Isizathu esiyinhloko ukuthi kukhona ukuklwebheka emugqeni wefilimu noma ukuvaleka esikrinini esimboziwe, futhi ithusi eliveziwe endaweni engaguquki yongqimba olunamekwe lokulwa nokucwebezela libangela i-PCB ukuthi ihambe kancane.
Thuthukisa izindlela:
1. Ama-negative wefilimu akumele abe ne-trachoma, imihuzuko, njll. Indawo yefilimu yesidakamizwa kufanele ibheke phezulu lapho ibekwe, futhi akufanele ihlikihlwe ngezinye izinto. Ifilimu kufanele isetshenziswe ibheke phezulu lapho ikopishwa. Gcina esikhwameni sefilimu.
2. Lapho iqondana, ifilimu yezidakamizwa ibhekene nebhodi le-PCB. Uma uthatha ifilimu, sebenzisa izandla zakho ukuze uyithathe ngokulinganayo. Ungathinti ezinye izinto ukuze ugweme ukunwaya indawo yefilimu. Uma ifilimu ngayinye iqondaniswe nenani elithile, kufanele uyeke ukuqondanisa. Yihlole noma uyishintshe ngomuntu okhethekile, bese uyifaka esikhwameni sefilimu esifanelekile ngemva kokusetshenziswa.
3. Umsebenzisi akumele agqoke noma yiziphi izinto zokuhlobisa ezifana namasongo, amasongo, njll. Izinzipho kufanele zisikwe futhi zigcinwe zibushelelezi, akukho mfucumfucu okufanele ubekwe phezu kwetafula lekhawunta, futhi indawo yetafula kufanele ihlanzeke futhi ibushelelezi.
4. Isikrini kufanele sihlolwe ngokuqinile ngaphambi kokukhiqizwa, ukuze kuqinisekiswe ukuthi isikrini asivulwa. Uma usebenzisa ifilimu emanzi, ngokuvamile kuyadingeka ukuhlola okungahleliwe ukuze uhlole ukuthi ingabe kukhona udoti ovimbela isikrini. Uma kungekho ukuphrinta isikhathi esithile, isikrini esingenalutho kufanele siphrintwe izikhathi ezimbalwa ngaphambi kokuphrinta, ukuze okuncanyana kuyinki kungancibilikisa ngokuphelele uyinki oqinile ukuze kuqinisekiswe ukuvuza okushelelayo kwesikrini.
