Cine vs Ilensi yokufota: Ungayikhetha njani ilensi efanelekileyo yevidiyo
Unokwenza ifilimu nge-lens eqhelekileyo kwikhamera yakho yevidiyo okanye i-DSLR, kodwa ukuba ufuna ulawulo olungaphezulu, umgangatho okanye ubambe imifanekiso ethile, kusenokuba ixesha lokulahla i-lens "yekiti" eqhelekileyo kwaye wandise i-arsenal yakho.
Nazi ezinye iingcebiso ezisebenzayo zokukhetha ilensi yevidiyo.
Kule posi siza kugubungela:
Ngaba ufuna ngokwenene ilensi entsha?
Abenzi beefilim banokuthi baxakeke zizixhobo zekhamera kwaye baqokelele zonke iintlobo ze-knick-knacks abangazisebenzisi ngokwenene. Ilensi elungileyo ayikwenzi ube ngumzobi wevidiyo ongcono.
Jonga kakuhle into onayo kunye nento engekhoyo. Zeziphi izithonga ozifunayo ongekakwazi ukuzenza? Ngaba umgangatho welensi yakho yangoku uphakathi kakhulu okanye awonelanga?
Ngaba ufuna i-Prime okanye i-Zoom?
A Ilensi enkulu ilinganiselwe kubude bokujongisisa obunye/ubude bokujongisisa, umz. Tele okanye Banzi, kodwa hayi zombini.
Oku kuneenzuzo ezininzi ngeelensi ezifanayo; ixabiso liphantsi ngokwentelekiso, ububukhali kunye nomgangatho ulungile, ubunzima buhlala busezantsi kwaye ubuntununtunu bokukhanya buhlala bungcono kune Ilensi yokwandisa.
Ngelensi yokusondeza ungahlengahlengisa iqondo lokusondeza ngaphandle kokutshintsha iilensi. Kusebenza ngakumbi ukwenza ukwakheka kwakho kwaye ufuna indawo encinci kwibhegi yakho yekhamera.
Ngaba ufuna ilensi ekhethekileyo?
Ukudubula okukhethekileyo okanye isitayile esithile sokubonwayo ungakhetha i-lens eyongezelelweyo:
- lenses ngakumbi ukudubula kweMacro, xa uhlala uthatha imifanekiso eneenkcukacha ezifana nezinambuzane okanye ubucwebe. Iilensi eziqhelekileyo zihlala zingakwazi ukugxila kufutshane nelensi
- Okanye i-lens ye-Fish Eye ene-angle ebanzi kakhulu. Unokusebenzisa ezi kwiindawo ezincinci, okanye ukulinganisa iikhamera zesenzo.
- Ukuba ungathanda i-bokeh/isiphumo solufifi (ubunzulu obuncinci bebala) kwizitofu zakho apho umphambili kuphela ubukhali, ungakufezekisa oku ngokulula ngokukhawuleza (okungevani nokukhanya) I-telephoto lens.
- Nge-lens ebanzi-engile unokurekhoda umfanekiso obanzi kwaye ngexesha elifanayo umfanekiso uzinzile kunokuba udubula ngesandla. Oku kuyacetyiswa ukuba usebenza kunye neegimbals / steadicams.
Uzinzo
Ukuba unekhamera ngaphandle kozinzo, ungakhetha i-lens ngokuzinzisa. Ungayivula okanye uyivale ngokweemfuno zakho.
Ukwenza ifilimu nge-rig, i-hand-hand okanye ikhamera yegxalaba, oku ngokwenene kufuneka kube khona ukuba akukho mfanekiso wokuzinza (IBIS) kwikhamera.
Ukuqalisa ngezakho iibhodi zamabali ezishukumayo
Bhalisa kwincwadana yethu kwaye ufumane ukhuphelo lwakho lwasimahla ngeebhodi zamabali amathathu. Qalisa ngokuzisa amabali akho ephila!
Siza kuyisebenzisa kuphela idilesi yemeyile yethu kwincwadana yethu kwaye siyihloniphe eyakho wabucala
I-Autofocus
Ukuba ufota phantsi kweemeko ezilawulwayo, mhlawumbi uya kugxila ngokwenza.
Ukuba uthwebula iingxelo, okanye ukuba ufuna ukuphendula ngokukhawuleza kwimeko, okanye ukuba usebenza kunye ne gimbal (olunye ukhetho oluhle siye saluphonononga apha), kuluncedo ukusebenzisa i-lens nge-autofocus.
