Izindlela Elula Zokuthuthukisa Ukukhanyisa Izithombe Zakho ze-3D nezithombe
Ngibheke inkomba eminingi ekhuluma ngokukhanyisa kamuva, futhi ngathola ithuba lokubuka inkulumo kaGnomon Masterclass ku-Efficient Cinematic Lighting noJeremy Vickery (okwamanje usebenza njengomqondisi wezobuchwepheshe e-Pixar).
Ngilandela ubuciko bukaJeremy iminyaka eminingi. Unesitayela esihle kakhulu, esicabanga, futhi wayengomunye wabaculi bokuqala engangikulandela ku-DeviantArt (cishe eminyakeni emine noma emihlanu eyedlule).
Ngiphinde ngithatha ngokujulile ukubuka ngokubheka incwadi yesibili kaJakobe Gurney, Umbala noKhanya.
Ngisho noma basebenza emidlalweni ehlukene, uJames noJeremy babonakala behlanganyela nefilosofi efanayo efana nokukhanya-okuwukuthi, leso senzakalo sokukhanyisa kufanele sibhekiswe ngokuhlaziya, kodwa ukuthi lo mculi kufanele azi nokuthi imiphi imigomo kanye nemibono ingaphulwa noma ikhutshwe ukuze yengeze kanye nesithakazelo.
I-masterclass kaJeremy nencwadi kaGurney bobabili banikeza izeluleko eziningi ezinhle zokudala ukukhanya okusebenzayo ekubunjweni.
Ngizame ukwephula amanye amaphuzu abo amakhulu ukukudlulisela kuwe ukuze usebenzise isithombe se-3D.

Qondisisa Ukusebenza Okukhanyayo Okuphumelelayo 3
Ukukhanyisa okuyizintathu kuyindlela ejwayelekile kunazo zonke yokubonisa ukukhanya kwe-cinema, futhi kuyinto okudingeka uyiqonde ngempela ukudala imifanekiso ye-CG ephumelelayo.
Ngeke ngiye emininingwaneni eminingi lapha, kodwa ukucushwa kokuqala kokukhanyisa okuyi-3 kuzofanela okufana nalokhu okulandelayo:
- Ukukhanya okuKhiye - Umthombo wokukhanya oyinhloko, uvame ukubeka ama-degree angu-45 ngaphambili nangaphezulu kwesihloko.
- Ukugcwalisa Ukukhanya - Ukugcwalisa (noma ukukhahlela) kukhanya umthombo wokukhanya wesibili ongcono osetshenziselwa ukukhanyisa izindawo zethunzi zokwakheka. Ukugcwaliswa kuvame ukubekwe eceleni kwesihluthulelo.
- Ukukhanya kwe-Rim - Ukukhanya komkhonto umthombo oqinile, okhanyayo okhanyayo esihlokweni esivela ngemuva, ovame ukuhlukanisa isihloko kusuka kumlando wakudala ngokudala uhlaka oluncane lokukhanya eceleni kwesihloko sendaba.

Amachibi okukhanya
Lapho uJeremy Vickery eqala ukukhuluma ngale nqubo esikoleni sakhe sobuchwepheshe, ngase ngingazicabangi kabili ngalokhu, kodwa njengoba ngangiqala ukubuka ubuciko obuningi be-digital ngokukhanyisa engqondweni, kwenzeka kimi ukuthi ubuchwepheshe banjani (futhi busebenza). kuyinto, ikakhulukazi emasimini.
Abadlali be-Digital landscape basebenzisa "amachibi wokukhanya" cishe becindezela ukwengeza idrama nesithakazelo esiteshini. Hlola lo mdwebo omuhle nguVictor Hugo, futhi unake indlela asebenzisa ngayo igumbi eligxilile lokukhanya okukhanyayo ukwengeza idrama esithombeni.
Abadwebi abaningi base-Hudson River School basebenzisa amasu afanayo.
Ukukhanya emvelweni akuvamile ukuba njalo futhi kufane, futhi akusizi neze ukugwedla. Enkulumweni kaJeremy, uthi umgomo wakhe njengomculi awuyikudala kabusha iqiniso, kungcono ukwenza into engcono. "Ngiyavuma ngenhliziyo yonke.

Ukubheka kwezulu
Lena enye inqubo ewusizo ngokuphawulekayo kumvelo abaculi abadinga ukudala umqondo wokujula kwezithombe zabo.
Iningi labaqalayo benza iphutha lokusebenzisa ukukhanyisa okuqhubekayo nombala wonke kulo lonke indawo yabo. Eqinisweni, njengoba izinto zihamba kude nekhamera, kufanele zifake futhi zenzeke ngemuva.
Izinto ezikude kufanele zibe neminye yamanani amnyama kakhulu endaweni yesehlakalo. Emaphakathi-mhlaba kufanele ibe nephuzu elibalulekile, likhanyiswe ngokufanele, nezinto ezikude kufanele zifakwe futhi ziguquke zibheke embala wezulu. Ngokuqhubekayo into, okungafani nakancane kufanele kube yindawo yayo.
Nansi umdwebo omangalisayo ogcizelela umbono womkhathi (nokukhanya okuhlanganisiwe) ukuthuthukisa ukujula.

Dlala ngokufudumele ngokumelene ne-Cool
Lena yindlela yobuciko yobuciko, lapho izinto ezikhanyisayo zivame ukuba nezifudumele, kanti izindawo zethunzi zivame ukuhunyushwa nge-blue cast.
I-master fantasy illustrator uDave Rapoza usebenzisa le ndlela ngokuphindaphindiwe emidwebo yakhe.

Sebenzisa ukukhanya okufakiwe
Lena yindlela yokuguqula uGurney noJeremy. Ukukhanya okufakiwe
Kuyindlela ewusizo ngoba inikeza umbukeli umbono wokuthi kukhona izwe ngaphesheya kwemiphetho yefreyimu. Isithunzi esivela emthini ongabonakali noma iwindi ayengeze nje kuphela ukuthi ungeza izakhiwo ezithakazelisayo esithombeni sakho, futhi kusiza ukudonsa izithameli zakho futhi uzicwilise emhlabeni ozama ukuyidala.
Ukusebenzisa umthombo wokukhanya ophikisiwe ovimbekile ekubukelweni kwezilaleli kuyisicoco sokuqala sokuhlakulela umqondo wemfihlakalo noma ukubuza. Le nqubo yayisetshenziswe ngokujulile kokubili i- Pulp Fiction neRepo Man

Hlukanisa Ukubunjwa Kwesibili
Ukuhlukanisa okwesibini kubaluleke kakhulu uma ukhanyisa izithombe noma imifanekiso ebukwayo. Ephawulwe ngokukhululekile, i-Vickery yenza ngokuyisisekelo isitatimende esilandelayo ekufundeni kwakhe kwe-Gnomon:
"Ifilimu ayifani nobuciko obuhle, ngomqondo wokuthi izethameli ngeke zithole ithuba lokuma egalari futhi zibuke isithombe ngasinye ngabanye imizuzu emihlanu. Izibhamu eziningi azihlali isikhathi esingaphezu kwamasekhondi amabili, ngakho-ke qiniseka ukuthi usebenzisa ukukhanya kwakho ukuze udale indawo eqondile eqondile esikhwameni ngokushesha. "
Futhi, iningi lalelo catshulwa lichazwe ngamagama ami, kodwa iphuzu eliyisisekelo azama ukukwenza ukuthi yi-ifilimu ne-animation awunawo isikhathi esiningi sithombe sakho ukwenza umqondo.
