Ukuqoshwa Kwevidiyo Ehamba Kancane Ngamakhamera Edijithali: Ubuchwepheshe Nobuciko Enkathini Yanamuhla
Ubuchwepheshe bokuqopha amavidiyo buthuthuke ngokushesha emashumini eminyaka amuva nje. Esinye isici esiye sathandwa kakhulu futhi safunwa kakhulu ukuqopha ividiyo ehamba kancane. Lobu buchwepheshe busenza sikwazi ukuthwebula izikhathi ezihamba kancane, sidale imiphumela emangalisayo yedrama nobuciko. Lesi sihloko sizohlola ukuthi amakhamera edijithali anamuhla avumela kanjani ukuqopha ividiyo ehamba kancane, ubuchwepheshe obusemuva kwayo, kanye nemibono yokudala yokuyisebenzisa emikhiqizweni eyahlukahlukene.
Umlando Omfushane Wokuhamba Kancane
Ngaphambi kokuba siqhubekele phambili, kuyasiza ukufunda okuncane ngomlando wokuqoshwa kwevidiyo ehamba kancane. Ukusetshenziswa kokunyakaza kancane kumafilimu namavidiyo kungalandelelwa emuva ekuqaleni kwekhulu lama-20. U-Ernst Mach, isazi sefiziksi nesazi sefilosofi sase-Austria, waziwa njengomunye wabaqalayo ekusebenziseni amasu okunyakaza kancane ukuhlaziya ukunyakaza kwama-projectiles. Ngemuva kwalokho, u-Eugène Lauste, umsunguli waseFrance, wadala ikhamera yokuqala yesithombe esisheshayo cishe ngo-1912.
Kodwa-ke, ukusetshenziswa kwalobu buchwepheshe embonini yamafilimu kwaqala ngempela maphakathi nekhulu lama-20. Abaqondisi bamafilimu abanjengo-Akira Kurosawa noStanley Kubrick babevame ukusebenzisa amasu okunyakaza kancane ukuze bangeze idrama nokuqina ezigcawini zabo. Ngokuthuthuka kwamakhamera edijithali ayinkimbinkimbi ngokwengeziwe, ukuqoshwa kokunyakaza kancane sekufinyeleleka kalula futhi kwathandwa kakhulu phakathi kwabathwebuli bezithombe namavidiyo abasafufusa nabangochwepheshe.
Ubuchwepheshe Obusekela Ukuqopha Okuhamba Kancane
Empeleni, amavidiyo e-slow-mo adalwe ngokuqopha ividiyo ngesivinini sohlaka esiphezulu kakhulu kunejwayelekile. Ngokwejwayelekile, amavidiyo aqoshwa kumafreyimu angu-24 noma angu-30 ngomzuzwana (fps). Kodwa-ke, ekuqopheni kwe-slow-mo, leli nani lingakhuphuka liye kumakhulu, ngisho nezinkulungwane zamafreyimu ngomzuzwana. Uma amavidiyo aqoshwe ngaleli sivinini sohlaka esiphezulu edlalwa ngesivinini esijwayelekile, umphumela uba ukunyakaza okuncishisiwe.
Nazi ezinye izingxenye ezibalulekile kubuchwepheshe bokuqopha be-slow-mo:
Inzwa Yesithombe kanye Neprosesa
Inzwa yekhamera kanye neprosesa yesithombe zidlala indima ebalulekile ekuqopheni okuhamba kancane. Inzwa enesivinini esikhulu sokufunda kanye namakhono okucubungula idatha asheshayo iyadingeka ukuze kuthwetshulwe izithombe ngamanani aphezulu ozimele. Amanye amakhamera edijithali anamuhla asebenzisa izinzwa ze-CMOS ezinobuchwepheshe bokuvala bomhlaba wonke ukunciphisa ukuphazamiseka kokunyakaza.
