Chromakey: Kuchotsa Background & Green Screen vs Blue Screen
Zotsatira zapadera zikugwiritsidwa ntchito kwambiri m'mafilimu, mndandanda ndi kupanga zazifupi. Kuphatikiza pa zochititsa chidwi za digito, ndizomwe zimagwiritsidwa ntchito mosabisala zomwe zimagwiritsidwa ntchito kwambiri, monga Chromakey.
Iyi ndi njira yosinthira maziko (ndipo nthawi zina mbali zina) za chithunzicho ndi chithunzi china.
Izi zitha kukhala kuchokera kwa munthu mu studio mwadzidzidzi atayima kutsogolo kwa piramidi ku Egypt, kupita kunkhondo yayikulu yam'mlengalenga padziko lakutali.
Mu positi iyi tikambirana:
Kodi Chromakey ndi chiyani?
Chroma key compositing, kapena chroma keying, ndi njira yapadera / yopangira pambuyo popanga (kusanjikiza) zithunzi ziwiri kapena makanema amakanema palimodzi kutengera mitundu yamitundu (mitundu ya chroma).
Njirayi yakhala ikugwiritsidwa ntchito kwambiri m'magawo ambiri kuchotsa mbiri yakale pamutu wa chithunzi kapena kanema - makamaka makampani opanga nkhani, zoyenda ndi masewera a kanema.
Mtundu wamtundu wamtundu wapamwamba umawonekera, kuwululira chithunzi china kumbuyo. Njira ya chroma keying imagwiritsidwa ntchito kwambiri popanga makanema komanso kupanga pambuyo.
Njira imeneyi imatchedwanso color keying, color-separation overlay (CSO; makamaka ndi BBC), kapena ndi mawu osiyanasiyana okhudzana ndi mitundu monga green screen, ndi skrini ya buluu.
Chroma keying ikhoza kuchitidwa ndi maziko amtundu uliwonse womwe uli wofanana komanso wosiyana, koma zobiriwira ndi zabuluu zimagwiritsidwa ntchito kwambiri chifukwa zimasiyana kwambiri ndi mitundu yambiri ya khungu laumunthu.
Palibe gawo lankhani yomwe ikujambulidwa kapena kujambulidwa yomwe ingafanane ndi mtundu womwe wagwiritsidwa ntchito kumbuyo.
Chosankha choyamba chomwe muyenera kupanga ngati wopanga mafilimu ndi Sewu Yamtundu kapena Blue Screen.
Kuyamba ndi zolemba zanu zoyimitsa nkhani
Lembetsani ku kalata yathu yamakalata ndikutsitsa kwaulere ndi zolemba zitatu. Yambani ndikupangitsa nkhani zanu kukhala zamoyo!
Tidzangogwiritsa ntchito imelo yanu kutsamba lathu ndikulemekeza lanu zachinsinsi
Kodi mphamvu zamtundu uliwonse ndi ziti, ndipo ndi njira iti yomwe ikugwirizana bwino ndi kupanga kwanu?
Mitundu yonse ya buluu ndi yobiriwira ndi yomwe simapezeka pakhungu, choncho ndi yoyenera kwa anthu.
Posankha zovala ndi zinthu zina zomwe zili pachithunzichi, muyenera kumvetsera kuti mtundu wachinsinsi wa chroma sugwiritsidwa ntchito.
Chroma Key Blue Screen
Uwu ndiye mtundu wachikale wa chroma key. Mtunduwu suwoneka pakhungu ndipo umapereka "kutayika kwamtundu" pang'ono komwe mutha kupanga kiyi yoyera komanso yolimba.
M'mawonekedwe madzulo, zolakwa zilizonse nthawi zambiri zimatha motsutsana ndi maziko a bluish, zomwe zingakhalenso zopindulitsa.
Chromakey Green Screen
Zobiriwira zobiriwira zakhala zikudziwika kwambiri pazaka zambiri, makamaka chifukwa cha kukwera kwa kanema. Kuwala koyera kumakhala ndi 2/3 ya kuwala kobiriwira motero kumatha kukonzedwa bwino kwambiri ndi tchipisi tazithunzi mumakamera a digito.
Chifukwa cha kuwala, pali mwayi waukulu wa "kutayika kwamtundu", izi zimatetezedwa bwino posunga maphunzirowo kutali ndi chophimba chobiriwira momwe zingathere.
Ndipo ngati wojambula wanu atavala ma jeans abuluu, kusankha kumapangidwa mwachangu ...
Mosasamala kanthu za njira yomwe mumagwiritsa ntchito, kuyatsa ngakhale opanda mithunzi ndikofunikira kwambiri. Mtundu uyenera kukhala wofanana momwe ungathere, ndipo zinthuzo zisakhale zonyezimira kapena makwinya kwambiri.
Mtunda waukulu wokhala ndi kuzama kocheperako umasungunula makwinya owoneka ndi fluff.
Gwiritsani ntchito mapulogalamu abwino a chromakey monga Primatte kapena Keylight, ma keyers in pulogalamu yosinthira makanema (onani zosankha izi) nthawi zambiri amasiya chinthu chomwe angafune.
Ngakhale simupanga makanema akuluakulu, mutha kuyamba ndi chromakey. Ikhoza kukhala njira yotsika mtengo, pokhapokha itagwiritsidwa ntchito mwanzeru komanso yosasokoneza wowonera.
Moni, ndine Kim, mayi komanso wokonda kuyimitsa zoyenda komanso wodziwa zambiri pakupanga media komanso kakulidwe ka intaneti. Ndili ndi chikhumbo chachikulu chojambula ndi makanema ojambula, ndipo tsopano ndikudumphira molunjika kudziko loyimitsa. Ndi blog yanga, ndikugawana zomwe ndaphunzira ndi inu anyamata.
