Imani Motion Lighting 101: Momwe Mungagwiritsire Ntchito Nyali Pamakonzedwe Anu

pa kim Zasinthidwa: July 2, 2022

Chithunzi chopanda kuwonekera ndi chithunzi chakuda, ndizosavuta. Ziribe kanthu momwe kamera yanu ilili yopepuka bwanji, nthawi zonse mumafunika kuwala kuti mujambule zithunzi.

Pali kusiyana kwakukulu pakati pa kuunikira ndi kuunikira.

ndi Kuunikira, pali kuwala kokwanira kujambula chithunzi; ndi kuunikira mutha kugwiritsa ntchito kuwala kuti mudziwe malo kapena kufotokoza nkhani.

Ndicho chida champhamvu kwambiri padziko lapansi kuyimilira mayendedwe kanema!

Malangizo owunikira kuti mupange filimu yoyimitsa bwino

Nyali zitatu

Ndi nyali zitatu mutha kupanga mawonekedwe okongola. Njira imeneyi imagwiritsidwa ntchito nthawi zambiri pazokambirana.

Choyamba, muli ndi nyali kumbali imodzi ya phunziro, kuwala kofunikira kuti muwunikire mokwanira phunzirolo.

Kumeneko nthawi zambiri kumakhala kuwala kolunjika. Kumbali inayi ndi kuwala kodzaza kuti mupewe mithunzi yowopsya, izi nthawi zambiri zimakhala zosalunjika.

Kuunikira kumbuyo kumayikidwa kumbuyo kuti alekanitse nkhaniyo kuchokera kumbuyo.

Kuwala kumbuyoko nthawi zambiri kumakhala kumbali, komwe kumakupatsani m'mphepete mwa kuwala komwe kumazungulira munthu.

• Sikoyenera kuyika nyali yodzaza mbali inayo, izi zitha kubwera kuchokera mbali imodzi mosiyanasiyana.

Kuwala kolimba kapena kuwala kofewa

Mukhoza kusankha kalembedwe pazochitika, nthawi zambiri mtundu wa kuyatsa umasankhidwa pakupanga konse.

Mu kuwala kolimba, nyali zimayang'ana mwachindunji pamutu kapena malo, mu kuwala kofewa amagwiritsa ntchito kuwala kosalunjika kapena kuwala ndi frost frost frost frost frost frost frost frost frost.

Kuwala kolimba kumatulutsa mithunzi yoopsa komanso yosiyana. Zimabwera molunjika komanso zotsutsana.

Ngati kupanga kwanu kumachitika m'chilimwe ndi kuwala kwa dzuwa, ndizomveka kusankhanso kuwala kolimba pamene mukuwombera m'nyumba kuti mupitirizebe ndi zochitika zakunja.

Kuwala kofewa kumapanga mawonekedwe amlengalenga komanso maloto. Chithunzicho ndi chakuthwa koma kuwala kofewa kumapangitsa zonse kuyenda pamodzi. Zikuonetsa chikondi.

Kuwala kokhazikika

Ngakhale mutagwiritsa ntchito nyali zamakanema, muyenera kuganizira za mawonekedwe anu.

Ngati mu kuwombera kwathunthu pali nyali ya tebulo kumanzere, pafupi-pafupi muyenera kuonetsetsa kuti gwero lalikulu la kuwala limachokera kumanzere.

Ngati muli kujambula kutsogolo kwa chophimba chobiriwira, onetsetsani kuti kuwonekera kwa mutuwo kumagwirizana ndi kuwonekera kwa maziko omwe adzawonjezedwa mtsogolo.

Kuwala kwamitundu

Buluu ndi wozizira, lalanje ndi wofunda, wofiira ndi woopsa. Ndi mtundu mumapereka tanthauzo pazochitikazo. Gwiritsani ntchito bwino zimenezo.

Kusiyanitsa kumanzere ndi kumanja kumagwira ntchito bwino m'mafilimu ochitapo kanthu, buluu kumbali imodzi ndi lalanje mbali inayo. Mukuwona kuti nthawi zambiri, maso athu amapeza kuphatikiza kosangalatsa kuyang'ana.

Kuwala kochulukirapo, mwayi wochulukirapo

Kamera yosamva kuwala ndi yothandiza, koma sikuwonjezera zambiri pazaluso.

Pokhapokha mutasankha kuwala kwachilengedwe, monga momwe amachitira ndi mafilimu a Dogme a m'ma 1990, kuwala kochita kupanga kumakupatsani mwayi wofotokozera bwino nkhani yanu.

Momwe mumawunikira otchulidwa amatha kufotokozera nkhani yonse, mutha kusankha magawo omwe ali pachithunzichi omwe awonekere kapena ayi.

Njira Yopita ku Chidziwitso

Kuyesa ndi kuwala pamaseti amakanema ndi njira yabwino yopititsira patsogolo luso lanu.

Kodi mutha kuyimitsa ndi magetsi a LED?

Zakhala zotchuka padziko lonse lapansi loyimitsa bajeti kwakanthawi, akatswiri akusinthanso nyali za LED pamakanema ndi makanema.