Isitoreji Sedatha
Ukuqopha ividiyo ngamanani aphezulu ozimele kukhiqiza inani elikhulu ledatha ngesikhathi esifushane. Ngakho-ke, ikhadi lememori elinesivinini esikhulu sokubhala libalulekile ukuqinisekisa ukuthi wonke ozimele aqoshwa kahle ngaphandle kwanoma yimaphi ozimele angase onakalise ividiyo. Amafomethi okugcina njenge-ProRes noma i-RAW avame ukusetshenziswa lapho kuqoshwa ividiyo ehamba kancane ukuze kulondolozwe ikhwalithi yesithombe ephezulu.
I-Algorithm Yokucubungula Ividiyo
Ngemva kokuba isithombe sithathwe yinzwa, ama-algorithm okucubungula ividiyo kuphrosesa yesithombe adlala indima ebalulekile ekucindezeleni nasekuhleleni idatha. Lawa ma-algorithm kumele akwazi ukucubungula idatha ngokushesha ukuze agweme ukubambezeleka futhi aqinisekise ukuthi ividiyo yekhwalithi ephezulu iyakhiqizwa.
Izinhlelo Zokusebenza Zevidiyo Ezihamba Kancane Zokudala
Ividiyo ye-slow-mo ayigcini nje ngokunciphisa ijubane lokunyakaza; imayelana nokuveza ubuhle, imininingwane, kanye nokuguquguquka okungaba nzima ukukuthatha ngevidiyo yendabuko. Nazi ezinye izinhlelo zokusebenza zokudala zevidiyo ye-slow-mo ongazizama:
Izigcawu Zesenzo
Ekukhiqizweni kwamavidiyo efilimu noma omculo, izigcawu zesenzo zivame ukudutshulwa nge-slow-mo ukuze kwengezwe ubukhali kanye nedrama. Ukunyakaza okusheshayo njengokuqhuma, ukukhahlela, noma ukugxuma kubonakala kucacile futhi kunemininingwane eminingi uma kudutshulwa nge-slow-mo, okuvumela ababukeli ukuthi baqonde kangcono indlela yokudweba kanye nemiphumela ekhethekile esetshenzisiwe.
Amavidiyo Ezemidlalo
Ezemidlalo zingenye indawo lapho ukuqopha okuhamba kancane kusebenza kahle kakhulu. Abasubathi abagijima, abagxumayo, noma abenza ukunyakaza okuchwepheshile kakhulu bangahlaziywa futhi baziswa kangcono ngevidiyo ye-slow-mo. I-Slow-mo isivumela ukubona isicathulo somgijimi sithinta ithrekhi noma i-basketball indiza emoyeni ibheke endaweni ezungezile ngemininingwane emangalisayo.
Imibhalo Yemvelo
Indawo yonke igcwele ubuhle obuvame ukungabonakali emehlweni omuntu ngesivinini esijwayelekile. Izithombe ze-slow-mo zisivumela ukuthi sithwebule izikhathi zemvelo njengezinyoni ezindizayo, amaconsi amanzi awelayo, noma izinambuzane ezindizayo ngezindlela ezimangalisayo ngempela. Ividiyo ye-slow-mo yenza izinto ezivamile zibonakale zingavamile.
Umsebenzi Wobuciko Omfushane
Abathwebuli bevidiyo nabaculi bavame ukusebenzisa amasu e-slow-mo ukudala ubuciko obubonakalayo obungabonakali. Ukusebenzisa i-slow-mo ezindaweni zokudala njengokuxuba upende, ukukhanya okukhethekile, noma ukusebenzisana phakathi kwezinto ezahlukene kungadala imiphumela ebonakalayo ethakazelisayo neyingqayizivele.
Ukuhlolwa Kwesayensi
Njengoba nje ososayensi babesebenzisa i-slow-mo ukuhlaziya izinhlamvu ezinsukwini zokuqala, lobu buchwepheshe busetshenziswa nasezivivinyweni zesayensi zanamuhla. Besebenzisa ividiyo ye-slow-mo, ososayensi bangafunda futhi bahlaziye izenzakalo ezenzeka ngama-millisecond, njengokusabela kwamakhemikhali, ukushayisana kwezinto, noma ukunyakaza kwezinhlayiya.
