Lawula Umbala Wezithombe Zakho nge-Balance Custom Custom
Ukukhanya kunamazinga okushisa ahlukeneyo ombala futhi kuyashintsha nsuku zonke naphakathi kwemithombo yokukhanya yokufakelwa. Ukuqonda ibhalansi emhlophe nendlela yokusebenza ngayo ikhamera ye-DSLR kubalulekile ekususeni umbala ogqamile nokudala imifanekiso emibala emihle.
Ngaphandle kwekhamera, asiqapheli ngokujwayelekile ukuguquka kokushisa kombala. Iso lomuntu lingcono kakhulu ekucubunguleni umbala futhi ubuchopho bethu bungakwazi ukulungisa ukuthi yini okufanele ibe mhlophe endaweni yesehlakalo. Ngakolunye uhlangothi, ikhamera idinga usizo!
Ukushisa kombala
Njengoba kushiwo ngenhla, izikhathi ezihlukene zosuku nemithombo elula zidala amazinga okushisa ahlukahlukene. Ukukhanya kubalwa kuma-kelvini futhi ukukhanya okungathathi hlangothi kukhishwa kuma-5000K (ama-kelvini), okulingana nelanga elikhanyayo nelanga.
Uhlu olulandelayo luyisiqondiso emazingeni okushisa ombala akhiqizwa yimithombo ehlukene yokukhanya.
- 1000-2000K: ikhandlelight
- 2500-3500K: Ukukhanya kwe-Tungsten (i-bulb evamile ye-incandescent house)
- 3000-4000K: I- Sunrise / Sunset (isibhakabhaka esicacile)
- 4000-5000K: Ukukhanya kwe-fluorescent
- 5000-5500K: I- Electronic Flash
- 5000-6500K: Ukukhanya kwelanga (izulu elikhanyayo nelanga elingaphambili)
- 6500-8000K: I- skies edidayo (elinganiselayo)
- 9000-10000K: I- Skies noma i-Shade kakhulu ye-Overcast
Kungani Kubalulekile Ukushisa Umbala?
Esinye sezibonelo ezinhle kakhulu sokulinganisela kombala kanye nomphumela wayo ezithombeni zingabonakala ekhaya elisisebenzisa ama-ampb light-incandescent bulb. Lawa mabani anika ukukhanya okufudumele, okuphuzi okwesibhakabhaka okuthokozisa iso kodwa akusebenzi kahle ngefilimu yombala.
Bheka izithombe ezindala zomndeni kusukela ezinsukwini zefilimu futhi uzobona ukuthi iningi lalabo abangazange balisebenzise i- flash babe ne-hue ephuzi ebopha isithombe sonke. Lokhu kungenxa yokuthi amafilimu amaningi ombala ayalinganiselwe ukukhanya kwelanga futhi, ngaphandle kokuhlunga okhethekile noma ukuphrinta okhethekile, izithombe azikwazanga ukulungiswa ukuze zisuse leso sici esiphuzi.
Ngesikhathi sokudlala izithombe ze-digital, izinto zishintshile . Amakhamera amaningi adijithali, ngisho namafoni ethu, anemodi yokulinganisela embala yemoto. Izama ukulungisa nokukhokhela amazinga okushisa ahlukahlukene kumbala ukuletha ithoni lonke emuva esimweni sokungathathi hlangothi esifana nalokho iso lomuntu elibonayo.
Ikhamera ilungisa ukushisa kombala ngokulinganisa izindawo ezimhlophe (amathrekhi angathathi hlangothi) wesithombe. Isibonelo, uma into emhlophe ine ithoni eliphuzi kusuka ekukhanyeni kwe-tungsten, ikhamera izolungisa ukushisa kombala ukuze kube mhlophe okwedlulayo ngokungeza ngaphezulu iziteshi eziluhlaza okwesibhakabhaka.
Njengoba ubuchwepheshe bubukhulu, ikhamera isenenkinga yokulungisa kahle ibhalansi emhlophe futhi yingakho kubalulekile ukuqonda ukuthi ungasebenzisa kanjani izindlela ezihlukahlukene zamabhalansi ezimhlophe ezitholakala kwi-DSLR.