Kodi chimenecho ndi chitukuko chabwino kapena tiyenera kumamatira ndi nyali zakale?

Samalani ndi ma dimmers

Ndizosavuta ngati mutha kuyimitsa nyali za LED, ngakhale ndi nyali zotsika mtengo nthawi zambiri pamakhala batani la dimmer. Koma ma dimmers amenewo amatha kupangitsa kuti kuwala kuzizire.

Pamene ma LED akuzimiririka kwambiri, m'pamenenso amathwanima. Vuto ndilakuti, ndizovuta kuzindikira pomwe kamera imatengedwa ndi flicker.

Ngati mutadziwa pambuyo pake panthawi yokonza, nthawi yatha. Ndicho chifukwa chake kuli kwanzeru kuyesa ma dimmers pasadakhale.

Pangani kuwombera koyesa ndi filimu yokhala ndi masinthidwe osiyanasiyana a dimmer ndikuwunikanso zojambulazo.

Ngati simukudziwa, ndibwino kuti musagwiritse ntchito dimmer ndikusuntha kapena kuzungulira gwero la kuwala.

Pali nyali za LED zokhala ndi masiwichi omwe amakulolani kusankha angati omwe amayatsa nthawi imodzi.

Tiyerekeze kuti pali mamembala 100 onse. Ndiye mutha kusintha pakati pa 25, 50 kapena 100 Leds nthawi imodzi.

Izi nthawi zambiri zimagwira ntchito bwino kuposa kugwiritsa ntchito dimmer. Nthawi zonse, ndi bwino kuyang'ana zoyera musanajambule.

Gwiritsani ntchito Softbox

Kuwala kochokera ku nyali za LED nthawi zambiri kumakhala kovuta komanso "kotsika mtengo".

Poyika bokosi lofewa kutsogolo kwa nyali, mumapangitsa kuwalako kufalikira, komwe nthawi yomweyo kumawoneka bwino kwambiri.

Izi zimapangitsa kuti zikhale zosiyana ndi zowunikira zachikhalidwe, koma kufunikira kwa bokosi lofewa lokhala ndi nyali za LED ndikokulirapo.

Chifukwa nyali za LED zimatentha pang'ono, mutha kusinthanso ndi nsalu kapena pepala ngati mulibe bokosi lofewa pafupi.

Otetezeka komanso omasuka

Zimagwirizana ndi mfundo yapitayi koma zikhoza kutchulidwa mosiyana; Nyali za LED ndizosangalatsa kugwira ntchito.

Nyumbayo imakhala yophatikizika kwambiri, yomwe imakulolani kuti musunge malo ambiri pakanthawi kochepa.

Zimakhalanso zosavuta kunja ngati mungathe kugwirizanitsa bokosi lalikulu la kuwala ndi nyali yaing'ono ya LED ndi batire.

Chifukwa kuyatsa kwa LED kumapangitsa kutentha pang'ono, nawonso ndi otetezeka kwambiri kugwiritsa ntchito.

Osatchulanso zingwe zomwe sizimamwazika pansi mowopsa komanso kugwiritsa ntchito magetsi panja pamvula yamvula…

Sankhani kutentha kwamtundu woyenera

Masiku ano, mutha kugula ma LED okhala ndi kutentha kwamtundu winawake. Amatchulidwa kuti Kelvin (K). Dziwani kuti mutha kusintha kutentha ndi ma dimmers.

Pali nyali za LED zokhala ndi ma LED ozizira komanso otentha omwe mutha kuyatsa kapena kuyatsa padera. Mwanjira imeneyo simusowa kusintha mababu.

Nyalizi zimakhala ndi malo okulirapo chifukwa cha mizere iwiri ya mizere ya LED.

Muyenera kumvetsera kwambiri nyali za LED komwe mungathe kusintha kutentha kwa mtundu. Ngati muwongolera kutentha kwamtundu ndi kuwombera kulikonse, pali mwayi woti kuwomberako sikungafanane bwino.

Ndiye kuwombera kulikonse mu positi kumayenera kusinthidwa, zomwe zingatenge nthawi yambiri.

CRI mtundu mtundu

CRI imayimira Color Rendering Index ndipo imasiyana pakati pa 0 - 100. Kodi gulu la LED lomwe lili ndi mtengo wapamwamba kwambiri wa CRI ndilo kusankha bwino kwambiri?

Ayi, palinso zinthu zina zofunika, koma ganizirani posankha gulu la LED.

Kufananiza; Dzuwa (kwa ambiri gwero lowala kwambiri) lili ndi mtengo wa CRI wa 100 ndipo nyali za tungsten zimakhala ndi mtengo wozungulira 100.

Malangizo ndikusankha gulu lomwe lili ndi mtengo (wowonjezera) wa CRI pafupifupi 92 kapena kupitilira apo. Ngati mukugulitsa mapanelo a LED, yang'anani mitundu iyi:

Si nyali zonse za LED zolimba

Nyali zakale za studio zinkagwiritsa ntchito zitsulo zambiri, zolemera komanso zolimba. Zinayenera kutero chifukwa chakuti apo ayi, nyaliyo idzasungunuka.