Ilensi yesinema
Uninzi lwe-DSLR kunye (nenqanaba lokungena) abathwebuli bevidiyo bekhamera ye-cinema basebenzisa i-lens yeefoto "eqhelekileyo". Ilensi yeCine yenzelwe ngokukodwa ukufotwa kwaye inezi mpawu zilandelayo:
Unokuseta ugxininiso ngesandla ngokuchanekileyo kwaye ngokutyibilikayo, ukutshintsha i-aperture / i-aperture ayinasinyathelo, akukho ngxaki ngokuphefumla ilensi kunye nomgangatho wokwakha uhlala ulungile kakhulu. Into engalunganga kukuba i-lens ihlala ibiza kwaye inzima.
Umahluko phakathi kwelensi yeCine kunye nelensi yokufota
Uneentlobo ezahlukeneyo zeelensi zezicelo ezahlukeneyo. Kwicandelo eliphezulu ungakhetha phakathi kwelensi yokufota kunye ne icine lens.
Ukuba usebenza kwimveliso yefilimu kunye nohlahlo lwabiwo-mali olufanelekileyo, kukho ithuba lokuba uya kusebenza kunye ne-cine lens. Yintoni eyenza ezi lens zikhetheke, kwaye kutheni zibiza kangaka?
Ubunzima obulinganayo kunye nobukhulu belensi yeCine
Ukuhambelana kubaluleke kakhulu kwimveliso yefilimu.
Awufuni ukuseta kwakhona eyakho ibhokisi ye-matte (ezinye iinketho ezinkulu apha ngendlela) kwaye ulandele ugxininiso xa utshintsha iilensi. Yingakho uchungechunge lwe-cine lens lunobukhulu obufanayo kwaye phantse ubunzima obufanayo, nokuba bububanzi okanye i-telephoto lens.
Umbala kunye nokuchasana kuyalingana
Kwiifoto, unokwahluka ngombala kwaye uthelekise iilensi ezahlukeneyo. Ngefilimu akunzima kakhulu ukuba isiqwenga ngasinye sinobushushu bombala ohlukeneyo kunye nokubukeka.
Yingakho iilensi ze-cine zenziwe ukuba zinikeze ukungafani okufanayo kunye neempawu zombala, kungakhathaliseki ukuba luhlobo luni lwe-lens.
Ukuphefumla ilensi, ukugxila ekuphefumleni kunye ne-parfocal
Ukuba usebenzisa i-zoom lens, kubalulekile nge-cine lens ukuba indawo yokugxila ihlala ifana. Ukuba kufuneka ugxininise kwakhona emva kokusondeza, kuyacaphukisa kakhulu oko.
Kukwakho iilensi apho isityalo somfanekiso sitshintsha ngexesha lokujolisa (ukuphefumla kweLens). Awuyifuni loo nto xa udubula imuvi.
Vignetting kunye T-Stop
Ilensi inegophe ukwenzela ukuba ilensi ifumane ukukhanya okuncinci ecaleni kunaphakathi. Nge-cine lens, lo mahluko ulinganiselwe kangangoko kunokwenzeka.
Ukuba umfanekiso uyashukuma, unokuwubona umahluko ekukhanyeni ngcono kakhulu kunefoto. I-F-stops isetyenziselwa ukufota, i-T-stops kwifilimu.
I-F-stop ibonisa umlinganiselo wethiyori wokukhanya odlula kwi-lens, i-T-stop ibonisa ukuba ukukhanya kungakanani ngokwenene kubetha inzwa yokukhanya kwaye ngoko ke isalathisi esingcono kunye nesigxina.
I-cine lens yokwenyani ihlala ibiza kakhulu kunelensi yefoto. Kuba ngamanye amaxesha kufuneka wenze ifilimu kwisithuba seenyanga, ukungaguquguquki kubaluleke kakhulu.
Ukongezelela, unokulindela iimpawu eziphezulu zelensi phantsi kweemeko ezinzima zokukhanyisa ezifana nokukhanyisa, ukuchasana okuphezulu kunye nokugqithisa. Umgangatho wokwakha kunye nokwakhiwa kwelensi yomelele kakhulu.
Abenzi befilimu abaninzi baqesha iilensi ze-cine kuba ixabiso lokuthenga liphezulu kakhulu.
Ngokuqinisekileyo unokuthatha imifanekiso emihle kakhulu ngeelensi zeefoto, kodwa iilensi ze-cine ziqinisekisa ukuba uyazi kakuhle into eyenziwa yi-lens phantsi kwazo zonke iimeko, kwaye oko kunokonga ixesha kwi-post-production.
F-Stop okanye T-Stop?
The F-Misa iyaziwa kuninzi lweevidiyo, ibonisa ukuba kungakanani ukukhanya okungena ngaphakathi.
Kodwa i-lens yenziwe ngamalungu eglasi ahlukeneyo abonisa ukukhanya, kwaye ngaloo ndlela ikwavala ukukhanya.
I-T-Stop isetyenziswa kakhulu ngeelensi zeCinema (Cine) kwaye ibonisa ukuba kungakanani ukukhanya okwenziwayo, kwaye oko kunokuba ncinane kakhulu.
