Ingabe Ngidinga UV-lemifanekiso for ikhamera?

UV Elihehayo - isihlungi UV. Inhloso Its main - ukuvikelwa lens optical ekulimaleni, izintuli nokungcola (konke ngokushesha ebhubhisa lens). Futhi, izakhi optical enjalo kuthiye ukukhula kwe-ultraviolet uma ngokudubula kwezinye izinto ezikude. Ngemva-matrix digital futhi ifilimu, ngokungafani kuya Iso lomuntu liwumsebenzi bazwelane kakhudlwana lolu hlobo ngemisebe. UV Elihehayo iyasiza bethwebula endaweni enezintaba, kuyasiza ukugwema uqwembe blue izithombe.

Yonke esifundeni bohlu ultraviolet ingahlukaniswa amabanga amathathu: ekude - 280 nm futhi mfushane (UV-C); naphakathi - 320-280 NM (UV-B); kanye proximal - 400-320 NM (UV-A). Ukuzwela amadivayisi obuchwepheshe ingaphansi kwe-ifilimu, ngakho-ke kuthatha band proximal, futhi ifilimu uyakwazi ukulungisa zonke ububanzi ultraviolet (kodwa iso babantu abakwazi ukubona akuzona kwesinye salezi amabanga). Nokho, amathuba wefilimu amakhamera kuvimbela ukukwazi lens optical. UV Elihehayo ukusikeka ngokuqhubekayo emisebeni enjalo ngezinye 320 nm (maphakathi zebanga kude).

Lapho ekhetha mkhiqizo kumelwe uqale kusukela ubukhulu lens. Okungukuthi, ukuthola ukuthi yiziphi isihlungi kufanelekile ikhamera yakho, udinga ukwazi ubukhulu lens wentambo (kubonisa ingaphakathi lid). Intengo yomkhiqizo incike ngobukhulu bayo. Njengoba UV Elihehayo ububanzi 52 mm kuyinto $ 10-15 no-77 mm - 30-40 zamadola.

UV izihlungi zihlukaniswe amaqembu amane isigaba:

• Ngiphakathi nendawo - hlangothi, kungekho nto enemibala emihle,
• SkyLight - Pink, siklanyelwe izithombe imibala efudumele;
• UV ngqo - ultraviolet;
• Haze - ngokumelene ufasimbe.

Naphezu umehluko zangaphandle, cabangani ngomgomo leli qembu ingenye - Ukuvikelwa lens emathonyeni zangaphandle, UV nombala zomusi. Ethandwa kakhulu kukhona UV-lemifanekiso Skylight.

Isikhathi esining impela nabathengisi Skylight uvezwa njengoMahluleli engcono ke ezibizayo, kodwa umphumela imibala efudumele esitfombeni senzelwe kuphela ifilimu amakhamera emalini kuyehla zero khona esimhlophe ibhalansi umbala.

Lapho ekhetha mkhiqizo akufanele ukhohlwe ukuthi umsebenzi oyinhloko - ukuvikela lens optical emathonyeni mechanical ukuvikelwa UV, njll - kuyinto yesibili. nayizimfundamakhwela abaningi bangabaze ikhono ukusefa emisebeni ultraviolet, ngoba isithombe nhlobo umphumela (ngokuvumelana umenzi, ukuhlunga ivikela-matrix digital). Ngokusho bezithombe enjalo ukwenziwa izinkampani yokukhanya enezithombe nje cashing ku photographer amateur. Ngakho ngokuvamile batusa ngokukhetha eyodwa noma kwenye yama-isihlungi kusekelwe izakhiwo Ukuvikelwa lokukhanda. Nakuba lens zokuzivikela futhi ezibhekwa eshibhe, kodwa ungakhohlwa ukuthi iyiphi lens - lena ngokuyinhloko isithiyo nokudlulisela ukukhanya, ngakho-ke kungcono kakhulu ukuthenga umkhiqizo nomkhiqizi elihle, eyenziwe high quality materials nge ukudluliswa wokukhanya onamandla.

Sebenzisa UV-izihlungi noma cha, kufanele anqume yena photographer amateur, kodwa ukuthatha izinyathelo zokuzivikela lens, kubalulekile, ngoba intengo uhlelo oluhle optical angaba phezulu ngisho kuka izindleko ikhamera ngokwayo.