Izindlela zokulinganisela ezimhlophe
Kuyinto evamile kumakhamera we-DSLR ukufaka izindlela ezihlukahlukene zamabhalansi ezimhlophe ezizokuvumela ukuba ulungise ibhalansi yombala njengoba kudingeka. Amatshwayo asetshenziselwa ngamunye ajwayelekile futhi ajwayelekile phakathi kwawo wonke ama-DSLR (hlola incwadi yakho yekhamera ukuze uzijwayele ngezimpawu).
Ezinye zalezi zindlela zithuthukile kakhulu kunezinye futhi zingadinga ukutadisha okwengeziwe nokuzikhandla. Amanye amamodi yizinto ezilungiselelwe izimo ezivamile zokukhanyisa ezizoshintsha ibhalansi yombala esekelwe izinga lokushisa elilinganiselwe elinikezwe eshadini ngenhla. Umgomo ngamunye ukunciphisa ukushisa kombala emuva kokulinganisela 'kwelanga.'
Amamodi Wokulinganisela Okumhlophe Okumisiwe:
- Ukulinganisela Okumhlophe Okumhlophe (uphawu - AWB) uye phambili kakhulu ekuthembekeni, futhi kufanele isetjhe izinga lokushisa kombala kuzo zonke kodwa izimo zokukhanyisa eziyinkimbinkimbi kakhulu.
- Ukukhanya kwelanga / Ukushisa (uphawu - ilanga elinemibala ekhanyayo) lisetshenziselwa izimo zokukhanyisa 'ezivamile' futhi lilingana nalokho okushiwo amafilimu amaningi ombala.
- Ukushisa (amafu - amatshwayo) kungasetshenziswa ngosuku oludakayo ukuze kuthunjiswe ithoni yombala.
- Umthunzi (indlu engokomfanekiso enezingqimba ezidibeneyo phansi) ifana nesimo sokuthi 'sezulu' futhi singasetshenziselwa ukuhlehlisa ibhalansi yombala uma umuntu engakutholi kahle.
- I-Flash (umcibisholo onama-symbol okhomba phansi) nayo yenzelwe ukwengeza imfudumalo emibala lapho usebenzisa i-flash.
- I-tungsten (isibonakaliso - isibani sebani lomkhaya esinemibala ekhanyayo) singasetshenziswa ngaphakathi endlini ngaphansi kokukhanya kwe-incandescent lapho ibhalansi elimhlophe elimhlophe lingasusanga ngokuphelele i-yellow noma i-orange.
- I-fluorescent (umugqa olinganiselwe olinganiselwe ofana ne-tube fluorescent enezintaba ezikhanyayo) iwusizo emabhizinisini asebenzisa ukukhanya kwe-fluorescent lapho ibhalansi elimhlophe elimhlophe lingasusi luhlaza okwesibhakabhaka noma oluhlaza.
Amamodi Wokulinganisela Okumhlophe Okumhlophe:
- Ukulinganisela Okumhlophe Okumnyama (uphawu - izintathu ezimbili ezihlangothini lwawo ngesikwele phakathi) kuvumela abasebenzisi ukuthi bahlele ibhalansi yabo emhlophe besebenzisa ikhadi elimhlophe (elifundela i-18% elimpunga, iphakathi phakathi kweqiniso elimnyama neliqiniso elimhlophe) noma ikhadi elimhlophe. Lokhu kuvame ukusetshenziselwa abathwebuli bezobuchwepheshe endaweni ye-studio uma kubaluleke kakhulu ukuba nombala ophelele (ngaphezulu ngalokhu ngezansi).
- I-Kelvin (uphawu-K emgqeni) ikuvumela ukusetha izinga lokushisa lombala ngokuthanda, ukunikeza umphumela oqondile. Kuwusizo uma wazi izinga lokushisa lombala womthombo wokukhanya futhi uvumela izinguquko ezenzelwe ukuhlelwa kahle.
