Feem ntau, cov xim hloov cov iav tsom iav tuaj yeem tsis tsuas yog ua kom yooj yim thiab kev zoo nkauj tab sis kuj tuaj yeem tiv thaiv ultraviolet thiab glare, tuaj yeem tiv thaiv ob lub qhov muag, vim li cas cov xim hloov xim yog thaum lub lens tsim, nws yog tov nrog cov khoom siv lub teeb. , xws li nyiaj chloride, nyiaj halide (collectively hu ua silver halide), thiab ib tug me me ntawm tooj liab oxide catalyst. Thaum twg cov nyiaj halide illuminated los ntawm lub teeb muaj zog, lub teeb yuav decompose thiab dhau los ua ntau cov nyiaj dub sib npaug sib npaug hauv lub lens. Yog li ntawd, lub lens yuav tshwm sim dim thiab thaiv txoj kev ntawm lub teeb. Lub sijhawm no, lub lens yuav dhau los ua xim, uas tuaj yeem tiv thaiv lub teeb kom ua tiav lub hom phiaj ntawm kev tiv thaiv lub qhov muag.

Xim-hloov lo ntsiab muag darken thaum lub hnub ci. Thaum lub teeb ci ploj mus, nws rov qab ci dua. Qhov no yog ua tau vim hais tias cov nyiaj halide crystals nyob rau hauv ua hauj lwm.
Nyob rau hauv ib txwm muaj xwm txheej, nws ua rau cov lo ntsiab muag zoo kawg nkaus pob tshab. Thaum raug tshav ntuj, cov nyiaj hauv cov siv lead ua yog sib cais, thiab cov nyiaj dawb ua cov ntaub ntawv me me hauv lub lens. Cov nyiaj me me no tsis sib xws, sib cuam tshuam clumps uas tsis tuaj yeem xa lub teeb tab sis nqus nws, ua rau lub lens darkening. Thaum lub teeb qis, cov siv lead ua hloov pauv thiab lub lens rov qab los rau nws lub teeb ci.
