Ngaphandle koilensiUyilo, injongo kukubonisa umfanekiso ogqibeleleyo kwisenzi sekhamera. Ukunika ikhamera umfoti kusenokwenzeka ukuba kudala iimeko zokukhanya ezingenakucwangciswa ngumyili, kwaye isiphumo sisenokuba kukugqabhuka kwelensi. Nangona kunjalo, ngamaqhinga ambalwa, ukugqabhuka kwelensi kunokuthintelwa okanye kwamkelwe.
1. Yintoni i-lens flare?
I-lens flare sisiphumo sokubona esinokuzibonakalisa ngeendlela ezininzi. Inkangeleko yakudala yisangqa esinemibala, esiphindaphindayo esinqumla umfanekiso. Ngaphandle koko, i-lens flare inokudala iindawo ezingaqhelekanga ezingafaniyo kunye nemibala ekhutshiweyo ngaphakathi komfanekiso.
Zombini ezi ntlobo ze-lens flare zibonakala ngakumbi kwiithoni ezimnyama zomfanekiso. Nangona kunjalo, uhlobo lwe-lens flare oyibonayo luxhomekeke kuyilo lwe-lens, kunye nobukhulu, ukukhanya, kunye ne-engile yokukhanya xa kuthelekiswa ne-lens yekhamera.

2. Yintoni ebangela ukugqabhuka kweelensi?
Ukugqabhuka kwelensi kusoloko kubangelwa kukukhanya. Oku kunokuvakala kucacile (akukho kukhanya = akukho foto), kodwa ukufunda ukutolika ukukhanya linyathelo lokuqala lokuqonda ukuba kwenzeka nini ukugqabhuka kwelensi.
Ngokwesiko, ukugqabhuka kwelensi kwenzeka xa ukhomba ikhamera yakho kwicala elifipheleyo lelanga. Nokuba ilanga ngokwalo alikho kwilensi, ithuba lokugqabhuka kwelensi lihlala likho, njengoko ukukhanya okubetha ngaphambili kwelensi kwicala kuya kungena kwilensi. Okukhona ukhomba ukukhanya okungaphezulu kwekhamera yakho, kokukhona amathuba okugqabhuka kwelensi aphezulu. Nangona kunjalo, ukubonakala kokugqabhuka kunokwahluka—ingakumbi xa ilanga likwilensi.
3. Iintlobo ze-lens flare
Ezinyeiilensiukuphatha ukugqabhuka ngcono kakhulu kunezinye. Ngokubanzi, iilensi ze-zoom zichaphazeleka lula kukugqabhuka kwelensi kuneelensi eziphambili ngenxa yoyilo lwazo oluntsonkothileyo.
Kodwa ukugqabhuka kwelensi akwenzeki kuphela xa ilanga lisetyenziswa njengomthombo wokukhanya. Enyanisweni, amathuba okugqabhuka kwelensi maninzi kakhulu kubafoti base studio. Okukhona usebenzisa izibane ezininzi, kokukhona amathuba okuba enye okanye ezingaphezulu zazo zibangele ukugqabhuka kwelensi—kwaye abafoti base studio bathanda ukongeza izibane ezingaphezulu!
Iintlobo ze-lens flare
I-lens flare inokwahlulwahlulwa ibe ziintlobo ezimbini ezisisiseko. Nangona zisenokuba namanye amagama, sizibiza ngokuba yi-ghosting kunye ne-halos.
①Isiporho
I-Ghosting yindlela eqhelekileyo yokugqabhuka kwelensi, ebonakala njengamabala anemibala, aphindaphindayo okanye amile okweemilo kumfanekiso. Kodwa ngaba wakha wazibuza ukuba ezi milo zivela phi? I-Ghosting yimilo ye-lens aperture.
Ukuba i-lens aperture yakho ivulekile kakhulu, la mabala abonakala emakhulu kwaye engqukuva, kodwa ukuba uyimisa ilens phantsi, ayaba mancinci kwaye abe maninzi. Ubungakanani kunye nokuma okuchanekileyo kuxhomekeka kwiiblade zendlela ye-lens aperture. Ngokuphathelele imibala emininzi, oku kuxhomekeke kuhlobo lweglasi esetyenzisiweyo kunye neengubo ezisetyenziswa kwi-element nganye yelens.