Indlela Yokusetha Ukulinganisela Okumnyama Okumnyama
Ukubeka i-custom custom balance kubulula kakhulu futhi kuwumkhuba abathwebuli bezithombe ezinzulu okufanele babe nomkhuba wokwenza. Emva kwesikhashana inqubo iba yinto yesibili futhi ukulawulwa kombala kuwufanele umzamo ohilelekile.
Uzodinga ikhadi elimhlophe noma elimhlophe, elingathengwa ezitolo eziningi zekhamera. Lezi zenzelwe ukuba zingathathi hlangothi ngokuphelele futhi zikunikeze ukufundwa kokulinganisela kombala okunembile kakhulu. Uma kungekho ikhadi elimhlophe, khetha uhlamvu oluqhakazile lwephepha elimhlophe ongalithola futhi wenze noma yiziphi izinguquko ezilungiselelwe kahle ngokuhlelwa kwe-Kelvin.
Ukusetha ibhalansi emhlophe yenkambiso:
- Setha ikhamera ku-AWB.
- Beka ikhadi elimhlophe noma elimpunga phambi kwesihloko ngakho kunokukhanya okuqondile okuwela kuso njengoba isihloko senza.
- Shintshela ekugxilweni komuntu (ukugxila okulungile akudingekile) futhi uvale kakhulu ukuze ikhadi ligcwalise indawo yonke yesithombe (noma yini enye izolahla ukufunda).
- Thatha isithombe. Qinisekisa ukuthi ukuvezwa kuhle futhi ukuthi ikhadi ligcwalisa isithombe sonke. Uma kungalungile, qalisa kabusha.
- Zulalela ku-Balance Custom Custom emenyu yekhamera bese ukhetha isithombe esifanele sekhadi. Ikhamera izobuza ukuthi lokhu kuyisithombe okufanele sisetshenziselwe ukusetha ibhalansi emhlophe yangokwezifiso: khetha 'yebo' noma 'ok.'
- Emuva phezulu kwekhamera, shintsha imodi yebhalansi emhlophe ku-Custom White Balance.
- Thatha enye isithombe yesifundo sakho (khumbula ukuvula i-autofocus emuva!) Futhi uqaphele ushintsho ngombala. Uma kungezona okuthandayo, phinda zonke lezi zinyathelo futhi.
Amathiphu Okugcina Wokusebenzisa Ukulinganisa Okumhlophe
Njengoba kushiwo ngenhla, ungathembela ku-AWB isikhathi esiningi. Lokhu kuyiqiniso ikakhulukazi uma usebenzisa umthombo wokukhanya wangaphandle (njenge-flashgun), njengoba ukukhanya okungathathi hlangothi okukhishwe yiyo ngokuvamile kukhansela noma yikuphi ukukhishwa kombala.
Ezinye izifundo zingabangela inkinga ku-AWB , ikakhulukazi, izithombe ezinokuningi okungokwemvelo kwamathoni afudumele noma apholile. Ikhamera ingachaza ngokucacile lezi zihloko njengokukhipha umbala phezu kwesithombe futhi i-AWB izama ukulungisa ngokufanele. Isibonelo, ngendaba enokufudumala komfudumalo (amathoni abomvu noma aphuzi), ikhamera ingahle iphoqe i-tinge eluhlaza okwesibhakabhaka phezu kwesithombe ngomzamo wokulinganisela lokhu. Yiqiniso, konke lokhu okushiya ikhamera yakho nge-funny color cast!
Ukukhanyisa okuxubile (inhlanganisela yokukhanya okwenziwe ngokwezifiso kanye nemvelo, isibonelo) kungabuye kudideke ku-AWB kuma-camera. Ngokuvamile, kungcono ukubeka ibhalansi emhlophe ngokukhanyisa okukhulu, okuzokwenza konke kukhanyiswe ukukhanya okuhambile ithoni elifudumele. Amathoni afudumele athambekele ekukhangeni emehlweni kunamakhadi apholile futhi abandayo.
