Hamwe n'amasaha menshi yo kumanywa hamwe nizuba ryinshi ryizuba, kugenda mumihanda, ntabwo bigoye kubona ko abantu benshi bambaye lensifoto kuruta mbere. Indorerwamo z'izuba zagiye ziyongera cyane mu bucuruzi bw'imyenda y'amaso mu myaka yashize, kandi ibyuma bifotora bikomeza kuba ibicuruzwa byo mu mpeshyi. Isoko hamwe n’abaguzi bemera amafoto yerekana amafoto akomoka muburyo bwabo, kurinda urumuri, hamwe nibikenewe bijyanye no gutwara.
Muri iki gihe, abantu benshi bazi ibyangiritse imirasire ya ultraviolet ishobora gutera uruhu. Imirasire y'izuba, parasole, imipira ya baseball, ndetse n'ibipfukisho by'amaboko ya silike byahindutse ibintu by'ingenzi byo gusohoka mu mpeshyi. Ibyangiritse imirasire ya UV ikora kumaso ntibishobora guhita bigaragara nkuruhu rwanduye, ariko mugihe kirekire, guhura cyane birashobora gutera ingaruka zikomeye. Indwara zamaso nka cataracte hamwe nimyaka zijyanye no guta imyaka byagaragaye ko bifite aho bihurira cyangwa bitaziguye na UV. Kugeza ubu, abaguzi b’abashinwa ntibafite igitekerezo kimwe cy '"igihe cyo kwambara amadarubindi" bitewe n’izuba. Akenshi, ibidukikije byo kumurika hanze bisaba kurinda urumuri, ariko abaguzi benshi bumva ko "bidakenewe" bagahitamo kutambara. Kuruhande rwinyuma, ibyuma bifotora, bitanga icyerekezo cyo gukosora no kurinda urumuri bitabaye ngombwa ko bivanwaho nkamadarubindi asanzwe yizuba ahantu hatandukanye, bigenda byemerwa mubantu benshi.
Ihame ryo guhindura amabara mumafoto yerekana amafoto ashingiye kuri "fotochromism." Mugihe cyo hanze, utwo turemangingo twijimye kugirango tumeze nk'amadarubindi y'izuba hanyuma usubire mu mucyo no mu mucyo. Ibi biranga bifitanye isano nibintu bizwi nka silver halide. Mugihe cyo gukora, abakora lens binjiza shingiro cyangwa firime ya lens hamwe na microcrystal ya silver halide. Iyo ihuye nurumuri rukomeye, igice cya feza cyangirika mo ion na halide ion, gikurura urumuri rwinshi rwa ultraviolet numucyo ugaragara. Iyo urumuri rwibidukikije rugabanutse, ioni ya feza na halide ion zongera guhinduka igice cya feza munsi yo kugabanya ibikorwa bya oxyde y'umuringa, bigatuma ibara rya lens ryoroha kugeza ryongeye kugaragara neza.
Guhindura ibara mumashusho yerekana amafoto nigisubizo cyuruhererekane rwimiti ihindagurika, hamwe nurumuri (harimo urumuri rugaragara na ultraviolet) rufite uruhare runini muribi bitekerezo. Mubisanzwe, imikorere yuburyo bwo guhindura ibara iterwa nibihe hamwe nikirere, ntabwo rero bigumana ingaruka zihamye kandi zihamye.
Muri rusange, mubihe by'izuba, ubukana bw'imirasire ya ultraviolet burakomera, biganisha ku gufotora cyane, kandi lens zijimye cyane. Ibinyuranye, muminsi yibicu, iyo imirasire ya UV nuburemere bwurumuri bigenda bigabanuka, lens igaragara nkurumuri. Byongeye kandi, uko ubushyuhe buzamuka, ibara ryamafoto ya fotokromike rigenda ryoroha. Ibinyuranye, iyo ubushyuhe bugabanutse, lens zijimye buhoro buhoro. Ni ukubera ko ku bushyuhe bwo hejuru, ion ya feza na halide ion, zabanje kubora, zigabanuka zisubira mu gice cya feza munsi y’ingufu nyinshi, zorohereza ibara ry’inzira.
Kubijyanye na foto ya fotokromike, hariho ibibazo bimwe bisanzwe hamwe nubumenyi:
Lens ya fotokromike ifite urumuri rwo hasi rwohereza / gusobanuka ugereranije ninzira zisanzwe?
Ibyuma bifotora byujuje ubuziranenge ntibifite ibara rwose iyo bidakozwe kandi ntibifite urumuri ruto ugereranije nubusanzwe.
Ni ukubera iki lens fotokromike idahindura ibara?
Kubura ibara ryibara ryamafoto afitanye isano nibintu bibiri: imiterere yumucyo hamwe na fotokromike (silver halide). Niba badahinduye ibara no mumucyo mwinshi hamwe nimirasire ya UV, birashoboka ko fotokromike yangiritse.
Ese ingaruka zo guhindura ibara za fotokromic lens zizagenda ziyongera mugihe runaka?
Kimwe nubundi buryo busanzwe, lensifoto nayo ifite igihe cyo kubaho. Hamwe no kwitabwaho neza, muri rusange bimara imyaka 2-3.
Ni ukubera iki lens fotochromic ihinduka umwijima burundu mugihe runaka?
Niba amafoto ya fotokromike yijimye mugihe kandi ntashobora gusubira muburyo buboneye, ni ukubera ko imashini yabo ifotora idashobora gusubira muburyo bwayo nyuma yo guhindura ibara, bikavamo ibara risigaye. Iyi phenomenon ikunze kugaragara cyane murwego rwohejuru, mugihe ubuziranenge bwiza bwamafoto atazagira iki kibazo.
Ni ukubera iki ibara ryijimye risanzwe ku isoko?
Icyatsi kibisi gishobora gukurura infragre na 98% yimirasire ya UV. Inyungu nini yibara ryinshi ni uko idahindura amabara yumwimerere yibintu, bikagabanya neza ubukana bwurumuri. Zikurura urumuri kuringaniza ibice byose, ibintu rero bigaragara ko ari umwijima ariko nta kugoreka amabara kugaragara, bitanga ukuri kandi karemano. Byongeye kandi, imvi ni ibara ridafite aho ribogamiye, rikwiranye na buri wese, bigatuma rikundwa cyane ku isoko.
