Chromakey: Wehe i ke kua a me ka pale ʻōmaʻomaʻo vs ka pale ʻulaʻula
Hoʻohana nui ʻia nā hopena kūikawā i nā kiʻiʻoniʻoni, series a me nā hana pōkole. Ma kahi o nā hopena kikohoʻe, ʻo ia nā noi maʻalahi i hoʻohana nui ʻia, e like me Chromakey.
ʻO kēia ke ʻano o ka hoʻololi ʻana i ke kua (a i kekahi mau ʻāpana ʻē aʻe) o ke kiʻi me kahi kiʻi ʻē aʻe.
Hiki i kēia ke hele mai kahi kanaka i loko o ke keena e kū koke ana i mua o kahi pyramid ma ʻAigupita, i kahi kaua ākea nui ma kahi honua mamao.
Ma kēia pou e uhi mākou:
He aha ka Chromakey?
ʻO ka haku mele Chroma kī, a i ʻole ke kī chroma, he hopena kūikawā / hana hope-hana no ka haku mele ʻana (layering) ʻelua kiʻi a i ʻole nā kahawai wikiō i hui pū ʻia ma muli o nā kala kala (chroma range).
Ua hoʻohana nui ʻia ka ʻenehana ma nā kahua he nui e wehe i kahi kāʻei kua mai ke kumuhana o kahi kiʻi a wikiō paha - ʻo ia hoʻi ka nūhou, nā kiʻi ʻoniʻoni a me nā ʻoihana wikiō.
Hana ʻia ke ʻano waihoʻoluʻu o ka papa luna i akaka, e hōʻike ana i kekahi kiʻi ma hope. Hoʻohana mau ʻia ka ʻenehana kī chroma i ka hana wikiō a me ka hana hope.
Ua kapa ʻia kēia ʻano hana he kī kala, uhi hoʻokaʻawale kala (CSO; ma mua o ka BBC), a i ʻole ma nā ʻōlelo like ʻole no nā ʻano like ʻole e pili ana i ka waihoʻoluʻu e like me ka pale ʻōmaʻomaʻo, a pale polū.
Hiki ke hana ʻia ke kī ʻana o Chroma me nā kāʻei o nā kala like ʻole a ʻokoʻa, akā ʻoi aku ka maʻamau o ka ʻōmaʻomaʻo a me ka uliuli no ka mea ʻokoʻa loa lākou i ka hue mai ka nui o nā kala ʻili kanaka.
ʻAʻohe wahi o ke kumuhana i paʻi ʻia a paʻi kiʻi ʻia paha ke kope kope i kahi kala i hoʻohana ʻia ma ke kua.
ʻO ka koho mua āu e hana ai ma ke ʻano he mea hana kiʻiʻoniʻoni Green paku a i ʻole ka Pale Blue.
E hoʻomaka me kāu mau papa moʻolelo hoʻomaha
E kau inoa i kā mākou nūpepa a loaʻa i kāu hoʻoiho manuahi me ʻekolu papa moʻolelo. E hoʻomaka me ka lawe ola ʻana i kāu mau moʻolelo!
E hoʻohana wale mākou i kāu leka uila no kā mākou leka uila a mahalo iā ʻoe pilikino
He aha nā ikaika o kēlā me kēia kala, a he aha ke ala kūpono i kāu hana?
ʻO ka uliuli a me ka ʻōmaʻomaʻo nā kala ʻaʻole i loaʻa i ka ʻili, no laila ua kūpono lākou i nā kānaka.
Ke koho ʻana i nā lole a me nā mea ʻē aʻe i ke kiʻi, pono ʻoe e hoʻolohe ʻaʻole hoʻohana ʻia ke kala kī chroma.
Paʻi Polū Chroma Key
ʻO kēia ke kala kī chroma kuʻuna. ʻAʻole ʻike ʻia ka waihoʻoluʻu i ka ʻili a hāʻawi i ka "color spill" liʻiliʻi e hiki ai iā ʻoe ke hana i kahi kī maʻemaʻe a paʻa.
Ma nā hiʻohiʻona i ke ahiahi, nalo pinepine nā hewa i ka ʻulaʻula, hiki ke lilo i mea pono.
ʻO ka pale ʻōmaʻomaʻo Chromakey
Ua lilo ka'ōmaʻomaʻo'ōmaʻomaʻo i mea kaulana i nā makahiki, ma muli o ka piʻiʻana o ke wikiō. Loaʻa ke kukui keʻokeʻo no ka 2/3 o ke kukui ʻōmaʻomaʻo a no laila hiki ke hana maikaʻi ʻia e nā ʻāpana kiʻi i nā kiʻi paʻi kiʻi.
Ma muli o ke kukui, ʻoi aku ka nui o ka "color spill", ʻoi aku ka maikaʻi o ka pale ʻana i kēia ma ka mālama ʻana i nā kumuhana i kahi mamao loa mai ka pale ʻōmaʻomaʻo.
A inā hoʻokomo kāu cast i nā jeans polū, ua koho koke ʻia ke koho…
ʻO ke ʻano o ke ʻano āu e hoʻohana ai, he mea nui ke kukui ʻole me ke aka. Pono ka waihoʻoluʻu e like me ka hiki, a ʻaʻole pono e ʻālohilohi a wīwī paha ka mea.
ʻO kahi mamao nui me ka hohonu palena palena e hoʻoheheʻe i nā wrinkles ʻike ʻia a me ka fluff.
E hoʻohana i nā polokalamu chromakey maikaʻi e like me Primatte a i ʻole Keylight, keyers in polokalamu hoʻoponopono wikiō (e nānā i kēia mau koho) waiho pinepine i kahi mea e makemake ai.
ʻOiai ʻaʻole ʻoe e hana i nā kiʻiʻoniʻoni hana nui, hiki iā ʻoe ke hoʻomaka me ka chromakey. Hiki ke lilo i kumu kūʻai kūpono, inā hoʻohana ʻia me ke akamai a ʻaʻole hoʻopilikia i ka mea nānā.
