Amafilimu e-stretch manje asetshenziswa kabanzi ezimpilweni zethu nasemsebenzini. Amafilimu esiwabonayo ngokuvamile awanambala futhi asobala, kodwa lapho siwasebenzisa, siye saqaphela ukuthi amafilimu amaningi alula azoba nomunye Umbala, ifilimu elula inemibala eminingi, ukusetshenziswa okuhlukene kusetshenziselwa ukusebenzisa imibala ehlukene, ngakho-ke ukuhambisana kombala inqubo iyinqubo ebalulekile ekukhiqizeni ifilimu elula.
1. Ukufanisa imibala ebonakalayo: Kubasebenzi abafanisa imibala abanokuhlangenwe nakho kumafilimu anwebekayo, ngaphambi kokumataniswa kombala, kufanele babe nomqondo ocacile wombala abawudingayo, futhi basebenzise umthetho ovamile wokufaka imibala kumbala oxubile. Yiba nokuqonda okucacile kokusebenza kombala osetshenzisiwe, futhi uqongelele amapulasitiki amaningi amele. Indlela yokufanisa umbala obonakalayo iyindlela enhle yokuhlola, kodwa ayiyona isayensi kakhulu, ngakho isebenza kuphela futhi ilula. Ukufanisa umbala, kodwa futhi kudinga opharetha ukuba babe nolwazi olucebile lokufanisa imibala, ngaphandle kwalokho kuzoba nzima ukusebenza.
2. Ukufanisa umbala wensimbi: Indlela yokusebenzisa insimbi ukufanisa umbala wefilimu enwetshiwe empeleni iyindlela etholakala enqubweni yokufanisa imibala ebonakalayo. Le ndlela isebenzisa i-photometer nezinye izinsimbi zokulinganisa ukuze kuthathelwe indawo iso lomuntu nobuchopho. Umsebenzi wesilinganiso sombala, inqubo yesilingo yesilinganiso sombala nayo yenziwa ngokulingisa ikhompyutha, ngaphandle kokusetshenziswa kwangempela okuxubile kombala wepulasitiki, futhi opharetha udinga kuphela ukukala ukubonakaliswa, okuyinani layo elijwayelekile, bese ukhetha ukuyisebenzisa. . Izingulube ezihambisana nombala zanele. Ngokulungisa ukugxiliswa kombala ofanisa umbala, inani lokuguqulwa lesistimu yokulinganisa lihambisana nezinga. Uma u-opharetha ekhetha okunengqondo, isistimu izokhipha ifomula ngendlela ye-mass score, bese Ngokwale fomula, iguqulwa ibe isilinganiso sobuningi.