Amathiphu Okuqopha Nge-Slow-Mo
Kulabo abanesifiso sokuzama ukuqopha kancane kancane, nanka amanye amathiphu angakusiza ukuthola imiphumela emihle kakhulu:
Khetha Ikhamera Efanele
Akuwona wonke amakhamera edijithali asekela ukuqoshwa kwevidiyo okuhamba kancane. Qiniseka ukuthi ikhamera yakho iyakwazi ukuqopha ngesivinini esiphezulu sozimele. Amanye amakhamera adumile okuqopha okuhamba kancane yi-Sony RX100, i-GoPro Hero, nama-iPhone anekhono lokuhamba kancane.
Ukuzinza Kwekhamera
Ukuzinza kubalulekile ekudubuleni okuhamba kancane. Noma yikuphi ukunyakaza kwesandla noma ikhamera eqhaqhazelayo kuzobonakala kakhulu ku-footage ye-mo-slow. Sebenzisa i-tripod noma i-gimbal ukuqinisekisa ukuzinza.
Ukukhanya Okwanele
Ukurekhoda ngamaza aphezulu ozimele kudinga ukukhanya okwanele. Ngokuvamile, isivinini se-shutter esisetshenziselwa ukuqopha okuhamba kancane sizoba phezulu, okudinga ukukhanya okwengeziwe ukuze kukhiqizwe isithombe esicacile.
Hlela Indawo Ngokucophelela
Ukuqopha okuhamba kancane akuyona into okufanele ithathwe kalula. Hlela indawo yakho ngokucophelela, naka imininingwane yokunyakaza ofuna ukukuthatha, futhi uqinisekise ukuthi zonke izinto ezidingekayo sezilungile ngaphambi kokuthi uqale ukudubula.
Hlola futhi Udale
Ungesabi ukuzama izilungiselelo ezahlukene kanye nezimo zokukhanya. Zama amazinga ahlukene ozimele kanye nezihloko ukuze ubone ukuthi zikhiqiza miphi imiphumela. Ubuciko buyisihluthulelo sokudala amavidiyo ahehayo futhi ahlukile ahamba kancane.
Ikusasa Lobuchwepheshe Bokurekhoda Nge-Slow-Mo
Ngokuqhubeka kwentuthuko yobuchwepheshe, ikusasa lokuqopha okuhamba kancane libukeka lithembisa kakhulu. Amakhamera anezinga eliphezulu lozimele, ikhwalithi yesithombe engcono, kanye nesitoreji esisebenza kahle kakhulu azoqhubeka nokuthuthukiswa. Ama-algorithms okucubungula amavidiyo nawo azoba yinkimbinkimbi kakhulu, okuvumela imiphumela ebushelelezi nenemininingwane eminingi.
Ngaphezu kwalokho, ubuchwepheshe bobuhlakani bokwenziwa (AI) bungadlala indima ekuthuthukiseni ikhwalithi yokuqoshwa kokunyakaza okuhamba kancane. I-AI ingasetshenziswa ukuzinzisa izithombe, ukunciphisa umsindo, ngisho nokulinganisa idatha engekho ukuze kukhiqizwe amavidiyo ahamba kancane angcono nangokoqobo.
Isiphetho
Ukuqoshwa kwevidiyo ye-slow-mo kulethe inkathi entsha ekuqopheni amavidiyo kanye ne-cinematography. Ngobuchwepheshe obuhlala bushintsha, abadali bangathwebula futhi baveze izikhathi ngendlela engakaze ibonwe ngaphambili. Kusukela esenzweni kanye nezigcawu zezemidlalo kuya kumadokhumentari emvelo kanye nobuciko obungabonakali, i-slow-mo inikeza amandla okudala angenamkhawulo. Ngokuqonda nokusebenzisa ubuchwepheshe obusemuva kokuqoshwa kwe-slow-mo, ungadala amavidiyo angewona amahle futhi amangalisayo kuphela, kodwa futhi agcwele imininingwane kanye nemizwa ejulile.
