Kodi ndifunika UV-fyuluta kamera?

UV-fyuluta - ndi UV fyuluta. cholinga chake chachikulu - chitetezo cha magalasi kuwala zisaonongeke, fumbi ndi uve (zonse mofulumira wawononga mandala). Komanso, ngati zinthu kuwala achigonjetse kuwala pamene kuwombera zinthu kutali. Pambuyo digito masanjidwewo ndi film, mosiyana ndi diso la munthu womvera mtundu wa poizoni. UV-fyuluta ndi zothandiza kwambiri kwa zithunzi m'dera lamapiri, zimathandiza kupewa chikwangwani cha buluu zithunzi.

Dera lonse la ultraviolet sipekitiramu akhoza kugawidwa ranges atatu: kutali - 280 nm ndi lalifupi (UV-C); sing'anga - 320-280 nm (UV-B); ndi proximal - 400-320 nm (UV-A). Tilinazo zipangizo digito n'chozama kupitirira filimu, choncho imatenga proximal gulu, ndi filimu amatha kukonza onse ultraviolet osiyanasiyana (koma ndi diso la munthu sangathe kuwona simuli mmodzi wa ranges izi). Komabe, mwayi makamera filimu kukuchepetsa luso magalasi kuwala. UV-fyuluta mabala cheza oterowo 320 nm (pakati ndi kutali osiyanasiyana).

Posankha mankhwala amenewa muyenera kuyambira m'mimba mwake disolo. Kutanthauza kuti tipeze zomwe fyuluta ndi oyenera kamera anu, muyenera kudziwa disolo awiri a ulusi (umasonyeza mkati mwa chivindikiro cha). Mtengo wa mankhwala zimadalira kukula kwake. Popeza UV-fyuluta awiri a 52 mamilimita ndi $ 10-15, ndi 77 mm - 30-40 dollars.

Zosefera UV agawidwa m'magulu anayi gulu:

• Mbali - ndale, colorless;
• SkyLight - Pinki, lakonzedwa kupereka zithunzi za mitundu ofunda;
• mwachindunji dzuwa - ultraviolet;
• Chifunga - ndi Chifunga lapansi.

Ngakhale kusiyana kunja, cholinga cha gulu limeneli ndi limodzi - mandala chitetezo makhalidwe kunja, UV ndi mtundu wa utsi. Wotchuka kwambiri ndi UV-fyuluta ndi Skylight.

Nthawi zambiri ogulitsa Skylight kuperekedwa monga bwino choncho mtengo, koma zotsatira za mitundu otentha mu chithunzi cholinga okha makamera filimu pa chithunzi icho yafupika ziro ndi kukhalapo kwa woyera bwino mtundu.

Posankha mankhwala amenewa Tisaiwale kuti Ntchito yaikulu - ndi kuteteza mandala kuwala asatengere makina ndi dzuwa chitetezo, etc. - ndi sekondale. Amateurs ambiri amakayikira zosefera luso cheza ultraviolet, chifukwa chithunzi pafupifupi ziribe mphamvu (monga Mlengi, fyuluta amateteza digito masanjidwewo). Malinga ndi ojambula amenewa kwa kupanga makampani Zithunzi Optics Kungoti cashing pa wojambula zithunzi ankachita masewera. Nthawi zambiri amavomereza kusankha wina UV-fyuluta zachokera katundu chitetezo makina. Ngakhale magalasi oteteza ndi amaonedwa yotsika mtengo, koma musaiwale kuti mandala iliyonse - ichi makamaka chotchinga kufala kwa kuwala, choncho ndi bwino kugula malonda ku kampani yopanga otchuka, yopangidwa ndi zisulo apamwamba ndi HIV amphamvu kuwala.

Ntchito UV-zosefera kapena ayi, ayenera kusankha yekha ndi wojambula zithunzi ankachita masewera, koma amayesetsa kuteteza mandala, m'pofunika, chifukwa mtengo wa bwino dongosolo kuwala mwina kuposa mtengo wa kamera yokha.
