I-Chromakey: Ikhipha Ingemuva & Isikrini Esiluhlaza vs Isikrini Esiluhlaza
Imiphumela ekhethekile iya ngokuya isetshenziswa kumafilimu, uchungechunge kanye nemikhiqizo emifushane. Ngokungeziwe emiphumeleni yedijithali ehlaba umxhwele, yizinhlelo zokusebenza ezicashile ezisetshenziswa kakhulu, njenge-Chromakey.
Lena indlela yokushintsha ingemuva (futhi ngezinye izikhathi nezinye izingxenye) zesithombe ngesinye isithombe.
Lokhu kungasukela kumuntu osestudio ngokuzumayo ome phambi kwephiramidi e-Egypt, ukuya empini enkulu yasemkhathini eplanethini ekude.
Kulokhu okuthunyelwe sizomboza:
Yini i-Chromakey?
Ukuhlanganisa ukhiye we-Chroma, noma ukhiye we-chroma, kuyindlela ekhethekile yemiphumela / ngemva kokukhiqiza yokuhlanganisa (ukwendlalela) izithombe ezimbili noma ukusakazwa kwevidiyo ndawonye ngokusekelwe kumibala yemibala (ububanzi be-chroma).
Indlela isetshenziswe kakhulu emikhakheni eminingi ukususa ingemuva esihlokweni sesithombe noma ividiyo - ikakhulukazi izimboni zokusakaza izindaba, izithombe ezinyakazayo kanye nemidlalo yevidiyo.
Ububanzi bemibala kusendlalelo esingaphezulu benziwa bukhanye, buveze esinye isithombe ngemuva. Indlela ye-chroma keying ivame ukusetshenziswa ekukhiqizweni kwevidiyo nasekukhiqizeni ngemuva.
Le nqubo ibizwa nangokuthi i-color keying, imbondela yokuhlukanisa imibala (CSO; ikakhulukazi i-BBC), noma ngamagama ahlukahlukene okuhlukile okuhlobene nombala okufana nesikrini esiluhlaza, kanye isikrini esiluhlaza okwesibhakabhaka.
Ukufaka i-Chroma keying kungenziwa ngengemuva lanoma yimuphi umbala ofana nohlukile, kodwa ingemuva eliluhlaza neluhlaza okwesibhakabhaka lisetshenziswa kakhulu ngoba lihluke kakhulu ngombala emibaleni eminingi yesikhumba somuntu.
Ayikho ingxenye yesihloko esishuthwayo noma esithwetshulwayo engase iphinde iphinde yombala osetshenziswe ngemuva.
Isinqumo sokuqala okufanele usenze njengomenzi wefilimu Isikrini Esihlaza noma Isikrini Esiluhlaza.
Ukuqalisa ngamabhodi wakho wezindaba anyakazayo
Bhalisela incwadi yethu yezindaba futhi uthole ukulanda kwakho kwamahhala ngamabhodi wezindaba amathathu. Qalisa ngokuletha izindaba zakho ziphile!
Sizosebenzisa ikheli lakho le-imeyili kuphela ukuthola incwadi yethu yezindaba bese siyihlonipha eyakho ubumfihlo
Imaphi amandla ombala ngamunye, futhi iyiphi indlela efaneleka kangcono ukukhiqiza kwakho?
Kokubili okuluhlaza okwesibhakabhaka nokuluhlaza imibala engenzeki esikhumbeni, ngakho ifaneleka kahle kubantu.
Lapho ukhetha izingubo nezinye izinto ezisesithombeni, kufanele uqaphele ukuthi umbala okhiye we-chroma awusetshenziswa.
Isikrini Esiluhlaza okwesibhakabhaka se-Chroma Key
Lona umbala wokhiye we-chroma wendabuko. Umbala awubonakali esikhumbeni futhi unikeza "ukuchitheka kombala" okuncane ongenza ngakho ukhiye ohlanzekile futhi oqinile.
Ezigcawini kusihlwa, noma yimaphi amaphutha avame ukunyamalala ngokumelene nesizinda esiluhlaza okwesibhakabhaka, okungaba futhi inzuzo.
Isikrini Esihlaza Se-Chromakey
Ingemuva eliluhlaza selidume kakhulu ngokuhamba kweminyaka, ngokwengxenye ngenxa yokukhuphuka kwevidiyo. Ukukhanya okumhlophe kufaka u-2/3 wokukhanya okuluhlaza ngakho-ke kungacutshungulwa kahle kakhulu ngama-chip esithombe kumakhamera edijithali.
Ngenxa yokukhanya, kunethuba elikhulu "lokuchitheka kombala", lokhu kuvinjelwa kangcono ngokugcina izifundo zikude nesikrini esiluhlaza ngangokunokwenzeka.
Futhi uma umlingisi wakho egqoke i-jeans eluhlaza okwesibhakabhaka, ukukhetha kwenziwa ngokushesha ...
Kungakhathaliseki ukuthi iyiphi indlela oyisebenzisayo, ukukhanyisa ngisho nangaphandle kwethunzi kubaluleke kakhulu. Umbala kufanele ulingane ngangokunokwenzeka, futhi impahla akufanele icwebezele noma ishwabene kakhulu.
Ibanga elikhulu elinokujula okulinganiselwe kwenkundla lizoncibilikisa imibimbi ebonakalayo kanye ne-fluff.
Sebenzisa isofthiwe enhle ye-chromakey efana ne-Primatte noma i-Keylight, izinkinobho zokungena isofthiwe yokuhlela ividiyo (hlola lezi zinketho) ngokuvamile ukushiya okuthile okufunayo.
Ngisho noma ungawenzi amamuvi amakhulu, ungaqalisa nge-chromakey. Kungaba indlela eyongayo, inqobo nje uma isetshenziswa ngobuhlakani futhi ingaphazamisi umbukeli.

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.
