetlehile ka boholo ba eona. Kaha UV-filtara bophara ba 52 limilimithara ke $ 10-15, 'me 77 limilimithara - 30-40 liranta.

filter UV ba arotsoe ka lihlopha tse 'nè tse sehlopha:

• Nke lehlakore - nke lehlakore, colorless;
• SkyLight - Pink, e reretsoe ho fana ka litšoantšo tse mebala-bala mofuthu;
• kotloloho UV - mahlaseli;
• Haze - khahlanong haze ena.

Ho sa tsotellehe ho se tšoane ka ntle, pakane ea sehlopha sena ke e 'ngoe - lense sireletsa litšusumetso ka ntle, UV le mebala ea mosi. Ka ho fetisisa ratoa ke UV-filthara le Skylight.

hangata haholo barekisi Skylight hlahisoa e le molemo ka ho fetisisa 'me ka hona e theko e boima, empa phello ea mebala e mofuthu ka photo photo photo photo e reretsoe feela bakeng sa lik'hamera filimi ka palo eo e fokotsehile ho lefela ka ho ba teng ha ho e tšoeu ho leka-lekana ' mala.

Ha a khetha sehlahisoa joalo ba lokela ho ke ua lebala hore mosebetsi ya sehlooho - ke ho sireletsa lense Optical litšusumetsong mechine le UV tšireletso, joalo-joalo - e mahareng. phihlelo litabeng tsa ntoa tse ngata belaella filtara bokhoni ba mahlaseli mahlaseli, hobane photo photo photo photo ke hoo e batlang e ha ho na le phello (ho latela moetsi, filthara sireletsa ditsitithale popeho). Ho latela lifoto joalo bakeng sa ho hlahisa lik'hamphani lifoto optics ba mpa feela cashing ka ka photographer tsenwe. Hangata khothalletsa ho khetha e itseng UV-filtara e thehiloeng thepa ea tšireletso phetha molao feela. Leha lilense sireletsang 'me ba nkoa e le maleewana, empa u se ke ua lebala hore lense efe kapa efe - sena ke haholo-holo e le mokoallo le phetiso ea leseli, kahoo ho molemo ho reka sehlahisoa le tsoang ho moetsi le botumo bo botle, entsoe ka thepa ea boleng bo phahameng le e phetiso matla leseli.

Sebelisa UV-filter, kapa che, ba lokela ho etsa qeto ka boeena o oa, photographer tsenwe, empa ho nka mehato ea ho sireletsa lense, ho ke ke ho hlokahala, hobane theko ea e ntle tsamaiso e khopo Optical ka 'na ba esita le phahame ho feta litšenyehelo tsa khamera ka boeona.
