Bheka ukuthi kukhanye kangakanani kokubili isihloko sakho nalesi sizinda sangemuva uma usetha ukukhanya - noma yimuphi umehluko ungadala izinkinga zokungafani uma ususa okwasemuva ngedijithali!

Sebenzisa ikhamera yekhwalithi ephezulu

Ukusebenzisa a ikhamera yekhwalithi ephezulu ngeke kusize nje ukudala isithombe sekhwalithi engcono ngokujula okungcono kwensimu, kodwa futhi kuzonciphisa inani lomsebenzi wangemuva kokukhiqiza okudingeka uwenze. Ukukhiqizwa kwangemuva kuyadingeka ukuze ucwenge noma yikuphi ukuqoshwa kwesikrini okuluhlaza, futhi ukuba nekhamera yekhwalithi ephezulu kuzosiza ukunciphisa isikhathi esisithathayo ukushuna ividiyo yakho mathupha.

Zama ukuthola amakhamera anama-megapixel aphezulu futhi eze nesofthiwe engasiza ukuthuthukisa izici ezifana nokugqama noma ukugcwaliswa kwesikhala. Kubalulekile futhi ukubheka amakhamera anakho Amandla obubanzi obuhlukahlukene, njengoba lokhu kuzosiza ukwenza izithombe zakho zibonakale zingokwemvelo futhi ziphansi kancane.

Okokugcina zama ukuba nezinketho eziningi zokukhanyisa ezitholakala kusethi njengoba lokhu kungashintsha umuzwa wesithombe kakhulu—ungase ufune amazinga ahlukene okukhanya kuye ngokuthi ufuna uhlobo luni lwesithombe.

Uma usebenzisa izikrini eziluhlaza ze-VFX, umthetho omuhle wesithupha ukuthi kufanele uhlale njalo phutha ohlangothini lokuqapha futhi uthathe izinyathelo zokuphepha ezengeziwe lapho usetha amashothi akho ukuze uthole ukusebenza okuhle kakhulu kuwo.

Sebenzisa i-tripod ukuze uzinze

Izithombe eziningi zesikrini eziluhlaza zidinga izinga elihle lokuzinza. Okufanelekile kufanele usebenzise i-tripod futhi uqiniseke ukuthi isibhamu sakho sivaliwe ngaphandle kwe-cha ukunyakaza. Kubalulekile ukugcina amashothi aphathwayo engashintshi uma uwasebenzisa njengoba kuzoba nzima kakhulu ukuwahlanza uma iyanyakaza noma ihambahamba. Ungasebenzisa futhi ingalo kadoli noma ye-jib ukunyakaza okuguquguqukayo, kodwa qiniseka ukuthi kunjalo esebenza kahle nokuthi ikhamera kuvaliwe ngaphambi kokuthi uqale ukuqopha.

Sebenzisa amamakrofoni ahlukene: Ukusebenzisa amamakrofoni amabili - owodwa ngesiphiwo kanti omunye owomsindo wegumbi - kusiza ukugcina imisindo ezungezile efana nesiphephetha-moya kanye nethrafikhi kude nethrekhi yomsindo eyinhloko esetshenziselwa izinjongo zangemuva. Womabili amamakrofoni adala womabili i- ithrekhi kuma kanye a ithrekhi yenkhulumomphendvulwano okuzohlinzeka abahleli bomsindo ngokuguquguquka okuthile ekukhiqizweni ukuze bakhe ithrekhi yomsindo engenazihibe.

Shutha amabanga ahlukahlukene: Kubalulekile ukuthatha amashothi amaningi kuwo amabanga ahlukahlukene lapho udubula izikrini eziluhlaza njengoba lokhu kuzonikeza umhleli wakho izinketho eziningi lapho uhlanganisa isithombe sokugcina. Ukuba namashothi aseduze namashothi abanzi kubalulekile ekunikezeni izinguquko ezingokoqobo phakathi kwesizinda ngemuva kokukhiqizwa, ngakho qiniseka ukuthi unokuningi ukuthwebula izithombe ezindaweni ezahlukene.

Gcina ukukhanya kufana: Ukukhanyisa kufanele kube engaguquki kukho konke ukuthwebula kwakho ukuze abaculi be-digital matte (ama-DMA) basebenze kahle lapho behlanganisa ingemuva ledijithali kuvidiyo yakho ekukhiqizweni kwangemuva. Kungcono ukuzijwayeza uku vala yonke imithombo yokukhanyisa ngenkathi udubula futhi uqinisekise ukuthi zikhona kusatshalaliswa ngokulinganayo kuyo yonke indawo yesithombe kunokuba nje ithalente lakho libekwe kuhlaka. Ngale ndlela, ama-DMA angathatha izilinganiso kunoma iyiphi ingxenye yohlaka uma edinga ukukhohlisa amaleveli okukhanya phakathi nenqubo yawo yokuhlanganisa.

Isiphetho

Ukusetshenziswa kwefayela le- isikrini esiluhlaza inikeza abenzi befilimu nabathwebuli bevidiyo ngezwe lezinketho lapho benza okuqukethwe. Kungakhathaliseki ukuthi usebenzisa ividiyo yesenzo esibukhoma noma izici ezigqwayizayo, umgomo wokugcina uwukuthwebula izethameli nokudala ukulandisa. Ngokulandela izinqubo ezinhle zokudubula nokusebenzisa amasu okuhlanganisa akamuva, ukukhiqizwa kwesikrini esiluhlaza kunganikeza ababukeli umuzwa ohehayo ogcwele impilo nezimangaliso.

Ukusebenzisa isikrini esiluhlaza kudinga ukuhlelwa kwangaphambili kokukhiqiza ukuze usebenzise ngempumelelo izinzuzo zaso. Ngamathuluzi alungile, isiqondiso sokudala, namasu okwenziwa ngemva kokukhiqiza, abenzi bamafilimu bangahlanganisa amakhono abo ukuze bakhe amafilimu namavidiyo agqama ngempela emqhudelwaneni. Ngokugxila ezimisweni zokukhanyisa ezisebenzayo, ukuqonda amasu okudubula, noma ukuthembela kumathuluzi edijithali kanye umdwebo we-matte amaqhinga, kancane kancane izithombe zakheka zizungeze imibono zibe izigcawu eziheha izethameli emhlabeni jikelele.

Njengoba sekushiwo ngenhla kuyamangaza ukuthi yini ongayenza uma usebenzisa amandla izikrini eziluhlaza!

Sawubona, nginguKim, umama kanye nomshisekeli we-stop-motion onesizinda ekudalweni kwemidiya nokuthuthukiswa kwewebhu. Nginothando olukhulu lokudweba nokugqwayiza, futhi manje sengingena ngekhanda emhlabeni onyakazayo. Ngebhulogi yami, ngabelana ngezifundo zami nani bafana.
