Emphakathini wanamuhla, ukungcola komoya kuya ngokuya kuba kubi kakhulu, ungqimba lwe-ozone lonakala kancane, futhi izibuko zivezwa emisebeni yelanga ye-ultraviolet. Amashidi e-photochromic ayizinhlayiya ezincane ze-silver halide kanye ne-copper oxide kulensi eziqukethe izinto ezishintsha umbala. Uma zikhanyiswa ukukhanya okunamandla, i-silver halide iyabola ibe yisiliva ne-bromine, kanti izinhlamvu ezincane zesiliva ezibolile zenza ilensi ibonakale insundu emnyama; lapho ukukhanya kuba mnyama, isiliva ne-halide ziphinda zikhiqize i-silver halide ngaphansi kwe-catalysis ye-copper oxide. , ngakho umbala welensi uba lula futhi.
Okwesibili, ukushintsha kombala wefilimu eshintsha umbala
1. Uma libalele: ekuseni, amafu omoya aba mancane, imisebe ye-ultraviolet ayivalwa kakhulu, futhi eminingi ifinyelela phansi, ngakho-ke ukujula kwamalensi ashintsha umbala ekuseni nakho kujule kakhulu. Kusihlwa, imisebe ye-ultraviolet ibuthakathaka, ngoba ilanga likude nomhlabathi kusihlwa, futhi iningi lemisebe ye-ultraviolet ivinjwa ukunqwabelana kwenkungu emini; ngakho ukujula kokushintsha kombala akujulile kakhulu ngalesi sikhathi.
2. Uma kunefu: imisebe ye-ultraviolet ngezinye izikhathi ayibuthakathaka futhi ingafinyelela phansi, ngakho amalensi ashintsha umbala angashintsha umbala. Cishe akukho mbala oshintsha umbala futhi abonakala kahle ngaphakathi, amalensi ashintsha umbala anganikeza izibuko ezifanele kakhulu zokuvikela i-UV kanye nokukhanya kunoma iyiphi indawo, alungise umbala wamalensi ngesikhathi ngokuya ngokukhanya, futhi ahlinzeke ngokuvikelwa kwempilo kwamehlo noma nini, noma kuphi ngenkathi evikela umbono.
3. Ubudlelwano phakathi kwamalensi ashintsha umbala kanye nokushisa: Ngaphansi kwezimo ezifanayo, njengoba izinga lokushisa likhuphuka, umbala wamalensi ashintsha umbala uzokhanya kancane kancane njengoba izinga lokushisa likhuphuka; ngokuphambene nalokho, lapho izinga lokushisa lehla, amalensi ashintsha umbala azoncipha. Kancane kancane ajule. Yingakho kuba nokukhanya ehlobo futhi kube mnyama ebusika.
4. Ijubane lokushintsha kombala, ukujula nakho kuhlobene nobukhulu belensi
