● Singayisebenzisa nini? Itholakala usuku lonke. Ngenxa yokuphuma okuqhubekayo kokukhanya okuluhlaza okuvela elangeni, ukukhanya kwento, imithombo yokukhanya yokwenziwa, nezinto zikagesi, kungalimaza amehlo abantu. Amalensi ethu asebenzisa ubuchwepheshe obuthuthukisiwe bokuchazwa okuphezulu kokuvikela ukukhanya okuluhlaza okwesibhakabhaka, okusekelwe kumbono webhalansi yombala ukuze kuncishiswe ukuphuma kwe-chromatic, angamunca futhi avimbe ukukhanya okuluhlaza okulimazayo (avimbe ngempumelelo i-UV-A, i-UV-B kanye nokukhanya okuluhlaza okunamandla aphezulu) futhi abuyisele umbala wangempela wento ngokwayo .
● Ilekelelwa inqubo yesendlalelo sefilimu ekhethekile, ingakwazi ukufeza ukumelana nokuguga, ukunqanda ukukhanya, ukukhanya okuphansi, okulwa ne-UV, ukukhanya okuluhlaza okwesibhakabhaka, ukungangeni kwamanzi nokungangcolisi, kanye nemiphumela yokubuka ye-HD.