Nyali za LED nthawi zambiri zimapangidwa ndi pulasitiki, zomwe zimakhala zopepuka kwambiri kuvala, koma nthawi zambiri zimakhala zosalimba.

Izi ndizowona, pulasitiki imawoneka yotsika mtengo, koma ndi nyali zotsika mtengo zimatha kuchitika kuti nyumbayo imang'ambika mofulumira pamene ikugwa kapena panthawi yoyendetsa.

Ndalamazo ndi zapamwamba

Pali nyali za bajeti za LED za makumi angapo, zomwe ndizotsika mtengo kwambiri sichoncho?

Ngati mukufanizira ndi kuyatsa kwa studio, inde, koma nyali zotsika mtengo ndizokwera mtengo kwambiri kuposa nyali yomanga, muyenera kuzifanizira ndi izo.

Nyali zapamwamba, zapamwamba za LED ndizokwera mtengo kwambiri kuposa nyali zachikhalidwe. Mumapulumutsa pang'ono magetsi, mwayi waukulu kwambiri ndi moyo wautali komanso kugwiritsa ntchito nyali za LED mosavuta.

Chiwerengero cha maola oyaka ndi okwera kwambiri, pamlingo wabwino mumalipira zochepa pakuwunikira kwa LED, bola ngati simukuwagwetsa!

Ngati simungathe kusankha…

Pali nyali zama studio pamsika zomwe zimakhala ndi nyali wamba kuphatikiza ndi kuyatsa kwa LED. Kwenikweni, izi zimakupatsani ubwino wa machitidwe onse awiri.

Mutha kunena kuti muli ndi zovuta zonse ziwiri. Ambiri

Nthawi zina ndi bwino kusankha dongosolo limodzi.

Kodi muyenera kusankha kuyatsa kwa LED kuti muyime?

Kwenikweni, pali zabwino zambiri kuposa kuipa. Wojambula mavidiyo akale angakonde kugwira ntchito ndi nyali "zabwino" za tungsten, koma ndizokhazikika.

Pafupifupi nthawi zonse, kuyatsa kwa LED kumapereka zabwino zambiri kuposa zovuta. Mwachitsanzo, tengani zochitika izi:

Mkati pabalaza

Mukufunikira malo ochepa, pali chitukuko chochepa cha kutentha, ndi mabatire monga gwero la mphamvu, palibe zingwe zotayirira pansi.

Kunja kumunda

Simukusowa jenereta yomwe imapanga phokoso lambiri, nyali ndizophatikizana komanso zosavuta kunyamula, palinso nyali za LED zomwe zimakhala (splash) zopanda madzi.

Pa kanema wotsekedwa

Mumapulumutsa mphamvu, mutha kusinthana mosavuta pakati pa kutentha kwamtundu ndipo nyali zimatha nthawi yayitali, kotero kusinthanitsa sikuli kofunikira.

Bajeti kapena Premium LED?

Nkhani ya kutentha kwamtundu, makamaka kuphatikiza ndi ma dimmers, ndi chifukwa chofunikira kuyika ndalama mu nyali zaukadaulo za LED. Pangani chigamulo chodziwitsidwa musanasankhe chizindikiro kapena mtundu wina wa nyali.

Kodi ndi njira yobwereka kapena mukufuna kugula nokha nyali? Moyo wautali wa nyali za LED umapangitsa kukhala ndalama zabwino kwa nthawi yayitali. Ndipo inu mumadziwa nyali zanu.

Ngati mwaganiza zobwereketsa, ndikwanzeru kuti muyambe kujambula zingapo zoyeserera ndikuziwona pa chowunikira.

Monga momwe muyenera kuphunzira kugwiritsa ntchito kamera, muyeneranso kudziwa ins ndi kutuluka kwa nyali (ngati mulibe gaffer yomwe muli nayo;)).

Kutsiliza

Kuti mukhazikitse maziko olimba mutha kugula Experience Lighting Masterclass ndi illumination Cinematography Workshop (kudzera kutsitsa kwa digito) kuchokera kwa katswiri waku Hollywood Shane Hurlbut.

Maphunzirowa amapereka chithunzi chabwino kwambiri cha momwe mungasonyezere "zenizeni" za mafilimu a Hollywood ndi chirichonse chomwe chimabwera ndi izo. Ngati mulibe chidziwitso chochepa ndi kuwala, ndithudi ndi bwino kufufuza.

Ndi ndalama ndithu koma zidzatengera chidziwitso chanu pa mlingo wapamwamba.

Tsoka ilo, kuyatsa nthawi zambiri sikumanyalanyazidwa mu bajeti yaying'ono/zopanga za indie.

Chifukwa chake nsonga: m'malo mwa Arri Alexa, lekani kamera yaying'ono ndi kuwala kowonjezera pang'ono kuti mupeze zotsatira zabwino! Chifukwa kuwala ndi chinthu chofunikira kwambiri mufilimu.

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.