②IHalo
I-Halo sisiphumo esingabonakaliyo esinokuthi ngamanye amaxesha singaqatshelwa kuba sisiphumoilensiukuvutha. Kulula ukukubona xa ubeka umthombo wokukhanya okhanyayo ecaleni kwemvelaphi emnyama, apho ukukhanya kungena ebumnyameni. Oku kubangelwa kukusasazeka kokukhanya njengoko kudlula kwilensi. Ukuba kwenziwe ngokuchanekileyo, umphumo unokuba mnandi ngokwenene.
Ukuthetha ngee-lens flares ezithandekayo, zama ukumisa i-lens aperture yakho iye kwixabiso layo elincinci kangangoko (inombolo enkulu ye-F) kwaye wongeze umthombo wokukhanya omncinci kwindawo leyo (ilensi ene-engile ebanzi kunye nelanga ziindibaniselwano ezigqibeleleyo). Isiphumo kukuba i-lens flare yeenkwenkwezi—akukho zihluzo zongezelelweyo ezifunekayo!
I-lens flare inokwahlulwahlulwa ibe ziintlobo ezimbini ezisisiseko
4.Indlela uhlobo lwelensi oluchaphazela ngayo ukugqabhuka kwelensi
Ewe, yinto eqhelekileyo, kodwa inyani engenakuphepheka malunga neelensi kukuba ufumana oko ukuhlawulelayo, kuquka nendlela ilensi ephatha ngayo ukugqabhuka kwelensi. Akukho lensi ikhuselekileyo kukugqabhuka kwelensi, kodwa iilensi ezingcono zisebenzisa iglasi engcono kunye nokugquma okungcono, okunciphisa kakhulu ukugqabhuka kwelensi yangaphakathi. Oko kuthethiweyo, neelensi zanamhlanje ezingabizi kakhulu ziya kuba neempawu zokuphatha ukugqabhuka okuphezulu xa kuthelekiswa neelensi zexesha langaphambi kwedijithali.
①Ingqwalasela ezinzileyoiilensi kunyei-varifocaliilensi
Njengoko bekutshiwo ngaphambili, iilensi ezigxile kwi-fixed focus zivelisa ukugqabhuka okuncinci. Ubude bazo obunye buthetha uyilo lwelensi yangaphakathi olulula olunezixhobo ezimbalwa, nto leyo ebangela umngcipheko omncinci wokusasazeka kokukhanya. Iilensi ze-Varifocal zineendawo ezihambayo, ubude obuhlengahlengiswayo, kwaye (kwezinye iilensi ze-varifocal) i-aperture etshintshayo xa i-zoom ikhula, nto leyo eyenza kube nzima ukunciphisa ukugqabhuka.
②Fubude be-ocal
Ubude befokhayi nayo ibalulekile. Kulula ukubona ukugqabhuka ngeilensi enekona ebanzi, kodwa i-flare isenokuba kwinqanaba elincinci. Ibala elibanzi lombono kunye nenxalenye engaphambili engqukuva kwenza kube lula ukuba ubambe i-flare ngengozi. Ngokwahlukileyo koko, ilensi ye-telephoto ayibonisi mngcipheko mkhulu wokutsha, kodwa xa isenzeka, idla ngokuzalisa yonke ifreyimu.
Ngokuphathelele iilensi, akukho nto ibizwa ngokuba yilensi egqibeleleyo, kodwa kukho izinto onokuzenza ukuze unciphise impembelelo yayo.

③Li-en hood
Ilensi nganye kufuneka ize ne-lens hood, kodwa ngelishwa, azinazo. Ngethamsanqa, ungathenga ii-aftermarket hood, kodwa lumka ungazivelisi xa ufota ngee-engile ezibanzi. Ukuba uluhlobo lomfoti ojika i-lens hood yakho xa uyigcina aze ayibeke ngasemva xa ufota... yeka! I-lens hood sesona sixhobo silungileyo onokusisebenzisa ukunqanda ukugqabhuka kwe-lens engaphandle kwe-axis, okuthintela ukukhanya okungena kwilensi emacaleni.
