Iyi ndiyo nzira yekutsiva kumashure (uye dzimwe nguva zvimwe zvikamu) zvemufananidzo nemumwe mufananidzo.
Izvi zvinogona kubva kumunhu ari mu studio kamwe kamwe akamira pamberi pepiramidhi muEgypt, kuenda kuhondo huru yemuchadenga papasi riri kure.
Mune ino posvo isu tichafukidza:
Chii chinonzi Chromakey?
Chroma kiyi compositing, kana chroma keying, yakasarudzika mhedzisiro / post-yekugadzira nzira yekugadzira (layer) mifananidzo miviri kana vhidhiyo hova pamwe chete zvichienderana neruvara hues (chroma renji).
Iyo tekinoroji yakashandiswa zvakanyanya muminda yakawanda kubvisa kumashure kubva pachinyorwa chemufananidzo kana vhidhiyo - kunyanya yenhau, inofambisa mifananidzo uye vhidhiyo yemitambo maindasitiri.
Rudzi rwemavara muchikamu chepamusoro chinoitwa pachena, zvichiburitsa mumwe mufananidzo kumashure. Iyo chroma keying tekinoroji inowanzo shandiswa mukugadzira vhidhiyo uye post-kugadzirwa.
Iyi nzira inonziwo color keying, color-separation overlay (CSO; kunyanya neBBC), kana nemashoko akasiyana-siyana akasiyana-siyana ane hukama neruvara segirinhi regirini, uye. yebhuruu sikirini.
Chroma keying inogona kuitwa nekumashure kwechero ruvara rwuri yunifomu uye rwakasiyana, asi girinhi nebhuruu mabviro anonyanya kushandiswa nekuti anosiyana zvakanyanya muhue kubva kune mazhinji eganda remunhu.
Hapana chikamu chenyaya chiri kutorwa foto kana kutorwa chinokwanisa kutevedzera ruvara rwakashandiswa kumashure.