Ukuba ukukhanya kwakho kukwi-axis ethe nkqo, unokufuna ukukuvala ngezinye iindlela. Elangeni, ungaphakamisa isandla sakho ukuze wenze isithunzi, okanye ufumane into efana nesebe lomthi ukuze wenze isithunzi. Kwisitudiyo, iiflegi kunye neegridi zingasetyenziswa ukuvimba ukukhanya.
④Ukucoca ilensi
Cinga ngale nto: okokugqibela uhlola izinto zangaphambili nangasemva zelensi yakho? Uthuli, igrisi, kunye nemikrwelo zihlala zithetha ukuqaqamba ngakumbi kwelensi. Ngaba ngokwenene uyasidinga isihluzo ngaphambili kwelensi yakho? Ukuba kunjalo, ngaba sinesigqubuthelo esichasene nokukhanya? Izihluzi ezingabizi kakhulu zinokungenisa ukuqaqamba ngakumbi kwelensi.
Okokugqibela, cinga ngokuchatshazelwa. Xa umthombo wokukhanya ubonakala kakhulu, ukuchatshazelwa kuyabonakala ngakumbi. Oku kusenokungabi yinto onokuyilawula kweli candelo, kodwa yinto ekufuneka ikhunjulwe ngabafoti base studio.
Sebenzisa i-lens hood kuyo yonke ilensi
5.Nini ukuyause lii-ensfi-lare
Ngoku ekubeni unezixhobo zokulungisailensiflare, masenze okwahlukileyo koko. I-lens flare ayimbi konke konke; eneneni, inokuba ntle naphi na nanini na xa ufuna.
Ukukhanya kwelanga okuhluzwa emithini kufuna ukugqama kwelensi. Imifanekiso yasehlotyeni enegqama lensi ibamba ubushushu bemini. Bukela nayiphi na ifilimu yesayensi yanamhlanje kwaye uya kubona ukugqama kwelensi kuyo yonke indawo. Lukhetho olucwangcisiweyo lobuhle oludibanisa ubunzulu kunye nemfihlakalo kuloo ndawo.
Kubafoti beefoto, i-lens flare sisixhobo esihle sokufihla imvelaphi yesitudiyo kunye nee-light stands. Idala umdla kunye nomdla. Ukuba ufuna ngokwenene ukwamkela nokuphucula inkangeleko ekwikhamera, isihluzi se-black haze sisixhobo esihle (kodwa esihlala sihleli) endaweni yokucubungula emva koko.
Kwimeko embi kakhulu, ukugqama kwelensi kunokonakalisa ifoto entle ngokugqibeleleyo. Ewe, unokukwazi ukubuyisela ukugqama okulahlekileyo okanye ukususa iimilo ezingaqhelekanga emva kokucutshungulwa, kodwa ukuyiphepha kwasekuqaleni sisisombululo esingcono kakhulu. Beka isigqubuthelo selensi kwindawo efanelekileyo, cofa iqhosha lokujonga kwangaphambili i-aperture (ukuba ikhamera yakho inayo) ukujonga ukugqama, kwaye ukuba konke okunye kuyasilela, yenze isebenzele wena—ngenjongo nangenjongo. Kuba ukwazi “imithetho” yokufota kukunika isizathu esifanelekileyo sokuyiphula ngabom!
Iingcinga Zokugqibela:
Ngokusebenzisana neengcali eChuangAn, zombini uyilo kunye nokuveliswa kulawulwa ziinjineli ezinobuchule obuphezulu. Njengenxalenye yenkqubo yokuthenga, ummeli wenkampani unokuchaza ngokweenkcukacha ulwazi oluthile malunga nohlobo lwelensi ofuna ukuyithenga. Uthotho lweemveliso zelensi zikaChuangAn zisetyenziswa kwiintlobo ngeentlobo zezicelo, ukusuka ekujongeni, ukuskena, iidrone, iimoto ukuya kumakhaya akrelekrele, njl. IChuangAn ineentlobo ngeentlobo zeelensi ezigqityiweyo, ezinokutshintshwa okanye zenziwe ngokwezifiso ngokweemfuno zakho. Qhagamshelana nathi ngokukhawuleza.
